DMS-20PC Series www.murata-ps.com 31/2 Digit, LED Display, Low-Cost, Subminiature Digital Panel Voltmeters New e wer blu Low-po LEDs en and gre FEATURES DMS-20PC Series, 31/2 Digit, LED Display, Digital Panel Voltmeters combine a precision A/D converter; a factory-trimmed, highly stable, voltage reference; and a large (0.37"/9.4mm), easy-to-read LED display in a single package that is only slightly larger than the display itself. Displays are offered in either red, orange, amber, yellow, green or blue colors. High-intensity and low-power (35mW total) red LEDs are also optional. These low-cost meters are fully self-contained and fully functional. Their subminiature (1.38" x 0.88" x 0.48"), epoxy-encapsulated cases incorporate built-in color filters and bezels; are moisture and vibration proof; and function well in the harshest environments. Their 12-pin, dual-in-line configuration offers component-like, plug-in convenience and maximum versatility. Operating temperature range is 0 to +60C. The meters come with one of four, differential, input voltage ranges: 200mV, 2V 20V or 200V. Input impedance is a minimum 800k. CMRR is typically 86dB (dc to 60Hz), and CMV is 2V. Input overvoltage protection (on the non-inverting input) is 250V. Devices are fully calibrated at the factory to an accuracy of 1 count (0.05% of full scale range) and never require calibration or adjustment. A DISPLAY ENABLE function permits the display to be disabled for "power-down" operation. All models have a DISPLAY TEST function. Standard red LED models offer an optional DISPLAY HOLD function. Small size, low cost and adjustment-free reliability make the DMS-20PC Series the best choice for all your 31/2 digit, LED, DPM applications.

The DISPLAY HOLD function is optional on standard red and green LED models only. TECHNICAL NOTES RoHS Compliant Parts: Add "-C" suffix to part number. 1. REFERENCE OUTPUT (Pin 8) and INPUT (Pin 7): Pin 8 is a precision reference actively trimmed at the factory. In normal operation, pin 8 must be tied to pin 7 to achieve all listed accuracy and drift specifications. 2. ANALOG COMMON (Pin 10): This pin is connected to an internal, low-noise, "relative" ground. It is used in certain differential and "floating" measurements as described in the Applications section of this data sheet and Ap Note DMS-AN3 at http://www.murata-ps.com/data/meters/dms-an3.pdf. Pin 10 should not be connected to pin 3 (5V RETURN) or to your system's analog ground. 3. Decimal Point Placement: The location of the decimal point is userselectable, and the decimal point control pins (DP1-DP3) are active low functions. Select the appropriate decimal point by tying the appropriate pin (pin 4, 5 or 6) to pin 3 (5V RETURN). Unused decimal point location pins should be left open. Hard wiring is preferable, however, you can use logic gates to exercise dynamic control over the location of the decimal point if the following drive conditions are met: Model Applied "0" Voltage Load Current* DMS-20PC-X-XL +0.05V max. 0.7mA max. All Others +0.4V max. 6mA max. * The driving gates must be able to sink this much current www.murata-ps.com/support MPM_DMS_20PC.F01 Page 2 of 6 DMS-20PC Series 31/2 Digit, LED Display, Low-Cost, Subminiature Digital Panel Voltmeters 4. DISPLAY TEST/HOLD (Pin 9) Function: Pin 9 is a dual-function pin. On all standard models (without "-H" suffix), tying pin 9 to pin 1 (+5V SUPPLY) activates the meter's DISPLAY TEST feature. All display segments, except the decimal points, will be illuminated. The display will show "1888" ("-1888" if a negative input signal is present). Do not leave the meter in the test mode for more than 10 seconds as this will cause the meter's operating temperature to rise and possibly affect its performance. Pin 9 must be left open when the test function is not being used. On models with the "-H" suffix (DMS-20PC-1-RS-H for example), pin 9 serves as a DISPLAY HOLD control pin. Tying pin 9 to +5V SUPPLY (pin 1) on these models will hold or "freeze" the current display reading indefinitely. Pin 9 must also be left open when the hold function is not being used. After disabling DISPLAY HOLD, allow the meter a full 10 seconds to resume normal calibrated operation before holding a new reading. The DISPLAY TEST or DISPLAY HOLD pin should normally be connected, via a selector switch, to pin 1 (+5V SUPPLY). If automatic, logic-controlled operation is desired, only PNP or MOSFET transistors should be used. The base or gate of these transistors should be driven sufficiently hard to bring pin 9 within 0.05V of +5V SUPPLY. 5. DISPLAY ENABLE (Pin 2) Function: On all models, tying pin 2 to pin 1 (+5V SUPPLY) applies full power to the LED display. This is the normal mode of operating the meter. Leaving DISPLAY ENABLE open (no connection), only turns off the LED display. The meter's analogto-digital converter continues to sample the input signal. Total current consumption with the display off is approximately 400A (0.4mA). This is a very useful feature if the meter is used in battery-powered equipment. With the exception of the low-power red LED models (DMS-20PC-XRL), a regulated voltage lower than +5V SUPPLY can be used to dim the display intensity. Display intensity control is best performed with the high brightness, red LED, DMS-20PC-X-RH model. All low-power red LED models must have DISPLAY ENABLE tied directly to pin 1 (+5V SUPPLY). Voltages applied to DISPLAY ENABLE must never be greater than +5V SUPPLY. 6. Gain Adjust: There is a gain-adjust potentiometer on the back of each meter. It has approximately 50 counts (2.5%) range of adjustment. Since these devices essentially have no zero/offset errors, a gain adjustment is effectively an overall accuracy adjustment. Though they may be performed at any point (except zero), accuracy adjustments are most effective when performed with higher level input signals. The circuit shown in Figure 10 provides 10% range of adjustment. 7. Soldering Methods: All models in the DMS-20PC Series easily withstand most common wave soldering operations. We recommend, however, that you evaluate the effects your particular soldering techniques may have on the meter's plastic case and high-precision electrical performance. We recommend the use of no-clean solders. 8.

The application circuits chosen for this section are ones that have historically received many inquiries. The schematic in Figure 1 shows that the meter's high-impedance input consists of an op amp powered from a 5Vdc power supply (the -5V is internally generated). One can easily see why input signals applied to (-) INPUT LO and (+) INPUT HI have to be kept within the power supply rails of 5V. Also note that only pin 11 has a current-limiting 909k series resistor. High input voltages that have a common ground with pin 3 (5V RETURN) should only be applied to pin 11 ((+) INPUT HI) and never to pin 12. In these high-voltage cases, pin 12 should always be tied to pin 3 (5V RETURN). The schematic also shows that pin 3 is the meter's zero-volt reference point -- regardless of the type of power or signal source used. This is an important point to keep in mind when a digital or analog multimeter is used to make system measurements. The multimeter's negative lead (usually the black one) must be connected to pin 3 (5V RETURN). 1. Single-Ended Input Configurations: True single-ended measurements can be made with any DMS-20PC meter. The circuit of Figure 2 avoids problems normally associated with ground-loop currents. Separate ground runs should be used for 5V RETURN (pin 3) and (-) INPUT LO (pin 12).

Differential Input Configurations: Differential measurements can be made with all DMS-20PC meters. Figure 3, though not a practical real-world application, uses a voltage divider to demonstrate the concept of a differential input signal.

Engineering Scaling: For measuring voltages greater than the full scale input range of a given meter, the input signal must be attenuated. A simple voltage divider (similar to that shown in Figure 4) will scale the input to within the range of the selected meter. R1 and R2 should be precision, 1%, metal-film resistors with absolute TCR's less than 50ppm/C.

Process Control (4-to-20mA) Measurements: In many common process-control applications, a 4-to-20mA current loop is used to transmit information. Because DMS-20PC meters have such high input impedance, a simple shunt resistor across the meter's input can be used to convert the loop current to a voltage. See Figure 7. The value of the shunt resistor is a function of the scaling requirements of the particular application and can be calculated using the following equation: RShunt = R1 = VFsr / I Fsr AC to DC Converter Figure 4. Input Attenuation Circuit Where: VFsr = Full scale reading (in Volts) I Fsr = Relative full scale current (in Amps) www.murata-ps.com/support MPM_DMS_20PC.F01 Page 4 of 6 DMS-20PC Series 31/2 Digit, LED Display, Low-Cost, Subminiature Digital Panel Voltmeters APPLICATIONS Example: For a meter with a 2V full scale input (1.999 full scale reading) and a desired display reading of "1000" (with an input of 20mA), VFsr = 1.000 Volts The LM-2931 was chosen because it has the following on-chip protection features: reverse polarity, short circuit and thermal runaway. When using other, higher-power, DMS-20PC models with three-terminal regulators, be sure to consult the regulator manufacturer's data sheet to ensure the regulator is being utilized safely and correctly. RShunt = 1.000V/(0.020 - 0.004)A RShunt= 1.000V/0.016A = 62.5 Ohms To calibrate the circuit of Figure 7, perform the following: 1. With 4mA applied, adjust the 50k potentiometer (R2) to display a reading of "000" (assuming that is the desired reading). 2. With 20mA applied, adjust the gain-adjust potentiometer on the back of the meter to display a reading of "1000". For different full scale readings, alter the value of RShunt accordingly. 11 (+) IN HI DMS-20PC-1 7. Digital Ammeter: Digital ammeters are finding ever-increasing usage because analog-style ammeters (moving-vane types) now cost roughly the same as their digital counterparts. Additionally, analog ammeters are not nearly as rugged as modern digital panel voltmeters. Figure 9 illustrates a typical ammeter application. The circuit uses a 200mV input meter -- the preferred range for most ammeters -- to measure the voltage developed across a 0.1 current shunt. The circuit shown represents a basic ammeter connection diagram.

Basic DC Ammeter Circuit 6. Power Supply Monitoring: One of the most common digital panel meter applications involves monitoring the output voltage of the system power supply -- often this supply also powers the meter itself. The low-power, red LED DMS-20PC-2-RL can be configured to allow power supply monitoring over the range of 4.5-18Vdc. The circuit in Figure 8 uses a low-drop-out, three-terminal regulator (LM-2931Z-5, available from National Semiconductor) to provide regulated 5V-power to the meter. 8. External Gain Adjustment: Connect REFERENCE OUT (pin 8) to REFERENCE IN (pin 7) for normal, factory calibrated, operation. Use the circuit shown in Figure 10 for applications needing external gain adjustment. Calibration is performed with a precise, near-full-scale, input voltage.
