DYNAPAR brand R Tach 1 & Tach 2 Rate Indicators/Controllers Excellent performance is coupled with flexibility and small package size 4 The Dynapar MAXjr Tach family set the standard for low cost industrial rate controllers. Programmable calibration factor and decimal point allow speed to be displayed in units, such as: feet/minute, gallons/ minute, etc. Combining high accuracy measurement with alarm capability, built-in diagnostics, large, bright LED display, simple programming and compact size makes the MAXjr Tachs a best value. Calibration factor allows display in engineering units 0.01% accurate time interval measurement SPECIFICATIONS Panel Mounting: 1.78" x 3.56" cutout; 5.68" depth Accuracy: 0.01% crystal controlled Inputs: Magnetic (sine wave), pulsed (square wave) open collector, TTL, CMOS or line driver; 10 kHz max. Display: 5 digit, 0.56" LED; update rate 0.7 seconds or 1 signal period Large, bright 0.56" high red LED display Alarms: 1 each high and low; open collector outputs Full 5 digit display capability High and low alarm setpoints with outputs Calibration: Programmable 0.0001 to 99999. Sealed NEMA 4 front panel Power Requirements: 95 to 130, or 190 to 260 VAC, 50/60 Hz, 6 VA; 10 to 26 VDC @ 0.4 A max. Programmable decimal point position Accessory Power: + 12 VDC 25% @ 0 to 125 mA Built-in diagnostics The MAXjr Tach 1 Rate Indicator/Controller performs the basic rate or speed measurement functions. The MAXjr Tach 2 provides a choice of operating modes: rate of input A, as in the MAXjr Tach 1; ratio of two independent inputs A and B; and time interval, which can be the period of A or the elapsed time between inputs A (start) and B (stop). Operating Temperature: 32 to +122F (0 to +50C) Model No. Description MTJR1S00 MTJR1D00 MTJR2S00 MAXjr Tach 1 Rate Controller, 115 or 230 VAC MAXjr Tach 1 Rate Controller, 10 to 26 VDC MAXjr Tach 2 Rate/Ratio/Time Interval Controller, 115 or 230 VAC MAXjr Tach 2 Rate/Ratio/Time Interval Controller, 10 to 26 VDC For RPM display without alarms, see SimTach D For voltage or current loop inputs, see PM64S MTJR2D00 Typical Applications: Dimensions: Encoder With Measuring Wheel 3.78" 96 mm .39" 10 mm .50" 13 mm 5.20" 132 mm 3.54" 90 mm 1.67" 42 mm 1.98" 50 mm FRONT SIDE Web Speed MAXjr Tach DANAHER INDUSTRIAL CONTROLS 4.09 R a A n T d E C I O NN D T I R C O A L T L O E RR S S
