CS-series Process Analog I/O Units
CS1W-PTS/PDC/PTW/PTR/PPS/PMV
Provides the functionality of
isolators, power supplies, signal
converters, and other devices.
The Analog Inpu t Unit converts analog input signals
such as 1 to 5 V or 4 to 20 mA into digital values, and
takes the values scaled in industrial units, an d
transfers it to the CPU Unit as the process value.
Because of this, no ladder program is required at the
CPU Unit for scaling.
The Analog Output Unit co nverts analog output set
values from the CPU Unit to analog output signals
such as 4 to 20 mA or 1 to 5 V, and outputs them.
The built-in functions, such as measurement value
alarms, rate-of-change calculations, and square roots, have enabled major savings in cost and space compar e d
with previous systems.
High-resolution Models and 8-point Input Models are also available. By combining the Un its, logging/monitoring
systems can be constructed, or the Units can be used toge ther with LCBs/LCUs to construct complete process
control systems.
Parameters can be easily displayed and set in an easy-to-understand form without special tools.
Features
Process Analog Input:
Up to eight analog inputs can be connected for each Unit.
There is isolation between input channels, so unwanted circuit paths between thermocouple inputs can be prevented. (Except for CS1W-PTR01/
02)
Output scaling (±32,000)
Process value alarms (HH, H, L, LL)
Input disconnection alarm
Rate-of-change calculation and alarm
Top/bottom/valley hold (CS1W-PTS11/PTS12/PDC11 only)
Process Analog Output:
Up to four analog set values can be output for each Unit.
All outputs are isolated.
Output rate-of-change limit
Output high/low limits
Output scaling (±32,000)
Control output answer input (CS1W-PMV01 only)
Isolated-type Pulse Input:
Provides up to four pulses from a device such as a displacement flowmeter. The accumulated value can also be calculated at the same time
and transferred to the CPU Unit at each cycle. (CS1W-PPS01)

System Configuration
These Process Analog I/O Units belong to the CS-series Special I/O Unit group.
They can be mounted to CS-series CPU Racks or Expansion I/O Racks.
They cannot be mounted to C200H CPU Racks, Expansion I/O Racks, or SYSMAC BUS Remote I/O Slave Racks.
The number of Units that can be mounted to one Rack (either a CPU Rack or Expansion I/O Rack) depends upon the maximum current supplied
by the Power Supply Unit and the current consumption by the other Units.
There are no restrictions on Rack position.
Note: I/O addresses for Special I/O Units are allocated according to the unit number set on the switches on the front panel, and not according to
the slot position in which they are mounted.

Sensor type, input range, and scaling to industri al units are
separate for each of the 4 inputs.
Note: Sensor type, input range, and scaling to industrial
units are set in the DM Area.
Input ranges
The input range can be set within any of the measurable
input ranges shown in Table 1 (below).
Note: Internally, inputs are processed in five ranges (refer
to Table 2 below), so accuracy and resolution
accord with these internal ranges.
Example:
Thermocouple: K; input range: 0 to 500°C; industrial unit
scaling: 0 to 500°C. DM Area settings are as follows:
Thermocouple: 3 (0003 hex)
Input signal maximum: 5000 (1388 hex)
Input signal minimum: 0 (000 0 hex)
Industrial unit maximum value stored: 500 (01F4 hex)
Industrial unit minimum value stored: 0 (0000 hex)
Scaling in industrial units Data to be stored in the allocated words in the CIO area
must be scaled (with the minimum and maximum values
set). Data can be stored at 0% to 100%.
Data storage in the CIO Area The value derived from carrying out the following processing in order of the actual process data in the input range is
stored in four digits hexadecimal (binary values) in the allocated words in the CIO Area.
1) Mean value processing 2) Scaling 3) Zero/span adju st ment 4) Output limits

Sensor Types and Input Ranges
The temperature sensor (thermocouple) type and input range are set in the allocated words in the DM Area for every four inputs. The input range
can be set anywhere within the measurable input ranges shown in Table 1.
Table 1: Measurable Input Ranges
Note: Set the input range in the DM Area within this range.
Inputs are processed internally in five progressive ranges (numbers 0 to 4), as shown in the following table.
Table 2: Internal Ranges
Therefore, the accuracy and resolution are determined by the ratio of the selected internal range (0 to 4) span to the set input range span
(electromotive force converted value). For the internal range, a larger number is selected when both the minimum and maximum values of the
range fall within that next range.
For example, suppose that the thermocouple type is K and the set input range is 0 to 800°C. The electromotive force for K 0 to 800°C is 0 to 33.277
mV. Since both the minimum and maximum values fall within the limits for internal range No. 1 (40 to 40 mV), that range will be selected.
The following table shows the set input ranges corresponding to the internal range numbers 0 to 4.
Table 3: Set Input Ranges Corresponding to Internal Ranges
Note: With Thermocouple Input Units, process values can be scaled in industrial units for the set input range. It is possible to set the process value
scaling higher than the resolution, but it will cause the values to be unstable.

Terminal Connection Diagram
Note: 1. Cold junction sensors are installed between A2 and A3, and between A8 and A9 when the product is shipped. Do not remove them when
using the Unit. If they are removed, temperatures cannot be measured correctly because there will be no compensation.
2. Use the same cold junction sensors that come with the Unit, and leave them just as they are. They are provided specifically for this Unit
and its circuitry, and temperatures cannot be measured correctly if they are switched around or if another Unit's sensors are used in their
place.
3. For unused input terminals, short-circuit the positive and negative sides (e.g., terminals A4 and B4 for input No. 1) of the thermocouple
inputs with the lead wire.
4. When connecting input No. 4, remove the cold junction sensor between CJ2+ and CJ2, and then reconnect it after the input is
connected. Attempting to connect the input without removing the cold junction sensor may result in damage to the sensor.

Note: The method for calculating the error in temperature measurements, including the temperature coefficient, is given below. The "full scale of
electromotive force" is the difference between the high limit and low limit converted to electromotive force for each thermocouple.
Example
Ambient temperature: 30 °C
Temperature Sensor: K thermocouple (270 to 1,372 °C)
Measured temperature:500 °C
From electromotive force table
270 °C: 6.458 mV
1,372 °C: 54.86 mV
Full scale: 61.344
Electromotive conversion of temperature coefficient:
61.344 mV × ±0.01%/°C = ±6.13 μV/°C
Error in electromotive force at 30°C:
±6.13 μV/°C × (30°C 25°C) = 30.65 μV/°C
Temperature difference between measurement point and terminals on Unit (ambient temperature) (based on ambient temperature of 30 °C and
Measured temperature of 500 °C):
470 °C
Electromotive force per °C at a measured temperature of 470 °C (from the electromotive force tables for a K thermocouple):
43 μV/°C
Error in measured temperature = Accuracy ± Error from temperature coefficient + Error in cold junction compensation = ±0.8°C + ±0.7°C +
±1.0°C = ±2.5°C
Sensor Type and I nput Range
The Temperature Sensor type and input range are set in the allocated words in the DM Area for every four inputs. The input range can be set
anywhere within the measurable input ranges shown in the following table. Accuracy and resolution, however, are not determined from the set
input range, but rather from the measurable input range shown in the following table. Therefore, accuracy and resolution do not change even when
a narrow input range is set.
External connections Terminal block (detachable)
Unit number settings Set by rotary switches on front panel, from 0 to 95.
Indicators Three LED indicators on front panel (for norma l operation, errors detected at the Thermocouple Input Unit , and errors
related to the CPU Unit).
Front panel connector Sensor input connector terminal block (detachable)
Effect on CPU Unit cycle time 0.3 ms
Current consumption (supplied from
Power Supply Unit) 5 V DC at 120 mA max., 26 V DC at 80 mA max.

Terminal Connection Diagram
Note: Action for Unused Input Terminals
Short-circuit the positive (+) and negative () sides of the thermocouple input section using a lead wire. For example, short terminals A3
and A2 for No. 1 thermocouple input.
Cold junction sensors are mounted before shipment. If one of the cold junction sensors is disconnected, cold junction compensation will
stop and correct measurement of temperatures cannot be made. Always make sure the cold junction sensors are connected when using
the Units.
Cold junction sensors are calibrated separately for each Unit and connected circuit, so correct temperatures will not be measured if a cold
junction sensor from another Unit is used or if the two cold junction sensors in a Unit are swapped. Use the cold junction sensors as they
are provided, without making any changes.
Do not connect anything to NC terminals. Do not use NC terminals as relay terminals.
Always ground the GR terminal on the Power Supply Unit of the PLC.
If the input device uses a voltage generator, temperature compensator, or similar device, then ground the input device if it has a ground
terminal.

Reference accuracy (25°C) ±0.3°C of PV or ±1°C, whichever is greater, ±1 digit.
In this example, ±1.5°C.
Temperature characteristics 400 to 1,300°C: 285 ppm of PV.
In this example, 285 ppm × 500°C = 0.143°C.
Change in ambient temperature 5°C (25 to 30°C).
