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)


Application 1

Reducing Cost and Saving Space

External devices such as converters, isolators, and power supplies are unnecessary. Up to 640 words of multipoint data logging, and data acquisition with a cycle time as short as 0.01 s in an isolated-type Unit.


A Process Analog I/O Unit, which can receive direct sensor inputs, is mounted to a SYSMAC CS-series PLC. In general, this configuration can reduce costs by 1/2 and reduce the required space by 1/3 compared to conventional systems.

  • It is not necessary to connect external isolators because the Process Analog I/ O Unit’s inputs are isolated.

  • An external power supply and distributor are also unnecessary when 2-wire Transmitter Input Units are being used.
  • PLC acquisition of temperature and analog data at speeds up to 10 ms (*1) and 16-bit resolution. Meets a wide range of application needs, from routine data measurements to laboratory requirements.
  • Energy-saving (*2) high-resolution type suitable for multipoint logging applications.

Application 2

Reducing Engineering Costs

Functionality is already built into the Unit, so programming is easy. Furthermore, settings are easy to make with the Process Analog I/O Unit Support Software.


Settings for Process Analog I/O Units and Analog I/O Units can be performed using Windows-based software.


Application 3

Constructing a High-reliability Monitoring System

Inputs are isolated


Use an Isolated-type Input Unit in the data logging system if the monitoring application requires very accurate data collection. These models provide protection against data
inaccuracies due to external noise, grounding problems, or disconnection.

Application 4

Using Inputs from Sensors in the Existing System

A Wide Range of Models for Various Signals


Process Analog I/O Units support various types of analog signal, such as thermocouple input, resistance thermometer input (Pt100, JPt100, Ni508.4 ?), 4 to 20-mA current input, 1 to 5-V voltage input, ±1-mA and 0 to 1-mA input for power transducers, and 0 to 100-mV DC input.

Supported analog signal: Thermocouple input, platinum resistance thermometer input, two-wire transmitter input, DC input, power transducer input, DC input (100 mV), pulse input and analog input.


Application 5

Allowing for System Expansion

Add a Loop Control Board for Even Greater Flexibility


When expanding the controlled system, use a Loop Control Board that is supported by the CS-series PLCs. With a Loop Control Board, function blocks can be combined freely to provide the flexibility of special control systems, such as cascade control, feed-forward control, and dead time compensation control.


Greater Flexibility with a Loop Control Board


Application 6

Providing Remote Maintenance Capability

Easy Remote Monitoring when an OMRON PLC Is Used


If the control system is built upon a SYSMAC CS-series PLC, remote maintenance can be performed easily as shown below.

  • Data can be monitored from a remote personal computer by connecting to the PLC’s host link (RS-232C) port through a modem (via a telephone circuit).
