New Products

CJ1W-PH41U Process Analog I/O Unit
(High-resolution Unit with Fully Universal Inputs)

CJ1W-AD04U Process Analog I/O Unit
(General-purpose Unit with Fully Universal Inputs)

Process Analog I/O Units

A single Unit handles all types of inputs, including temperature sensor inputs (e.g., thermocouple or platinum resistance thermometer), analog signal inputs (e.g., 4 to 20 mA or 1 to 5 V), and potentiometer inputs.

Fully Universal Inputs, Including Thermocouple Inputs, Platinum Resistance Thermometer Inputs, and DC/Voltage Inputs
The input type can be selected for each input channel, saving space and reducing costs for compact devices that use a mix of input types. And trouble-free selection of input types improves inventory control and maintenance.
General-purpose Models for Great Cost Performance and High-resolution Models for Applications Such as Semiconductor Production Equipment
These compact CJ-series Units provide four insolated input channels per Unit. Depending on the application, choose either the high-resolution CJ1W-PH41U, which provides a selection of combinations of resolutions and conversion speeds in addition to a PLC-first 1/1,000°C range (0.000 to 50.000°C, 4-wire Pt100), or the general-purpose CJ1W-AD04U, which provides superior cost performance. (See note.)

Note: According to OMRON investigation.

Features

Integrated Loop Control and Sequence Control

An engine for controlling analog quantities (e.g., temperature, pressure, flowrate) is built into the same CPU Unit as the engine for executing sequence control, delivering high-speed sequence control and high-speed, advanced analog quantity control in a single Unit.

Sequence Control Engine executes 20-kstep ladder program in 1 ms. Loop Control Engine executes PID control in 10 ms.

Small - Super compact: Only 90 mm High and 65 mm Deep, and Backplane-free structure enables flexible width design.

Compact PLC Aids Machine Downsizing by Fitting Just About Anywhere. Wide Array of I/O Units, Special I/O Units, and CPU Bus Units Are Available to Suit Your Application.

Greatly reduces space between ducts.

Fast - High-speed sequence control functions can be used directly for high-speed, advanced loop control.

Sequence control: Executes 20-Kstep ladder programs in 1 ms (with basic instructions only). PCMIX = 7.4 LD or OUT executed in 40 ns
Loop control: Executes PID operations for 20 loops in up to 10 ms. This is a guide for general applications.

High-speed processing where only one CPU unit needed.

Easy - Function blocks make loop-control programming easy. You can also create CX-Process Tool tuning windows to help adjust loops. Controller faceplates can be created automatically for touch panel displays.

Sequence control programs: Standardize and simplify programs using structured programming. Special I/O Unit and CPU Bus Unit settings are easy with function blocks (using ladder programming language or structured text).
Loop control programs: By combining function blocks, a wide array of control methods can be easily configured, from basic PID control used by Temperature Controllers to program, cascade, and feed-forward control.

Expandability - Lineup includes low-cost models that use up to 50 function blocks and models that allow up to 300 blocks designed for large-scale systems and complicated operations.

Loop control: Programming with function blocks to suit the application.
System configuration: Choose and combine functions from a broad selection of I/O Units.

System Configuration

Maintenance - Simply turn the DIP Switch ON/OFF to save or read the user program including function blocks using the Memory Card.

Simple backup function enables backup, recovery, and comparison of all PLC data including the function block programs for the Loop Control Board using the Memory Card.
Save tag settings, comments, annotations, and connection data created using the CX-Process Tool to the Memory Card.

Easy Maintenance Configuration

Result - Consolidating OMRON's expertise in temperature and process control
cultivated over many years to provide you with effortless solutions using proven algorithms.

Loop control: Proven functionality of Temperature Controllers and CS-series Loop Control Boards (see note 1) in a compact size.

Disturbance Overshoot Adjustment and Fine Tuning Features
