• A Unit supports four input channels, each of which can be set to a
platinum resistance thermometer, thermocouple, and DC signal
(current, voltage). All inputs are isolated.
CJ1W-PH41U
CJ1W-AD04U
Features
•
Supports a maximum of four inputs in one Unit: resistance thermometer, thermocouple, and DC current/voltage. (The input type is set separately
for each input.)
•
Isolation between input channels prevents unwanted current paths between input channels.
•
Scaled values are transferred to the CPU Unit in four digits hexadecimal with voltage/current inputs.
•
Process value alarm with two alarms for each input
•
Alarm ON-delay timer and hysteresis for process value
•
Zero/Span adjustment capability during operation
•
Input error detection
•
Maximum or minimum process value can be specified for when an input error is detected.
•
A Unit with fully universal inputs, high-speed and high-resolution (256,000 resolution, 60 ms/ch is available.)

System Overview
These Analog I/O Units belong to the CJ-series Special I/O Unit group.
•
They can be mounted to CJ-series CPU Racks or Expansion I/O 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.
10 I/O Units max.
