Applications

Reflow oven uses the CJ1G for temperature monitoring

and control, and data logging

pulse I/O and built-in inputs/outputs

Typical Configuration

Basic Configuration

A CJ1 Series basic configuration

consists of a CPU, power supply unit,

and up to 10 basic I/O, special I/O and

bus units, and an end cover. Add up the

current consumption for all the modules

and the CPU, then select the power

supply unit suitable for the application.

CPU and Expansion Racks

If the number of modules per rack

exceeds 10 or the current consumption

is greater than the capacity of the

power supply units, use the CPU and

expansion rack configuration. This

divides the load from the modules

across two power supply units. To allow

communication and automatic channel

assignment in programming, order an

I/O control module for the CPU rack and

an I/O interface module on each

expansion rack.
