System Configuration
The following diagram shows a basic system with a CJ1W-TC001 Temperature Control Unit (4 control loops, thermocouple inputs, and NPN
outputs) and a CJ1W-TC103 Temperature Control Unit (2 control loops with heater burnout detection, platinum resistance thermometer inputs,
and NPN outputs).
Note that this system configuration is given strictly as an example. When constructing an actual system, check the specifications, performance,
and safety of each component by referring to the respective manuals.

Note: 1.
An OMRON E54-CT1 or E54-CT3 Current Transformer must be used as the Current Transformer (CT). Do not use any other Current
Transformer.
2.
Turn ON the Stop Bit for the loop to stop temperature control. If PID control is being used and the heater is turned OFF using an operation
switch input to the heater, PID control performance will be adversely affected.
3.
To connect this Unit to the NJ series, set pin 3 "Data storage/display format" of the DIP switch to ON.

Accuracy ratings are given for the Temperature Control Unit used in a set with a cold-junction compensator (on the terminal block). Always
use the Unit and terminal block in a set. There are labels with serial numbers attached to the terminal blocks and Units to help keep track of
the sets.
