■ Unit Description
The CJ1W-TS561 is a 6-channel input unit for K-type and J-type
thermocouples. It can be installed in any CJ1-series PLC system.
It is classified as a basic I/O unit, occupying 48, 64 or 96 I/O points,
depending on the number of activated inputs.
Always verify that the maximum I/O capacity of the CJ1 CPU is
sufficient for the number of required I/O points.

■ Wiring
•
Keep the thermocouple wiring as short as possible to avoid
electrical interference. Shielded wiring is recommended.
•
When extending input wiring, always use compensation wires
appropriate for the thermocouple type.
•
For activated but unused inputs, short-circuit the + and -
terminals, to prevent unstable readout on the other inputs.
•
Keep the input wiring away from power lines including AC power
supply lines and high-power lines. Do not run the I/O lines in the
same duct or conduit as power lines.
•
The input circuits are galvanically isolated from the PLC's I/O bus,
but there is no galvanic isolation between individual inputs.
•
Always ground the terminal on the Power Supply Unit of the
PLC. In case of shielded sensor wiring, connect the shields to the
same grounding point as the PLC.
