■ Unit Description
The CJ1W-TS562 is a 6-channel input unit for Pt100 and Pt1000
RTD’s. 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
• Use the same length and type of leadwire for each RTD’s
terminals A, B, and B’, so that the leadwire impedances will be
the same. 2-wire connection can be used by shorting B-B’, but
the specified indication accuracy cannot be guaranteed.
• For activated but unused inputs, short-circuit the A–B and B–B’
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. All B’
terminals are interconnected in the unit.
• 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.

Description
Fatal error or no power supply.
• Check the host PLC’s CPU status, and the
status of other I/O units. If all other units
function normally, replace the Unit
Unit functions normally.
No fatal errors.
Incorrect DIP switch setting
Fatal error in the Unit.
• Check the CPU unit for error codes.
• Re-start the PLC system.
• If the ERC LED is still lit, replace the unit.
• Measurement of the corresponding channel is
within range, or
• Channel has been deactivated by DIP switch
settings
• Measured temperature out-of-range, or
• RTD broken wire or short circuit
Calibration data not found or incorrect. The Unit
should be returned to OMRON for calibration.
