Product details

Integrator note – two-channel RTD controller

The Omron CJ1W-TC103 is a dedicated two-channel RTD temperature control module for the CJ-series backplane. It accepts 2 analog RTD inputs and drives 2 solid-state outputs, all through screw terminals. Approved for CE, cULus, and marine applications (Lloyd, NK).

CJ1W-TC103 vs CJ1W-TC001 – not a drop-in

Physically identical form factor and same CJ-series family, but the CJ1W-TC001 offers 4 analog inputs (thermocouple types B/J/K/L/R/S/T) and 4 solid-state outputs, versus the CJ1W-TC103's 2 RTD-only inputs and 2 outputs. Wiring and I/O mapping differ significantly; the TC001 cannot read RTD sensors without external converters, and the TC103 cannot read thermocouples. If your BOM calls for 4 loops of thermocouple input, the TC001 is the correct part – the TC103 is for smaller RTD-specific applications.

Screw terminals are used for field connections.

Frequently asked questions

Can the CJ1W-TC103 be replaced by the CJ1W-TC001 without rewiring?

No. The CJ1W-TC001 has 4 thermocouple inputs and 4 outputs, while the CJ1W-TC103 has 2 RTD inputs and 2 outputs. They are not electrically or functionally interchangeable. The panel would require rewiring and reconfiguration.

What approvals does the CJ1W-TC103 carry?

The module is approved for CE, cULus, Lloyd, and NK (Nippon Kaiji Kyokai). This covers European, North American, and marine classification requirements.

What input types does the CJ1W-TC103 support?

It supports RTD inputs only. The exact RTD types (e.g., Pt100, Pt1000, Ni100) are programmed via the PLC – the module itself handles two analog RTD channels.
