What it is and what it does
The CJ1W-TC104 is a CJ1W-series Temperature Control Module from Omron, designed for RTD sensors. It provides 2 analog inputs for RTD probes and 2 solid-state outputs for driving heaters or alarms. Mounts on a DIN rail and terminates via screw terminals. Approved under CE, cULus, Lloyd, and NK – covers general industrial and marine environments.
How it compares to nearby siblings
The CJ1W-TC004 shares the same 2-in/2-out count but is designed for thermocouples (types B, J, K, L, R, S, T), not RTD. If your process uses thermocouples, the TC004 is the correct choice; if RTD, it is the TC104.
Integration notes
Screw-terminal connections suit field wiring, accepts standard RTD probes. DIN-rail mount, compatible with Omron CJ Series backplane. Full approvals reduce project paperwork.
