What it is
The Omron CS1W-PTS02 is a 4-channel analog input module for the CS Series PLC platform. It mounts on a backplane and terminates via screw terminals, handling standard analog signals in the 0°C to 55°C operating range. CE and cULus approved, so it's suited for control panels in industrial and utility environments, including water/wastewater lift stations where temperature and level transmitters feed into a CS1 rack.
Integration – backplane and wiring
Screw terminal connections per channel; strip length and torque follow Omron's standard for the CS1W series. The module snaps onto the CPU rack or an expansion backplane without occupying extra DIN-rail space.
Sibling modules – choosing between CS1W-PTS02, -03, -51, -56
The CS1W-PTS02 is the standard 4-channel analog input. If you need a drop-in functional equivalent with identical form and wiring, the CS1W-PTS03 carries the same specs. For thermocouple inputs (types B, J, K, L, R, S, T), the CS1W-PTS51 adds that capability. For higher channel density, the CS1W-PTS56 provides 8 analog inputs in the same footprint.
