Overview
The CP1W-16ET1 is an Omron CP1W-series output module packing 16 solid-state outputs at 24 V, terminated on screw terminals for a DIN-rail mount. It mates with the CJ and CP1 series PLC backplane. It carries CE, Lloyd, and NK approvals and is in active production, so it remains a current catalog choice for new builds and spares.
Compared to the CP1W-32ER, which switches 32 relay outputs, the CP1W-16ET1 gives you 16 solid-state outputs — half the channel count but with faster, silent switching and no mechanical wear. Pick the CP1W-32ER when you need more relay-driven loads; stay with the CP1W-16ET1 for high-cycle transistor duty.
