The Omron SRT2-ROC16 is a 16-point relay output module in the SRT2 remote I/O family, designed to interface with C Series controllers.
Sixteen relay outputs cover medium-density discrete loads — solenoids, contactor coils, indicator lamps — where galvanic isolation and high inrush tolerance are needed. Screw terminals simplify field wiring; no special tooling required. Approvals from CE, CSA, and UL cover the major North American and European installation standards, so the module satisfies most plant-level compliance requirements out of the box.
System context and common misspecification
The SRT2-ROC16 is a remote I/O slice for Omron C Series racks or fieldbus adapters. It is not a standalone PLC I/O module — it requires a C Series bus coupler. A common mis-step is trying to use it as a direct replacement for a CP2E-series integrated PLC I/O; the two are architecturally different and not pin-compatible. For a CP2E-based panel, the CP2E's own I/O terminals or expansion modules are the intended fit.
Sourcing takeaway
This is a current-catalog item with predictable availability. Submit an RFQ to confirm lead time for your quantity; the module ships as a bulk unit with no special packing.
