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. It mounts on a DIN rail and terminates via screw terminals, making it straightforward to integrate into panel builds that already use that platform.
What the ratings mean for fit
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. The 0°C to 55°C operating range suits climate-controlled enclosures but not unheated cabinets in freezing environments. 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.
