The SRT2-ID16T: It pulls its operating power from a 24VDC supply rail, and each input channel reads a 24V nominal signal from the field device (limit switch, proximity sensor, pushbutton). The module is approved CE, CSA, and UL, so it passes inspection in most North American and European panels without a separate agency review.
Compatibility and configuration
This module is listed for use with Omron C Series PLCs — the backplane connector and bus protocol match that family, so it slots into an existing C Series rack without a gateway or adapter. No separate software configuration is required for the module itself; the I/O map is established when the rack is powered and the CPU scans the bus.
