The Omron CRT1-ID08TA is an 8-point digital input module from the CRT1 remote I/O series. It mounts on a DIN rail and connects via a rectangular connector with screw terminals, designed to bring discrete signals back to CJ, CS, or NJ-series PLCs. Operating temperature range is -10°C to 55°C with CE and cULus approvals, so it slots into panels needing those marks.
This module interfaces with CJ/CS/NJ controllers over the CRT1 remote I/O bus. Wiring uses rectangular connectors with screw terminals for sensor inputs. No built-in diagnostics or fieldbus interface — this is a basic 8-input slice for digital sensors or limit switches.
