What this remote terminal block does in the rack
The Omron SRT1-ID04-1 is a remote terminal block that expands the I/O capacity of a compatible Omron PLC system — it brings field wiring to a single termination point rather than running individual conductors back to the CPU base. Listed under PLC Expansion Modules, this unit is designed for panel-mount integration where distributed I/O reduces wiring labour and simplifies troubleshooting.
The SRT1-ID04-1 carries a mature lifecycle status — it remains in the supply channel but is not flagged as active-new-production from the factory.
As a remote terminal block in the PLC I/O & Expansion Modules category, it mounts inside the control panel and connects to the PLC via the system bus or fieldbus — reducing the point-to-point wiring from sensors and actuators back to the main rack.
