Omron SYSMAC C200H-RT201 Remote I/O Slave Unit | Programmable Controller Module

Expand your industrial automation network with the highly reliable Omron C200H-RT201 Remote I/O Slave Unit. Part of the legacy SYSMAC C200H Series, this programmable controller module acts as a decentralized slave node, allowing long-distance communication between a master PLC unit and distributed input/output devices on the factory floor without excessive hardwiring.

The unit is equipped with a versatile power transformer supporting dual operating voltages: 100–240 VAC. It can be configured for a 100–120 VAC line by bridging the designated terminals, or left open for a 200–240 VAC electrical supply. For communication, the module features a dedicated RS485 differential terminal block at the lower left to ensure high-speed, noise-resistant data serialization over extended twin-axial wiring runs. The front display panel hosts clear diagnostic LED indicators—including RUN, XMT/RCV (Transmit/Receive), POWER, ERROR1, and ERROR2—allowing maintenance technicians to troubleshoot link statuses at a glance. Additionally, a built-in, front-accessible 250V / 2A fuse port safeguards internal components from unexpected overcurrent events.
