The OMRON SRT1-ROC16 is a 16-point transistor remote terminal block engineered for distributed I/O control in Omron PLC systems. It delivers relay-based output switching via integrated G6D relays, reducing field wiring complexity and installation footprint across CompoBus/S networks. Built on high-quality PWB construction with DIN track and screw mounting options, this unit operates at 24 VDC ±10%/–15% with 350 mA maximum current draw and supports high-speed (750 kbps) communication over distances to 500 m using multi-drop or T-branch topologies.
