The OMRON SRT2-ROC16 is a 16-point remote relay output terminal block engineered for CompoBus/S industrial automation networks. It delivers high-speed, long-distance signal switching between master controllers and distributed field devices through multi-drop or T-branch topology. Each output point incorporates a G6D-1A relay for independent load control.
