The 2-channel relay output module activates intrinsically safe circuits, powering actuators in hazardous locations. The electro-mechanical 750-538 carries two changeover contacts for activating Zone 0/20 and 1/21 devices, e.g., relays, solenoid valves, contactors or optical/acoustic signal generators. This supports diverse hazardous location applications in oil/gas processing, wastewater treatment, brewing/distillation and more.
