It converts low-level digital output commands from the HPM subsystem into isolated contact outputs for external devices.\u003c\/p\u003e\n\u003cp\u003eFurthermore, the module applies channel-to-channel isolation to reduce electrical interference between independent output points. The relay interface supports field devices such as solenoid valves, motor starters, annunciators, and alarm circuits while maintaining separation between controller electronics and external wiring.\u003c\/p\u003e\n\u003cp\u003eFor Honeywell DCS architectures, the module operates with discrete I\/O signal conditioning methods rather than analog communication protocols such as 4-20 mA HART or FOUNDATION Fieldbus.
