It converts low-level controller commands into electrically isolated relay signals, allowing secure operation of external devices such as shutdown solenoids, alarm circuits, and control interlocks.\u003c\/p\u003e\n\u003cp\u003eThis module is commonly deployed within Woodward MicroNet and MicroNet Plus platforms, where deterministic response, electrical isolation, and long service life are mandatory.\u003c\/p\u003e\n\u003ch3\u003e\n\u003cstrong\u003eFunctional Characteristics\u003c\/strong\u003e\n\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003e5441-695\u003c\/strong\u003e provides multiple independent relay channels that support both normally open and normally closed logic, enabling flexible configuration for permissive, alarm, and trip functions. Each output channel is electrically isolated from the control electronics, reducing the risk of fault propagation from field wiring back into the controller.\u003c\/p\u003e\n\u003cp\u003eRelays are designed for frequent switching under industrial loads and include internal measures to mitigate contact wear when driving inductive devices.\u003c\/p\u003e\n\u003ch3\u003e\n\u003cstrong\u003eRelay Output Specifications\u003c\/strong\u003e\n\u003c\/h3\u003e\n\u003cp\u003eThe module contains sixteen discrete relay outputs intended for direct control of field equipment.
