The module provides 16 isolated relay channels for direct control of field switching devices including trip solenoids, breaker interfaces, ESD isolation valves, and alarm circuits.\u003c\/p\u003e\n\u003cp\u003eThe relay output structure supports I\/O density scaling by providing multiple independent switching channels within a single rack interface. Galvanic isolation between relay circuits and the controller backplane reduces ground loop effects and electrical interference coupling.\u003c\/p\u003e\n\u003cp\u003eThe board communicates through the Mark VIe proprietary IONet bus architecture. Relay feedback sampling at 100 Hz provides status monitoring of output conditions within the control system.\u003c\/p\u003e\n\u003cp\u003eThe AAA revision includes full conformal coating on the PCB assembly.
