It is typically mounted on a terminal board (such as the TPDH) and receives power via the backplane. Its primary responsibility is to provide the controller with the status of field-side breakers, fuses, and protection relays. The 12 onboard Form-C relays allow the system to execute protection commands, such as tripping a circuit or activating alarm indicators, with extremely low latency.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eFrequently Asked Questions\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eIs the IS220PPDAH1A hot-swappable?\u003c\/strong\u003eYes, the Mark VIe architecture allows for the hot-swapping of I\/O packs like the\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eIS220PPDAH1A\u003c\/strong\u003e.
