Engineered with an isolated signal design, it effectively isolates field-side electrical noise from the backplane, ensuring stable CPU operation. The hardware supports an independent interrupt function, hot-swapping under powered backplanes, and a programmable keep-last-value parameter to maintain safe physical states in the event of a controller stop.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul style=\"list-style-type: square;
