This heavy-duty hardware component provides the direct physical marshalling interface for discrete field devices, capturing states from pressure switches, limit switches, and auxiliary relay contacts across the plant. It accepts dry contact inputs, filters external electrical noise, and routes clean digital telemetry directly to the VTCI processor board inside the VME card cage. Installing this Brand New, original GE terminal board guarantees crisp, bounce-free state transitions and eliminates intermittent sequence-of-events (SOE) logging errors.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cp\u003eThe table below specifies the mechanical layout, channel density, and electrical thresholds of the
