This heavy-duty hardware component serves as the primary physical landing and marshalling interface for temperature sensors deployed across gas and steam turbines. It accepts inputs from various thermocouple types, filters environmental electrical noise, and routes accurate temperature telemetry directly to the VTCH processor board inside the VME card cage. Installing this Brand New, original GE terminal board stabilizes critical thermal loop measurements and prevents erratic exhaust over-temperature trips.\u003c\/p\u003e\n\u003ch3\u003eTechnical
