Product Overview

The 531X307LTBAJG1 is a dedicated field termination interface board for GE Speedtronic Mark V gas/steam turbine control systems, specially designed to connect linear variable differential transformers (LVDT) and rotary variable differential transformers (RVDT) position feedback sensors used on turbine valve actuators, governor stroke feedback and critical machinery displacement measurement points. It acts as a breakout terminal module to distribute the AC excitation signal from the main control processor to field transducers, then returns the modulated position feedback signal back to the turbine controller for closed-loop valve position regulation and machinery protection monitoring.
