Description
GE 187C2107 G 1DV2-A001
It is a logic control board specifically designed for the condenser steam vent valve (CSDV). This valve plays a protective role in the power plant condensing system: when the condenser vacuum deteriorates or the steam pressure is abnormal, the logic board issues a shut-off command to prevent steam leakage or equipment damage.
