GE DS200TCQAG2B DS200TCQAG2BDC Contractor Driver Board

The GE DS200TCQAG2B DS200TCQAG2BDC serves as a contractor driver board for the Mark V series. This board manages contactor coil activation and deactivation for turbine control. You will find this unit in many industrial power generation systems. General Electric designed this board for the Speedtronic turbine control platform. Its robust construction ensures reliable operation in harsh environments.

Technical Specifications

This board integrates over 130 discrete components onto a multi-layer PCB. Its dimensions measure roughly 8.2 inches wide by 6.8 inches high. The total weight reaches about 0.71 kilograms including the protective cover. Eight contactor output channels drive external contactor coils directly. Four status feedback inputs monitor contactor position for verification. One backplane connector provides power and control paths to the main rack. The design stores up to 330 joules of capacitive energy for stable coil activation.

Functional Layout and Driver Management

The GE DS200TCQAG2B DS200TCQAG2BDC drives contactor coils with high reliability. Each driver transistor switches the coil current on demand from the controller. Moreover, the board includes flyback diodes to suppress voltage spikes. This variant includes upgraded transistors for better current handling and durability. General Electric specifically designed this driver board for the Mark V Speedtronic system. You can replace an older board with this unit without changing the rack configuration.

Installation Guidelines and Compatibility

This contractor driver board mounts directly into a standard Mark V rack slot. Always disconnect system power before handling the GE DS200TCQAG2B DS200TCQAG2BDC. The board works with existing GE Mark V backplanes and contactor assemblies. Verify your firmware revision supports this variant. This board maintains backward compatibility with earlier Mark V versions. Proper installation ensures reliable contactor control and system integrity.
