GE DS200RTBAG3A DS200RTBAG3AHC Relay Terminal Board

Technical Overview of the GE DS200RTBAG3A DS200RTBAG3AHC Relay Terminal Board

This GE DS200RTBAG3A DS200RTBAG3AHC Relay Terminal Board manages high-current field devices directly. It belongs to the GE Mark V series for turbine control systems. This board switches motors, solenoids, and valves without any intermediate relays. Furthermore, its two variants share the same physical layout and terminal assignments.

Relay Configuration and Status Indication

Each relay on the GE DS200RTBAG3A DS200RTBAG3AHC Relay Terminal Board includes a visible state LED. These LEDs let technicians check active circuits without any test meter. The DS200RTBAG3AHC variant uses jumper J2 and J3 for output logic selection. Meanwhile, the base DS200RTBAG3A version maintains fixed default logic.

Installation and Power Connection Steps

Mount this board in any standard 6U rack slot. Connect all 52 terminal points to field devices like valves or contactors. First, supply 115 VAC power to the CPH and CPN stab connectors. After that, attach the ribbon cable to the RPL connector on the LTB board. Finally, verify each relay coil voltage matches your application requirements.

Energy Discharge and Safety Notice

The GE DS200RTBAG3A DS200RTBAG3AHC Relay Terminal Board stores very little energy after power removal. However, you must wait for internal capacitors to discharge fully before handling. This precaution prevents any residual voltage from reaching the terminal points.
