Key Technical Specifications
This GE DS200RTBAG2A DS200RTBAG2AHC relay card operates from a 24V DC coil supply. It switches eight independent relay channels at 240V AC or 30V DC. Each channel handles 8A continuous resistive load current. The unit measures 23 cm in length, 16 cm in width, and 4 cm in height. Its total weight equals 0.7 kg without any packaging materials.
The GE DS200RTBAG2A DS200RTBAG2AHC includes eight SPDT relays with form C contacts. Additionally, it features eight LED indicators for visual channel status. A single 20-pin terminal block connects all field wiring. The board contains 8 relays, 8 LED drivers, 8 snubber diodes, 1 optocoupler, and 16 resistors.

GE DS200RTBAG2A DS200RTBAG2AHC stores energy using one electrolytic capacitor. This capacitor provides 100 µF at 35V rating for coil hold-up during switching. Consequently, the board maintains relay closure through 20 millisecond power interruptions. Therefore, it prevents unintended contact chatter in noisy industrial environments.
Design and Integration
Both the GE DS200RTBAG2A and DS200RTBAG2AHC versions share identical relay driver circuitry. These boards use two-layer PCB construction with clear relay isolation zones for safety. Consequently, the GE DS200RTBAG2A DS200RTBAG2AHC operates reliably from -10°C to +55°C ambient temperature.
For installation, you need M3 screws for the four mounting holes. The board draws 200 mA typical coil current when all relays energize. Each relay includes manual test push buttons for troubleshooting. We recommend using 18 AWG wire for all field output connections.
Practical Application
This relay card module switches pumps, fans, solenoids, and alarms in industrial control systems. It receives low-voltage commands from a PLC or turbine controller. The GE DS200RTBAG2A DS200RTBAG2AHC then isolates control logic from high-power field devices. Therefore, it provides reliable output expansion for GE drive and generator protection panels.
