GE DS200TCRAG1A DS200TCRAG1AAA Relay Output Board

Key Technical Specifications

This GE DS200TCRAG1A DS200TCRAG1AAA board operates from a 24V DC coil supply. It switches 16 independent relay channels at 240V AC or 30V DC. Each channel handles 8A continuous resistive load current. The unit measures 25 cm in length, 18 cm in width, and 4.5 cm in height. Its total weight reaches 0.85 kg without any packaging materials.

The GE DS200TCRAG1A DS200TCRAG1AAA includes 16 SPDT relays with form C contacts. Additionally, it features 16 LED indicators for visual channel status. A single 34-pin terminal block connects all field wiring. The board contains 16 relays, 16 LED drivers, 16 snubber diodes, 1 optocoupler, and 24 resistors.

Energy Storage	220 µF at 35V

GE DS200TCRAG1A DS200TCRAG1AAA stores energy using two electrolytic capacitors. Together, they provide 220 µF at 35V rating for coil hold-up during switching. This energy storage maintains relay closure through 25 millisecond power interruptions. Therefore, the board prevents unintended contact chatter in noisy industrial environments.

Design and Integration

Both the GE DS200TCRAG1A and DS200TCRAG1AAA versions share identical relay driver circuitry. These boards use four-layer PCB construction with clear relay isolation zones for safety. Consequently, the GE DS200TCRAG1A DS200TCRAG1AAA operates reliably from -10°C to +55°C ambient temperature.

For installation, you need M3 screws for the four mounting holes. The board draws 400 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 output board switches solenoids, contactors, and alarms in industrial control systems. It receives low-voltage commands from a PLC or turbine controller. The GE DS200TCRAG1A DS200TCRAG1AAA then isolates control logic from high-power field devices. Therefore, it provides reliable output expansion for GE drive and turbine control panels
