GE DS200TCTSG1A DS200TCTSG1AEE Simplex Trip Board

Key Technical Specifications

This GE DS200TCTSG1A DS200TCTSG1AEE board operates from a 24V DC power supply. It provides four simplex trip relay channels for turbine protection. The unit measures 21 cm in length, 16 cm in width, and 4 cm in height. Its total weight reaches 0.65 kg without any packaging materials.

The GE DS200TCTSG1A DS200TCTSG1AEE includes four safety relay outputs for emergency trips. Additionally, it features one 20-pin ribbon connector for host interface. A single 6-pin terminal block connects the DC power input. The board contains 4 safety relays, 4 status LEDs, 4 snubber circuits, 1 watchdog timer, 12 resistors, and 10 capacitors.

GE DS200TCTSG1A DS200TCTSG1AEE stores energy using one electrolytic capacitor. This capacitor provides 100 µF at 35V rating for relay hold-up. Consequently, the board maintains trip outputs during 25 millisecond power interruptions. Therefore, safety trips remain active through brief voltage dips.

Design and Integration

Both the GE DS200TCTSG1A and DS200TCTSG1AEE versions share identical safety circuit topology. This board uses four-layer PCB construction with force-guided relay contacts for safety compliance. Consequently, the GE DS200TCTSG1A DS200TCTSG1AEE operates reliably from -10°C to +55°C ambient temperature.

For installation, you need M3 screws for the four mounting holes. The board draws 150 mA typical current from the 24V DC supply. Each safety relay includes positive-guided contacts for diagnostic coverage. We recommend using 18 AWG wire for all trip output connections.

Practical Application

This simplex trip board initiates turbine shutdown upon detecting critical faults. It receives trip commands from overspeed and vibration protection systems. The GE DS200TCTSG1A DS200TCTSG1AEE then opens safety relays to de-energize trip solenoids. Therefore, it provides reliable emergency protection for GE turbine control systems.
