Key Technical Specifications
This GE IS200TRESH1A IS200TRESH1AAA board operates from a 24V DC power supply. It provides four emergency trip channels for turbine protection systems. The unit measures 20 cm in length, 15 cm in width, and 4 cm in height. Its total weight equals 0.6 kg without any packaging materials.
The GE IS200TRESH1A IS200TRESH1AAA includes four safety relay outputs for trip commands. 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 IS200TRESH1A IS200TRESH1AAA 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 IS200TRESH1A and IS200TRESH1AAA versions share identical safety circuit topology. These boards use four-layer PCB construction with forced-guided relay contacts for safety compliance. Consequently, the GE IS200TRESH1A IS200TRESH1AAA 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 emergency trip board initiates turbine shutdown upon detecting critical faults. It receives trip commands from the overspeed and vibration protection systems. The GE IS200TRESH1A IS200TRESH1AAA then opens safety relays to de-energize trip solenoids. Therefore, it provides reliable emergency protection for GE turbine control systems.
