GE DS200TCEAG1BTF/DS215TCEAG1BZZ01A Emergency Overspeed Board

The GE DS200TCEAG1BTF/DS215TCEAG1BZZ01A board provides critical overspeed protection for turbines. This emergency overspeed board also carries the revision code DS215TCEAG1BZZ01A . It monitors turbine speed using magnetic pickup sensors. The board initiates a fuel trip when speed exceeds safe limits.

Technical Specifications of GE DS200TCEAG1BTF / DS215TCEAG1BZZ01A

Component Count and Board Construction

The GE DS200TCEAG1BTF/DS215TCEAG1BZZ01A board contains over 180 discrete components. You will find three speed input conditioning circuits on the board. Furthermore, the board includes dual microprocessor channels for redundancy. The assembly also features diagnostic LEDs for each channel.

Interfaces, Energy Storage, and Signal Processing

The DS200TCEAG1BTF/DS215TCEAG1BZZ01A revision provides terminal blocks for all speed sensor wiring. Moreover, the board uses capacitors for power hold-up during transients. These capacitors store enough energy for 50 ms of operation. The board also includes relay outputs for emergency trip circuits.

Functional Logic and Application Context

This Mark V board compares each speed input against two independent setpoints. It then votes using two-out-of-three logic for trip decisions. The GE DS200TCEAG1BTF activates the trip relays when any two inputs exceed the limit. Additionally, it provides overspeed test functionality for periodic verification. Consequently, the board ensures reliable emergency shutdowns while preventing false trips.

Installation and Environmental Limits

You must isolate the 28 V DC supply before removing this board. The operating temperature range spans -30°C to +65°C . Furthermore, the board withstands 5 g vibration without relay contact chatter. Always verify the DS215TCEAG1BZZ01A speed settings match your turbine nameplate data.
