Energy Storage and Protection Performance
The GE IS200TREAS1AED IS210TREAS1AA IS200WREAH1ABB stores sufficient energy for signal conditioning. Its twelve capacitors provide 1,200 µF of total capacitance. This storage filters electrical noise from trip circuits. Furthermore, the suppression diodes clamp voltage spikes, preventing false trips and protecting the rack electronics.
Role Within the Mark VI Protection System
You will typically find the GE IS200TREAS1AED IS210TREAS1AA IS200WREAH1ABB mounted near the turbine emergency trip panel. It connects to the main rack via three shielded ribbon cables. Moreover, this board supports both normally open and normally closed contact inputs. Its twenty-four channels accept wiring from overspeed probes, temperature switches, and manual trip pushbuttons.
Installation and Wiring Guidelines
Use the GE IS200TREAS1AED IS210TREAS1AA IS200WREAH1ABB as a direct replacement for older TREA or WREA revisions. Always verify the trip circuit voltage before connecting any wires. This terminal board requires no external power supply for passive signal paths. It needs no configuration jumpers or special tools. Simply secure the board with four mounting screws and connect your trip circuit wires to the appropriate terminal blocks.
