IS200ISBDG1AAA electrical communication card
The GE IS200ISBDG1AAA is a communication card manufactured by GE. Part of the Mark V series of steam turbine control systems, it is a key component of the protection core and main trip circuit. In addition to at least two sets of main trip relays (PTR1 and 2), it has three sets of three emergency trip relays (ETR1 and 2).
In addition, it has four auxiliary control outputs, including electrical locking solenoid valve, oil reset solenoid valve, mechanical locking solenoid valve and oil test solenoid valve.
In addition, the LED is visible from the side view of the board and is equipped with 50-pin connectors (ids JCC and JDD) and three jumpers (ids JP1, JP2 and JP3). These jumpers allow the installer to set configuration values by changing their location.

The GE IS200ISBDG1AAA is mainly used in turbine control systems, especially as part of the Mark V series.
As a key component of the protection core and main trip circuit, it has multiple sets of trip relays and auxiliary control outputs to ensure that turbine trip can be performed safely under specific circumstances, such as relay failure.
Due to its important role in ensuring the stable operation of turbine control systems, GE IS200ISBDG1AAA is widely used in power, energy and other related fields.
