Circuit board IS200VAICH1C

Circuit board IS200VAICH1C
GE IS200VAICH1C is a circuit board manufactured by GE as part of the Mark V Series of steam turbine control systems and 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.
GE IS200VAICH1C is mainly used in steam 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 IS200VAICH1C has been widely used in power, energy and other related fields.
