Product Description
The IS200TREGH1BEC is a board component within the Mark VI or Mark VIe Speedtronic system from GE. Both of these systems are used for the management of industrial gas and steam turbines.
The IS200TREGH1BEC is associated with the Emergency Turbine Protection board (VPRO) and helps to provide independent emergency overspeed protection. This system is separate from the main turbine control system and controls trip solenoids using the associated TREG board. This also works in conjunction with a TRPG board. The IS200TREGH1BEC is used to provide the positive side of 125 VDC trip function and the other board the negative side. Either board can provide trip functionality.
The IS200TREGH1BEC has a total of twelve relays on its surface. Nine of these are used to form three groups of three relays that vote upon inputs controlling trip solenoids. These relays have 28 VDC supplied from the VPRO board. Other board components include three (female) d-shell connectors for cable connections, two terminal strips, and several additional female plug connections. The board also has twelve metal oxide varistors, several wire jumpers, as well as integrated circuits and transistors. Components like resistors, diodes, and capacitors are mounted on both the front and rear surfaces of the board.
The IS200TREGH1BEC carries the board id, the GE logo, a barcode, and several other codes for identification. These help the user locate the proper manual or user guide for their particular part. For detailed information regarding the installation or maintenance of the IS200TREGH1BEC, please refer to these publications originally supplied by GE.
