IS200TREGH1BEC

About the IS200TREGH1BEC

• The IS200TREGH1BEC is a board component from General Electric (GE).
• It is part of the Mark VI or Mark VIe Speedtronic system.
• These systems are used for the management of industrial gas and steam turbines.
• The Mark VIe series, to which this specific board may belong, is an upgrade extending applications to wind turbine settings.
• It is one of GE's last-developed Mark series to utilize the patented Speedtronic control system technology (introduced with the Mark I Series in the 1960s).
• Commonly referred to by its functional acronym: TREG.

Hardware Features & Functionality

• Associated with the Emergency Turbine Protection PCB (VPRO).
• Helps provide independent emergency overspeed protection, separate from the main turbine control system.
• Controls trip solenoids using the associated TREG board and works in conjunction with a TRPG board.
• Provides the positive side of 125 VDC trip function, with the other board providing the negative side. Either board can provide trip functionality.
• Features a total of twelve relays on its surface.
  • Nine relays form three groups of three, which vote upon inputs controlling trip solenoids.
  • These relays receive 28 VDC supplied from the VPRO board.
• Other components include:
  • Three (female) d-shell connectors for cable connections.
  • Two terminal strips.
  • Several additional female plug connections.
  • Twelve metal oxide varistors.
  • Several wire jumpers.
  • Integrated circuits and transistors.
  • Resistors, diodes, and capacitors mounted on both front and rear surfaces.

Product Identification & Revision History

• This device is not the originally-manufactured product for its specific Mark VI Series functional role; it is a revision of the IS200TREGH1 parent board.
• Its functional product number serves as a primary source of hardware component and specification information.
• "IS200" series tag: Codes for normal Mark VI Series assembly and domestic original manufacture location.
• "TREG" functional product acronym.
• "H1" series grouping tag: Denotes Conformal PCB coating style and Group one Mark VI Series product grouping.
• Three-fold revision history (indicated by the "BEC" at the end of the part number).
