Description:

The IS200TRPGH1B is a Primary Trip Terminal Board manufactured and designed by General Electric as part of the Mark VI Series used in gas turbine control systems. The I/O controller regulates the TRPG terminal board. Three voting circuits in TRPG feature nine magnetic relays that connect to three trip solenoids, or Electrical Trip Devices (ETD). The primary and emergency sides of the interface to the ETDs are formed by the TRPG and TREG working together. For gas turbine applications, TRPG also accepts inputs from eight Geiger-Mueller flame detectors.

The TRPG diagnostics are run by the I/O board. These include feedback from the trip solenoid relay driver and contact, the solenoid power bus, and the excitation voltage for the flame detector being too low or excessive. If any of the signals becomes abnormal, a diagnostic warning is generated (beyond limits). The terminal board's connectors JR1, JS1, and JT1 each have their own ID device that the I/O board queries. If a discrepancy is found, a hardware incompatibility fault is generated. The terminal board serial number, board type, revision number, and plug location are all encoded on the read-only ID device chip.

The IS200TRPGH1B module serves as the primary trip termination board within the GE Mark VI Speedtronic gas turbine control system. Its primary function is to interface with the primary turbine protection controller and Emergency Trip Devices (ETDs), ensuring swift and accurate responses in emergency trip scenarios. Key features of the IS200TRPGH1B include two large black terminal blocks located on the left side, each equipped with 24 silver metal terminals numbered sequentially from 1 to 48. The bottom half of the board houses a variety of capacitors: a vertical line of 8 solid yellow capacitors centered at the bottom, accompanied by two parallel rows of small white capacitors totaling 16 units to the left.

The IS200TRPGH1B is a PCB or printed circuit board with a variety of different components. Two large black terminal blocks are featured on the left side of the IS200TRPGH1B. Both of these terminal blocks contain twenty-four silver metal terminals which are numbered from one through twenty-four and twenty-five through forty-eight. A variety of capacitors are located on the bottom half of the IS200TRPGH1B. A vertical line of eight solid yellow capacitors is arranged at the bottom of the IS200TRPGH1B in the center of the board. To the left of these yellow capacitors, there are two vertical rows of small white capacitors.
