Details
IS200TRPGH1B is a Terminal Board manufactured and produced by GE and it is a part of the Mark VI Series used in gas turbine control systems.
As an 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.
There are two board types as follows:
The H1A and H1B versions include three voting relays built into each trip solenoid for TMR applications.For simplex applications, the H2A and H2B versions have one relay per trip solenoid.
The main protection solenoids are tripped by the main protection relays on TRPG, which are controlled by the I/O board.
In TMR applications, a relay ladder logic two-out-of-three voting circuit is used to vote the three inputs in hardware.
The I/O board keeps track of supply voltages for diagnostic purposes and tracks the current flow in its relay driver control line to determine whether to electrify or de-electrify the relay coil contact status.
The diagnostics check each normally closed contact from a relay on the TRPG board to make sure it is functioning properly.
