The IS200TRLYH1B is a termination relay card for the Mark VI turbine control system manufactured by GE. This board is the "B" revision of the TRLY terminal relay board and features the following characteristics:
- Voted Coil Drive Feedback
- Socketed Sealed Mechanical Relay
- MOV Suppression
- 48 Barrier Terminals
Hardware Tips and Specifications
The IS200TRLYH1B contains:
- two (2) large black terminal block on its left edge
- each with twenty-four (24) metal terminals which are silver
- four (4) connector ports placed on the right border of the IS200TRLYH1B
- a long line of relays which are white and black with transparent covers shaped like cubes
- on both sides of each relay is a black transistor which is circular
- paired together with every transistor is a round red MOV or metal oxide varistor
Five (5) of these relays are lined up vertically on the top half of the IS200TRLYH1B. Five (5) additional relays have been aligned on the PCB’s lower half.
