GE IS200TRLYHIB Relay Terminal Board

GE IS200TRLYHIB Relay Terminal Board

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

Physical Description of the IS200TRLYH1B:

The IS200TRLYH1B contains two (2) large black terminal block on its left edge. Each terminal block features twenty-four (24) metal terminals which are silver. This adds up to a total of forty-eight (48) terminals. Every terminal has been labeled on the terminal blocks in white print. Four (4) connector ports have been placed on the right border of the IS200TRLYH1B. Three (3) of the connector ports are aligned vertically on the edge and the last is sitting parallel to the connector port at the bottom. Near the center of the IS200TRLYH1B there is a long line of relays which are white and black with transparent covers shaped like cubes. These components have been attached to the PCB with black wires. 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.
