IS200TRLYH1BHH GE Mark VIe, Relay Output Terminal Board

Description:

The IS200TRLYH1BHH is a termination relay card designed for the Mark VI turbine control system, produced by GE. This board represents the "B" revision of the TRLY terminal relay board and includes several key features:

- Voted Coil Drive Feedback
- Socketed Sealed Mechanical Relay
- MOV Suppression
- 48 Barrier Terminals

Physical Description of the IS200TRLYH1BHH:
The IS200TRLYH1BHH features two (2) large black terminal blocks on its left side. Each terminal block houses twenty-four (24) silver metal terminals, totaling forty-eight (48) terminals. These terminals are labeled in white print on the terminal blocks. Four (4) connector ports are located on the right edge of the IS200TRLYH1BHH. Three (3) of these connector ports are arranged vertically along the edge, while the fourth sits parallel to the other three at the bottom.

Centrally positioned on the IS200TRLYH1BHH is a row of relays, which are white and black with transparent covers shaped like cubes. These relays are affixed to the PCB with black wires. Adjacent to each relay is a circular black transistor, and paired with each transistor is a round red MOV or metal oxide varistor. Five (5) relays are aligned vertically on the top half of the IS200TRLYH1BHH, while another five (5) relays are positioned on the PCB's lower half.

Frequently Asked Questions:

1.What types of applications and connectors are supported by the IS200TRLYH1BHH terminal board in conjunction with the PDOA/YDOA I/O pack?
Simplex and TMR applications are supported by the PDOA/YDOA I/O pack when using the TRLY 1B. The terminal board's DC-37 pin connections accept the I/O pack as a plug-in. For simplex systems, connector JA1 is used, while for TMR systems, connectors JR1, JS1, and JT1 are used.

2.How many relay channels on one TRLY1B board?
12（6 relays, with optional solenoid driver voltages；5 relays, with dry contacts only；1 relay, with 7 Ampere rating）
