The GE IS200TRLYH1B IS200TRLYH1BGF Terminal Relay Card switches field signals safely in Mark VI control systems. You will find this board in turbine protection panels and generator control cabinets. It provides reliable relay outputs for critical plant operations.
Technical Specifications
The GE IS200TRLYH1B IS200TRLYH1BGF Terminal Relay Card carries its revision code clearly on the front edge. This board measures 267 mm in length and 152 mm in width. Its total height reaches 35 mm including relay housings. The card weighs approximately 0.72 kg (1.59 lbs). Transition words like first and then help explain its switching sequence. First, the board receives low-voltage signals from the main controller. Then, its onboard drivers energize the appropriate relay coils. Finally, each relay switches high-voltage field circuits safely.

Functional Features
The GE IS200TRLYH1B IS200TRLYH1BGF Terminal Relay Card includes a 2200 µF capacitor bank for coil hold-up. This storage ensures relays maintain position during brief power dips. Additionally, each relay has a manual test button for field troubleshooting. Moreover, gold-flash contacts prevent oxidation in high-humidity environments. The card also provides flyback diodes across each coil.
Installation and Compatibility
This board replaces older revisions like IS200TRLYH1A without software changes. Always match the ribbon cable orientation carefully before inserting it. The GE IS200TRLYH1B IS200TRLYH1BGF Terminal Relay Card requires 24V DC from the backplane only. You can mount this card vertically or horizontally in any Mark VI rack.
