Description
GE IS200TRLYH1BGF Termination Relay Card for Mark VI Turbine Control Systems
The IS200TRLYH1BGF is a termination relay card designed by General Electric (GE) for its Mark VI Speedtronic turbine control platform. This module serves as a critical interface between the control system and external devices, enabling precise relay-based signal switching in industrial applications such as power generation, oil & gas, and water treatment.
The
IS200TRLYH1BGF is engineered to convert digital control signals into physical relay actions, facilitating the operation of motors, solenoids, and other actuators. It features
dual-channel redundancy for fail-safe operation and
programmable logic for custom relay configurations. With
IP54-rated enclosure and EMI/RFI shielding, it withstands harsh environments (temperature range: -40°C to +70°C).
