The GE IS200TRLYH1E is a Relay Terminal Board for the GE Mark VIe (MKVIe) turbine control system. Its main function is to provide a physical interface for relay outputs, operating at 125V, enabling the system to send on/off commands to external devices.
Function and Purpose ⚙️
The IS200TRLYH1E serves as a crucial component for executing control commands from the MKVIe system. It acts as the bridge between the system’s control logic and external relays. When the control system needs to activate or deactivate a piece of equipment, it sends a command to this board. The board’s circuitry then energizes or de-energizes the coil of a relay, which in turn opens or closes the relay’s contacts. This action can control a variety of external devices, such as motors, solenoids, or indicator lights. The 125V rating is a key feature, indicating it is designed for a higher voltage than standard 24V I/O boards, which is common in many industrial control environments. The board provides a secure and organized termination point for the wiring, simplifying installation and maintenance.
Related Components 🤝
The IS200TRLYH1E works in conjunction with other components of the Mark VIe system, including:
- Processor Cards: The main CPU of the system, which executes the control logic.
- I/O Packs: These electronic modules mount directly on the terminal board and contain the active electronics for activating the relays.
- External Relays: The board connects to these external relays, which in turn control the field devices.
