GE IS200TRLYH2F RELAY OUTPUTS NC, GENERAL ELECTRIC

الوصف

he GE IS200TRLYH2F is a Relay Output Terminal Board for the GE Mark VI (MKVI) turbine control system. Its primary function is to provide a physical interface for relay outputs, specifically using Normally Closed (NC) relay contacts.

Function and Purpose ⚙️

The IS200TRLYH2F serves as a crucial component for executing control commands from the MKVI 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 the coil of a relay, which in turn opens its normally closed contacts. This action can control a variety of external devices, such as motors, solenoids, or indicator lights. The “NC” designation is key, indicating that all the relay contacts on the board are Normally Closed, which is a common configuration for energize-to-trip or de-energize-to-run applications, where a loss of power to the relay will cause the controlled device to perform a safe action. The board provides a secure and organized termination point for the wiring, simplifying installation and maintenance.

Related Components 🤝

The IS200TRLYH2F works in conjunction with other components of the Mark VI 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.
