FUNCTIONAL DESCRIPTION:
IS200TRLYH1E is a Simplex Contact Output Terminal Board manufactured by General Electric as part of the Mark VIe Series used in gas turbine control systems. The Simplex Contact Output Terminal Board is an I/O interface module designed for GE Distributed Control Systems (DCS). It provides isolated relay contact outputs for discrete control signals, supporting both Normally Open (NO) and Normally Closed (NC) configurations. Each output channel is electrically isolated from the control logic, ensuring protection of the system from field-side voltage transients.
The board is compatible with Simplex I/O modules and integrates directly with Mark VIe DCS platforms. It is mounted on DIN rails, with terminal strips clearly labeled for each output channel to facilitate organized wiring. Typical applications include turbine trip and interlock circuits, alarm annunciation, and auxiliary device control. LED indicators (if present) allow real-time monitoring of output states. The board is designed to handle standard industrial signal levels and conforms to DCS voltage and current ratings.
OPERATION:
The Simplex Contact Output Terminal Board functions as an interface between the control system and external field devices by converting discrete digital signals from Simplex I/O modules into isolated relay outputs. Each output channel responds to logic commands, activating or deactivating connected relays, alarms, or indicators in accordance with the programmed system logic. This allows precise and reliable control of field devices in turbine, generator, and industrial automation applications.
LED indicators, when provided, offer real-time feedback on the status of each output channel, facilitating troubleshooting, diagnostics, and verification of correct operation. The electrical isolation of the outputs safeguards the control logic from voltage transients, short circuits, and other disturbances originating from the field devices, ensuring safe and stable system performance under all operating conditions.
COMPATIBILITY:
The Simplex Contact Output Terminal Board is fully compatible with Simplex I/O modules and integrates seamlessly with Mark VIe Distributed Control Systems (DCS). It supports discrete output applications, including turbine trip and interlock circuits, alarm annunciation systems, and auxiliary device control. The board is designed to interface reliably with field devices such as relays, indicators, and alarms while maintaining electrical isolation, ensuring consistent performance across industrial automation and process control environments.
It adheres to standard industrial signal levels and voltage/current ratings specified for Simplex I/O modules, allowing flexible deployment in diverse DCS configurations. Its compatibility with existing Mark VIe systems enables easy retrofitting or expansion of control panels without requiring modifications to the control logic or system architecture.
