General Electric IS200TRLYH1BGE Mark VIe Relay Output Board

Description

The IS200TRLYH1BGE functions as a high-performance relay output board manufactured by General Electric as part of the Mark VIe control system platform. It is designed to accommodate 12 plug-in magnetic relays, offering versatile contact signal routing across turbine management architectures. The first six relay channels can be configured via on-board jumpers for dry contacts, Form-C contact outputs, or driving external solenoids. Relays 7 to 11 provide unpowered, isolated Form-C contact configurations, while output 12 serves as a dedicated isolated Form-C contact designed explicitly for unique system operations such as ignition transformers.

Features

• Configurable Power Solutions: Supports individual power sourcing selection for channels 1 through 6, accepting standard 125 V DC, 115/230 V AC, or 24 V DC lines with on-board suppression filters.
• Isolated Contact Routing: Features isolated Form-C contacts on relays 7 through 11 to handle secondary circuit separation.
• Specialized Application Relay: Provides a dedicated isolated Form-C configuration on output 12 optimized for high-demand specialized loads like ignition transformers.
• Individual Overcurrent Protection: Equipped with jumper-selectable fuse slots (FU1 through FU12) to secure individual relay output branches.
• Advanced Contact Sensing: Incorporates jumper groups (JP1 through JP12) to allow selective contact voltage sensing across designated control parameters.

Applications

• Mark VIe steam, gas, and hydro turbine management systems
• Solenoid drive control systems and industrial actuator lines
• Power plant ignition transformer operations

Installation Guidelines

• Terminal Fastening: Secure the two field I/O terminal blocks directly onto the board frame using two screws per block. Ensure wire gauges do not exceed 12 AWG.
• EMI Mitigation: Connect field wiring shields directly to the shield terminal strips located adjacent to each terminal block, keeping them bound securely to the chassis ground.
• Fuse Allocation: For relays 1 to 6 utilizing field power distribution, ensure two appropriate fuses are correctly seated within each corresponding circuit loop (slots FU1 through FU6).
