Functional Description
The IS200WREAH1ADB operates as an interface board within the Mark VI control system, primarily serving emergency trip and protection logic paths rather than functioning as a general-purpose I/O board:
Signal Routing: Provides structured termination points for discrete signals related to turbine protection, such as trip inputs, overspeed triggers, breaker status, and emergency stop contacts.
Emergency Trip Support: When integrated with PPRA or other protection logic modules, this board carries critical protection paths to ensure reliable shutdown command execution upon detection of unsafe conditions.
Configurable Jumpers: On-board jumpers enable technicians to flexibly adjust signal routing or combinations based on specific safety logic or system layout requirements.
Typical Applications
IS200WREAH1ADB is applied in industrial turbine control and protection devices, including:
Gas Turbine Protection Rack-Provides emergency trip signal routing for Brayton cycle turbines.
Steam Turbine Emergency Shutdown System - Isolates and interfaces high-priority protection contacts.
Redundant Protection Configuration (TMR) - Ensures safety logic continuity in systems employing Triple Modular Redundancy (TMR) technology.
Control Cabinet Terminal Expansion - Consolidates field wiring into manageable interface paths compatible with GE Mark VI bus and logic modules.

Product FAQ – IS200WREAH1ADB

IS200WREAH1ADB
Q1: What role does the IS200WREAH1ADB play in the GE Mark VI system?
A: It primarily functions as a terminal/option interface board, responsible for organizing and routing emergency trip and protection signals between field devices and Mark VI protection logic modules.
Q2: Does this board handle general-purpose I/O like a PLC?
A: No-it is not a general-purpose processing card. Its function is to provide structured terminal connections and routing support for critical protection paths.
Q3: Can this board be used in other control systems?
A: This board is specifically designed for the GE Mark VI turbine control system and associated terminal/option boards. Use outside this system requires rigorous compatibility verification.
Q4: What is the purpose of the jumpers on the board?
A: Jumpers enable configurable signal routing, allowing the board to adapt to specific logic and connection requirements in different turbine protection schemes.
