GE IS200WREAS1ADB Mark VIe Relay Output Module
Product Overview
The GE IS200WREAS1ADB is a high-reliability Relay Output Module designed as a critical component of GE’s Mark VIe distributed control system (DCS), catering to industrial automation and machinery protection applications. Engineered to convert digital control signals into electrical relay outputs, this module enables precise switching of external devices such as valves, motors, and alarms in power generation, oil & gas, and manufacturing environments. As part of the IS200 Series for Mark VIe systems, the IS200WREAS1ADB integrates seamlessly with other Mark VIe modules (e.g., CPU, analog input modules), forming a robust control ecosystem for mission-critical processes.
Featuring a rugged industrial design, the GE IS200WREAS1ADB supports 16 isolated relay output channels, each capable of switching 24 V DC or 120 V AC loads up to 5 A. Its hermetically sealed relays and transient suppression circuitry protect against voltage spikes, ensuring reliable operation in harsh environments with temperature ranges from -40°C to +85°C. The module’s LED indicators provide real-time status feedback for each channel, simplifying troubleshooting and maintenance. With hot-swappable functionality, the IS200WREAS1ADB allows module replacement without powering down the system, minimizing downtime in 24/7 industrial operations.
In automation systems, the IS200WREAS1ADB serves as the interface between the Mark VIe controller and field devices, translating control logic into physical actions. Its compatibility with GE’s Proficy software suite enables remote configuration and monitoring, while built-in diagnostic features enhance system visibility. By combining high-density relay outputs with advanced fault tolerance, this module ensures reliable control in applications where safety and efficiency are paramount, such as turbine shutdown systems, process interlocks, and emergency response mechanisms.

Key Features and Advantages
High-Density Relay Switching: The IS200WREAS1ADB supports 16 independent relay channels in a compact form factor, maximizing space efficiency in control panels. This density is ideal for applications requiring multiple discrete outputs, such as turbine control systems or complex process interlocks.
Robust Electrical Protection: Built-in transient suppression diodes and overcurrent protection safeguard the module and connected devices from voltage spikes and overloads, extending component lifespan and reducing maintenance costs. The hermetically sealed relays prevent contamination, ensuring reliable switching in dusty or humid environments.
Hot-Swap Capability: The module can be replaced while the system is operational, allowing maintenance without interrupting critical processes. This feature is essential for industries where downtime translates to significant losses, such as power generation or oil refining.
Real-Time Diagnostics: LED indicators for each channel provide instant visual feedback on relay status (energized/de-energized), while built-in diagnostic circuitry monitors for open circuits or contact wear. This proactive monitoring reduces troubleshooting time and enhances system availability.
Wide Environmental Tolerance: Engineered to withstand extreme temperatures, vibration, and electromagnetic interference, the IS200WREAS1ADB meets rigorous industrial standards (e.g., IEC 61131-2), making it suitable for harsh environments like offshore platforms or heavy manufacturing facilities.
Seamless System Integration: Compatible with GE’s Mark VIe platform and Proficy programming tools, the module ensures easy integration with existing control systems. Its standardized interface simplifies configuration and reduces engineering time for both new installations and retrofits.
Application Areas
The GE IS200WREAS1ADB is widely deployed in industries requiring reliable discrete control and safety interlocks:
- Power Generation: Controls turbine trip systems, generator circuit breakers, and auxiliary equipment in thermal, hydro, and renewable energy plants, ensuring safe shutdowns and grid stability.
