GE IS420YDOAS1B Mark VIe Discrete Output Module
Product Overview
The GE IS420YDOAS1B is a high-reliability discrete output module designed for GE’s Mark VIe distributed control system, specializing in mission-critical industrial applications such as gas turbines, steam turbines, and marine propulsion systems. As part of the Innovation Series, this module serves as a vital component for managing automated drive assemblies, valve control, and safety interlocks, ensuring precise and timely actuation of field devices in harsh environments.
Engineered with a protective outer chassis and conformal coating, the IS420YDOAS1B withstands extreme temperatures (-40°C to +70°C), vibration, and humidity, making it suitable for offshore platforms, desert power plants, and chemical processing facilities 3. It interfaces seamlessly with GE’s Speedtronic control system, delivering 24 V DC output signals to drive solenoids, relays, and motors. The module supports hot-swappable operation, allowing maintenance without system downtime—a critical feature for 24/7 industrial operations.
With 16 isolated output channels, the IS420YDOAS1B ensures fail-safe operation by providing galvanic isolation between the control system and field devices. Its diagnostic capabilities include channel-level fault detection, which alerts operators to open circuits or shorted outputs via front-panel LEDs. By integrating with IONet industrial Ethernet switches (e.g., IS420ESWBH1A) and VME-based I/O modules, the IS420YDOAS1B forms a robust control loop that enhances operational efficiency and reduces lifecycle costs.

Enhanced Safety and Diagnostics:
Galvanic isolation (2,500 Vrms) prevents ground loops and voltage spikes from damaging the control system. Front-panel LEDs provide real-time status monitoring, while built-in self-tests (BIST) detect open circuits or shorted outputs, reducing mean time to repair (MTTR) 3.
