Description
Product Overview
The GE IS220PDOAH1A is a high-performance Discrete Output (DO) Control Board designed for GE’s Mark VIe Speedtronic Turbine Control System, specializing in precision relay control and real-time signal management for mission-critical industrial applications. As a core component of the Mark VIe ecosystem, this module acts as a bridge between the control system and field devices (e.g., valves, actuators, solenoids), enabling reliable execution of discrete commands in harsh environments such as oil & gas platforms, power plants, and offshore wind farms 16.
Featuring 12 isolated relay outputs with 32 VDC/3.15 A per channel, the GE IS220PDOAH1A supports hot-swappable redundancy (simplex/DMR configurations) and integrates with GE’s ControlST software for programmable logic control and diagnostics. The board interfaces with dual Ethernet ports (10/100 Mbps) and Ionet communication networks, enabling seamless integration with distributed I/O systems and plant-wide SCADA platforms. Its built-in local processor and advanced filtering capabilities (4 ms hardware filtering) ensure accurate signal acquisition and noise reduction, critical for maintaining system reliability in high-vibration or EMI-prone settings 36.
As part of the Mark VIe HazLoc-certified subseries, the GE IS220PDOAH1A is approved for use in hazardous locations when paired with compatible terminal boards (e.g., IS200TDBSH2A or IS200TDBTH2A). This modular design allows for flexible system expansion, supporting up to three redundant modules in Triple Modular Redundancy (TMR) architectures for SIL-rated safety applications 46.

Key Features & Advantages
High-Density Relay Control:
- 12 isolated relay outputs provide granular control over field devices, supporting applications such as turbine safety interlocks, valve actuation, and equipment status monitoring. The module’s optical isolation (1500 VAC) ensures immunity to ground loops and voltage spikes 68.
- Supports hot-swappable redundancy, allowing seamless replacement of faulty modules without system downtime. Redundant Ethernet ports ensure continuous data transmission even in the event of network failures 36.
Rugged Design for Harsh Environments:
- Conformal-coated circuitry and wide temperature range (-40°C to +70°C) enable reliable operation in offshore, desert, and high-altitude environments. EMI shielding minimizes interference from adjacent equipment, ensuring signal integrity in noisy industrial settings 111.
- HazLoc certification (when paired with compatible terminal boards) makes it suitable for explosive gas or dust environments, critical for oil & gas and chemical processing applications 46.
Scalable System Integration:
- Integrates with GE’s ControlST software for intuitive configuration of relay mapping, filter settings, and diagnostic thresholds. Supports industry-standard protocols (EtherNet/IP, Modbus TCP) for seamless integration with third-party SCADA systems 68.
- Modular design allows expansion of output capacity by daisy-chaining multiple GE IS220PDOAH1A modules, ideal for large-scale power plants or complex industrial automation systems 111.
Cost-Effective Maintenance:
- Built-in self-diagnostics and LED indicators simplify fault isolation, reducing mean time to repair (MTTR). GE-certified refurbishment services extend module lifespan, offering a cost-efficient alternative to replacement 36.
