Description
Product Overview
The GE IS220PDIOH1A is a Discrete Input/Output (DIO) Control Board designed for GE’s Mark VIe Speedtronic Turbine Control System, specializing in high-speed digital signal management and interface control for industrial automation and power generation 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., sensors, switches, actuators), enabling real-time monitoring and precise control of discrete signals in mission-critical environments. Its rugged design with conformal coating ensures resistance to moisture, dust, and electromagnetic interference (EMI), making it suitable for offshore wind farms, oil & gas platforms, and high-vibration industrial settings 29.
Featuring 24 digital inputs and 12 relay outputs, the GE IS220PDIOH1A 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 harsh conditions 28.
As part of the Mark VIe HazLoc-certified subseries, the GE IS220PDIOH1A 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 19.

Key Features & Advantages
High-Density Digital Signal Management:
- 24 digital inputs with hardware filtering (4 ms) and 12 relay outputs provide granular control over field devices, supporting applications such as turbine safety interlocks, valve control, and equipment status monitoring. The module’s optical isolation (1500 VAC) ensures immunity to ground loops and voltage spikes 26.
- 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 811.
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 29.
- 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 19.
Scalable System Integration:
- Integrates with GE’s ControlST software for intuitive configuration of I/O mapping, filter settings, and diagnostic thresholds. Supports industry-standard protocols (EtherNet/IP, Modbus TCP) for seamless integration with third-party SCADA systems 26.
- Modular design allows expansion of I/O capacity by daisy-chaining multiple GE IS220PDIOH1A modules, ideal for large-scale power plants or complex industrial automation systems 811.
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 11.
Application Areas
-
Wind Energy Generation:
- Onshore/offshore wind turbines (2MW–6MW class) for blade pitch control, generator synchronization, and emergency shutdown systems. Monitors sensor inputs (e.g., wind speed, blade angle) and actuates relays to adjust turbine operation dynamically 26.
- Hybrid wind-solar systems requiring discrete control of energy storage systems (ESS) and grid interconnection switches.
-
Power Generation & Distribution:
- Gas/steam turbine power plants for turbine safety interlocks, fuel valve control, and generator breaker management. Ensures reliable operation in combined-cycle plants by managing discrete signals from temperature/pressure sensors 811.
- Microgrid applications, regulating power flow between distributed energy resources (DERs) and utility grids.
-
Industrial Automation:
- Manufacturing facilities (e.g., automotive, food processing) for conveyor system control, machine safety interlocks, and quality inspection triggers.
- Oil & gas platforms for wellhead control, pump monitoring, and flare system activation in hazardous zones 911.
