Features:
- Certified for Hazardous Locations Without Additional Enclosures
- Wide Ambient Temperature Range for Extreme Environments
- Intrinsic Safety 'ic' Protection for Simple Apparatus Connection
The General Electric IS220PDOAH1A carries ATEX Zone 2, Class I Division 2, and IIC gas group certifications. This allows direct installation in turbine auxiliary rooms and compressor stations where explosive gas atmospheres may occur, provided the module is housed in a basic IP54 tool-accessible enclosure – no expensive explosion-proof housings are required.
Rated for operation from -40°C to +70°C, the General Electric IS220PDOAH1A performs reliably in unheated turbine enclosures located in arctic regions, deserts, or offshore platforms. This eliminates the need for cabinet air conditioning or heating in most installations.
The General Electric IS220PDOAH1A is assessed as an associated apparatus with intrinsic safety 'ic' protection level. It can be connected to simple resistive devices (such as relay contacts or switches) located in Zone 2 hazardous areas, provided the field wiring entity parameters (Ca, La, Lo) are respected per GEH-6725R specifications.
The IS220PDOAH1A General Electric Discrete Output I/O Pack may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

- Gas Turbine Control Systems – Provides discrete output actuation for trip solenoids, start-up permissives, and valve positioning within GE Mark VIe based installations.
- Steam Turbine Auxiliaries – Controls lubrication oil pumps, drain valves, and extraction steam actuators in combined-cycle power plants.
- Compressor Stations (Oil & Gas) – Drives anti-surge recycle valves and blow-down solenoids in natural gas transmission facilities requiring ATEX Zone 2 certification.
- Emergency Shutdown Logic – Supports safety-related discrete outputs when incorporated into an appropriately architected control system with properly rated terminal boards.
- Status Indication via Local LEDs – The module provides visual status of power, communication, and output states for rapid field troubleshooting without additional tools.
- Infrared Local Serial Port – Allows local diagnostic access using a compatible handheld device, enabling offline module health checks even when network communication is unavailable.
- Feedback Signal Processing – When used with compatible TRLY terminal boards, the module can collect and process feedback signals to verify relay state changes.
- Soft-Start Current Limiting – Integrates current limiting on power-up to protect both the module and the control power supply from inrush current spikes.
- Extended Temperature Range – Rated for -40°C to +70°C ambient, allowing deployment in unheated turbine enclosures, arctic pipelines, or desert solar-thermal plants without active climate control.
- Hazardous Atmosphere Compatibility – Certified for ATEX Zone 2 (IIC T4 Gc) and Class I, Division 2, enabling installation in areas where flammable gases (Group IIC, e.g., hydrogen, acetylene) may be present during abnormal conditions.
- Pollution Degree 2 Enclosures – Designed for environments with non-conductive pollution only. The module must be installed in an enclosure meeting IP54 rating to maintain hazardous location certification.
- Tool-Access Enclosure Requirement – In Zone 2/Division 2 installations, the enclosure must require a tool or key to open, preventing unauthorized access while maintaining safety compliance per NEC, CEC, and ATEX directives.
