Features:
- 8 relay outputs rated 5A/250VAC with 2500V isolation for direct trip solenoid control
- TMR (Triple Modular Redundancy) support with overspeed/acceleration/deceleration protection functions
- Wide -40°C to +70°C operation with IONet Ethernet communication and CE/ISO certification
The IS220YPROS1AJ provides 8 discrete relay output channels, each rated for 5A at 250 VAC or 5A at 30 VDC . This high current rating allows the module to directly drive emergency trip solenoids, bypass valves, and alarm annunciators without requiring external interposing relays, simplifying the safety circuit design and reducing potential failure points.
Designed for fail-safe operation, the IS220YPROS1AJ supports Triple Modular Redundancy (TMR) configurations, often using three modules in a 2oo3 (two-out-of-three) voting arrangement . This architecture eliminates single points of failure: if one module fails or produces a spurious trip command, the other two healthy modules override it, preventing costly unplanned turbine shutdowns.
The IS220YPROS1AJ is engineered for extreme industrial environments, operating reliably across a wide ambient temperature range of -40°C to +70°C . This allows installation in unheated turbine enclosures, outdoor skids in arctic climates, or desert power plants without requiring climate-controlled cabinets. The module utilizes IONet, GE's proprietary high-speed Ethernet network, for deterministic communication with the Mark VIe controller .
The IS220YPROS1AJ GE I/O Module may still be available for purchase and support from Apter Power beyond
End-Of-Life (EOL) by the manufacturer (OEM).

- Heavy-Duty Gas & Steam Turbines: Provides independent emergency protection for large GE OEM gas and steam turbines used in power generation.
- Aeroderivative Gas Turbines: Monitors quick-start, high-performance aeroderivative turbine systems utilizing specialized terminal boards like the IS200TREAS1A.
- Emergency Trip Systems (ETS): Serves as the core core safety mechanism in a Safety Instrumented System (SIS) to handle absolute fail-safe trip signals.
- Emergency Overspeed Protection: Continuously reads magnetic speed pickups to calculate precise shaft acceleration and triggers trip relays instantly if limits are breached.
- Emergency Stop (E-Stop): Directly interfaces with hardwired emergency pushbuttons to bypass software logic for immediate machine shutdown.
- Generator Synchronization Check: Monitors bus and generator voltages/frequencies to safely oversee circuit breaker closing.
- Terminal Board Mating: The module mounts directly onto a companion terminal board (such as IS200SPROS1A or IS200TPROS1C) via a high-density D-type connector. It is secured mechanically using integrated mounting screws.
- Network Connectivity: Features two RJ45 Ethernet ports to connect directly to the dual/triple redundant safety IONet fabric.
- Power Supply: Receives its 28 V DC control power directly through the terminal board connection infrastructure.
