Description
GE IS220PDOAH1A
- Technical Specifications:
- Series: GE Mark VIe
- Outputs: 12 relay outputs
- Feedback: Accepts feedback from terminal board
- Connectivity: Dual RJ45 Ethernet ports; three-pin power input; DC-37 connector to terminal board
- Relay types: Supports solid-state relays (TRLYH1B/C/D/F) and mechanical relays (TRLYH1E)
- Features: Output enable to keep relays de-energized during startup and self-tests
- Functional Features:
- Designed for simplex, dual, and TMR configurations
- Supports redundant Ethernet connections for high availability
- Includes diagnostics LEDs and infrared port for local serial diagnostics
- Embedded processor board with soft-start power management
- Application Scenarios:
- Discrete output control in gas and steam turbine systems
- Critical safety-related outputs where feedback monitoring is required
- High-availability applications with redundant networks and packs
- Performance Parameters:
- Fast response and reliable output switching
- Supports both mechanical and solid-state relays for flexibility
- Material and Structural Characteristics:
- Industrial-grade housing with robust connectors
- Conformal coating options available
- Designed for direct mounting to terminal boards
- Working Principle:
- The pack receives commands over Ethernet and drives the relay outputs via the DC-37 connector. It monitors feedback signals from the terminal board to verify output status and reports faults. Output enable ensures relays remain off during initialization.
- Installation Requirements:
- Mount securely on compatible TRLY or SRLY terminal boards
- Avoid applying side loads to the DC-37 connector
- Connect Ethernet and power; soft-start allows hot-swapping in many cases
- Configure using ToolboxST
- Usage Notes:
- Choose terminal board and relay type according to application and safety requirements
- Ensure proper grounding and follow field wiring standards
- Use infrared port for local diagnostics when needed
