GE IS220PDOAH1B Discrete Output Module | IS230SNRLH2A Mark VIe

Product Description

Overview

The GE IS220PDOAH1B (IS230SNRLH2A) is a high-performance Discrete Output Module for GE’s Mark VIe and Mark VIeS control systems. Designed for demanding industrial environments, this module converts digital control commands into reliable binary outputs, making it ideal for actuating solenoids, motor starters, and valves in turbines, process plants, and marine propulsion systems.

The combination of the IS220PDOAH1B I/O pack and the IS230SNRLH2A Simplex Relay Terminal Board provides a complete control solution, integrating intelligent processing with secure field connections.

Technical Description

The IS220PDOAH1B serves as the processing core, executing control commands from the Mark VIe controller. It features dual Ethernet ports for redundant IONet communication and a high-speed 32-bit ARM processor with onboard SDRAM and Flash memory.

The IS230SNRLH2A is a simplex relay output board that physically connects to the I/O pack via a DC-37 pin interface. It provides isolated terminal points for wiring relays and supports up to 12 discrete channels. This design eliminates the need for additional cabinet cabling and enhances system reliability.

Performance Characteristics

• High-Speed Control: Activates outputs in <1 ms, ensuring rapid response for critical turbine and process applications.

• Relay & Coil Monitoring: 15 pack inputs allow verification of relay status and coil health, enhancing diagnostic capability.

• Redundant Communication: Dual 10/100 Mbps Ethernet ports maintain connectivity even if one network path fails.

• Electrical Isolation: 500 VDC isolation between channels and to ground protects sensitive electronics.

• Power Flexibility: Dual 28 VDC power inputs with automatic failover ensure continuous operation.

• Environmental Hardening: Rated for –40°C to +70°C and 5–95% non-condensing humidity, suitable for harsh industrial conditions.

• Hot-Swappable Capability: Enables replacement or maintenance without shutting down the system in simplex configuration.

Component Comparison

Note: Simplex configuration is intended for single-path discrete outputs. TMR configurations require different hardware.

Applications

• Solenoid and motor starter control

• Turbine trip and interlock relays

• Valve actuation in power generation and process systems

• Remote signaling and instrumentation

• Marine propulsion and offshore equipment
