GE IS220PDOAH1B（IS230SNRLH2A）Discrete Output Module

Configured for discrete output execution in Mark VIe and Mark VIeS turbine control systems, the General Electric IS220PDOAH1B(IS230SNRLH2A) (IS220PDOAH1B(IS230SNRLH2A) Discrete Output Module) provides direct physical/electrical execution.

Suffix Breakdown & Model Matrix

The catalog designation IS220PDOAH1B(IS230SNRLH2A) defines a specific hardware revision and I/O pack pairing. The base identifier IS220PDOAH1B denotes the discrete output module assembly, while the parenthetical IS230SNRLH2A designates the integrated processor and communication I/O pack architecture.

Hardware Specifications

Profinet / EtherNet/IP Deterministic Networks and I/O Density Scaling

The module executes high-performance control tasks across industrial networks while maintaining rigid timing characteristics. Key operational behaviors include:

• Supporting deterministic network communication paths across dual 10/100 Mbps Ethernet (RJ45) ports to maintain synchronized command execution for solenoids, motor starters, and valves.
• Managing I/O density scaling efficiently through a compact, rack-mounted modular architecture equipped with real-time diagnostic capabilities.
• Processing discrete commands with a response time of <10 ms while providing signal isolation of 500 VDC across channel-to-channel and ground boundaries.

Frequently Asked Questions

Q: What power supply architecture does the IS220PDOAH1B(IS230SNRLH2A) utilize for operational redundancy?

A: It features dual 28 VDC power inputs equipped with automatic failover to ensure continuous control power availability.

Q: Does this discrete output module support hot-swapping within the Mark VIe control rack?

A: Yes. The modular rack-mounted design supports unpowered or system-managed hot insertion and extraction when implemented within designated redundant controller topologies.

Field Installation Guidelines

1. Ensure the system rack power supply is completely de-energized and locked out (LOTO) prior to sliding the module into the Mark VIe I/O rack.
2. Verify proper mechanical alignment along the rack guide rails before securing the unit (dimensions 263 mm x 58 mm x 28 mm) to maintain backplane integrity.
3. Terminate dual 28 VDC power feeds and field discrete output wiring securely, ensuring proper signal shielding and grounding up to the 500 VDC isolation rating.
4. Establish dual 10/100 Mbps Ethernet (RJ45) network connections and verify LED diagnostic indicators prior to restoring system power.
