Product Description

Overview

The GE IS200STAOH2AAA (IS230SNAOH2A) is a Simplex Analog Output Terminal Board designed for GE’s Mark VIe Control System. It provides the essential interface between digital control modules and physical actuators or devices, enabling precise analog control in industrial turbines, power plants, and complex process systems.

This terminal board pairs with the IS230SNAOH2A module, forming a complete analog output assembly for high-reliability signal transmission to field devices.

Technical Description

The IS200STAOH2AAA is the field-facing connection point for analog outputs. Its compact design simplifies wiring while maintaining signal integrity.

• System Compatibility: GE Mark VIe and Mark VIeS series control architectures.

• Signal Types: Supports standard 0–20 mA and 4–20 mA analog output loops.

• Connectivity: Two barrier-type terminal blocks for secure field wiring and a D-sub connector for interface with the I/O pack.

• Modular Integration: Works seamlessly with PAOCH1B or other compatible analog output modules.

Performance Characteristics

• High Precision: Utilizes high-resolution DACs in the paired I/O pack for exact analog control.

• Loop Monitoring: Detects open circuits, high-resistance connections, and ensures the actual output matches the command signal.

• Electrical Protection: Galvanic isolation safeguards control electronics from surges or ground faults.

• Hot-Swappable Capability: Compatible I/O packs can be replaced without shutting down the system in simplex configurations.

• Environmental Hardening: Operates reliably in elevated temperatures and resists corrosion typical of turbine and power plant environments.

Component Comparison

Note: The "Simplex" designation indicates this setup is for single-path output where redundancy is not required.

Applications

• Actuator Control: Fuel, water, or steam valves.

• Motor Drives: Setpoints for variable speed drives.

• Instrumentation: Analog metering or recording in control rooms.

• Industrial Power Systems: Gas, steam, and wind turbine control loops.

• Process Facilities: Desalination plants, gas compression, and balance-of-plant operations.

FAQ

Q: What is the primary function of the IS200STAOH2AAA?
A: It serves as the terminal board for analog outputs, providing a reliable interface between field wiring and the active I/O module.

Q: Can this board handle 4–20 mA signals?
A: Yes, it supports standard 0–20 mA and 4–20 mA control loops.

Q: Is this suitable for redundant applications?
A: No, this board is simplex only. Redundancy requires a different configuration with TMR-capable modules.

Q: Which I/O pack pairs with this board?
A: Typically, the IS230SNAOH2A or PAOCH1B analog output modules.
