Description

The IS200STAOH2AAA is a Simplex Analog Output (STAO) terminal board manufactured by General Electric as part of the Mark VIe Speedtronic control system. This terminal board is designed to interface with the PAOC I/O pack to provide eight channels of analog output, typically used for controlling field devices such as servo valve actuators, fuel flow regulators, and other process control instrumentation.

Features

• Simplex configuration for Mark VIe control systems.
• Provides eight 0-20 mA analog output channels.
• Onboard ID chip for automatic I/O processor recognition and system diagnostics.
• Integrated noise reduction circuitry for enhanced signal integrity.
• High-density Euro-block style terminal connections for secure field wiring.
• Compact design suitable for flat or DIN-rail mounting.

Applications

• Gas and steam turbine control systems (servo valve and fuel flow regulation).
• Wind turbine pitch control and power regulation.
• Gas compression station process control.
• Precise regulation of pressure and temperature in chemical manufacturing circuits.

Technical Specifications

Installation Guidelines

• Ensure the control system power is disconnected before installing or removing the terminal board.
• Mount the board on a standard DIN-rail or flat surface within the control cabinet.
• Use shielded cabling for all analog signal connections to minimize electromagnetic interference (EMI).
• Ensure proper grounding of the terminal board chassis to the cabinet ground bus.
• Verify that the onboard ID chip is properly seated to allow the I/O pack to identify the module during startup.
• Maintain adequate spacing around the module to ensure proper ventilation and cooling.
