Product Overview

IS220PHRAH1B is a high-resolution analog input I/O pack for GE Mark VIe turbine control platform. It acquires high-precision process signals from pressure, temperature, flow and position sensors for turbine control loop and protection logic execution. Dual redundant IONet Ethernet interface ensures reliable communication with main controller for safety-critical power generation applications. Widely deployed in combined cycle power plants, refinery turbine trains and industrial power generation facilities. Surplus and refurbished tested spare I/O module for turbine control system maintenance projects.

Application Notes

• Install on matching Mark VIe terminal base assembly.
• Use shielded twisted-pair cable for field analog signal wiring.
• Observe strict ESD anti-static handling during module replacement.
• Typical deployment: Mark VIe high-resolution analog input I/O pack spare-part stocking.
