IS220PDOAH1B | GE Fanuc | Discrete Output Pack

Description

IS220PDOAH1B is an RST analog I/O board and discrete output pack from GE Fanuc, part of the Mark V series designed for gas turbine control systems. This board supports comprehensive signal scaling and conditioning for a wide range of analog and discrete signals, including LVDT inputs, servo valve outputs, thermocouple inputs, 4-20 mA inputs and outputs, vibration inputs, relay driver outputs, pulse inputs, voltage inputs, and generator and line signals. A key feature is its ability to control up to twelve relays, enabling precise discrete output management for turbine system components. It uses dedicated connectors for signal routing: the 3PL connector transfers selected signals to the STCA board, while the JE connector facilitates sending and receiving generator and line signals with the TCQC board. Additionally, it scales and conditions 4-20 mA input signals such as compressor stall detection signals and fuel flow pressure signals, ensuring accurate data processing for critical turbine control functions. This component integrates seamlessly with Mark V series I/O cores to support reliable, high-performance gas turbine operation.
