IS220YDOAS1AJ | GE Fanuc | Discrete Output Module

Description

IS220YDOAS1AJ is a discrete output module from GE Fanuc, part of the Mark V series designed for gas turbine control systems. As an RST analog I/O board, its core function is to scale and condition a wide range of analog signals read from terminal boards mounted on I/O cores R1, R2, and R3. It supports multiple signal types including LVDT inputs, servo valve outputs, thermocouple inputs, 4-20 mA inputs and outputs, vibration inputs, relay driver outputs, pulse inputs, voltage inputs, as well as generator and line signals. The module features dedicated connectivity: it uses a 3PL connector to write selected signals to STCA boards, and a JE connector to send and receive generator and line signals with TCQC boards. Specifically, it processes 4-20 mA input signals such as compressor stall detection and fuel flow pressure signals, ensuring accurate signal conditioning for critical gas turbine control operations. This high-performance module is engineered for reliable integration into industrial control systems, supporting precise and efficient discrete output control in power generation and heavy industrial applications.
