Description
1. Product Title
GE IS200VAICH1DAB – Analog Input/Output (VAIC) Module
2. Product Overview
TheIS200VAICH1DAB is a precision analog input/output module designed for GE Mark VI and Mark VIe turbine control systems. Functioning as a high-density analog interface board, it collects continuous analog signals (from field sensors like pressure, temperature, level, and flow transmitters) and accurately converts them into digital data that the control system can process for real-time regulation and monitoring.
This module supports multiple analog signal types and features onboard signal conditioning, multiplexing, and conversion circuitry. It is essential in applications where precise feedback from field instrumentation drives control decisions and safety logic. Engineered for industrial environments, theIS200VAICH1DAB enhances system reliability, simplifies wiring complexity, and delivers high-resolution data to the Mark VI/VIe controller.
