Product Description

Overview

The GE IS220PDIOH1B Digital I/O Pack and IS230TNDSH2A termination board provide reliable digital signal acquisition and output control for Mark VIe turbine systems. This module digitizes input contact signals and drives output devices with high accuracy. Moreover, it integrates diagnostics to detect open or shorted channels, ensuring safe and predictable turbine operation.

Designed for industrial automation, this system handles multiple isolated channels while maintaining secure communication via Ethernet. Therefore, it supports deterministic control in gas turbines, steam turbines, and critical process systems.
