Product Introduction
-
Brand: GE
-
Series: Mark VIe Discrete I/O Modules
-
Model: IS220PDOAH1B
-
Product Type: Isolated Discrete Output I/O Pack
-
Description: The IS220PDOAH1B is a high-reliability isolated discrete output module designed for Mark VIe control systems. It is used to switch or control field devices such as relays, solenoids, valves, and motor starters in industrial automation, turbine control, and power generation applications. The module provides individual channel isolation to prevent signal interference and is suitable for hazardous and heavy-duty environments.
