GE IS220PDIOH1B PDIO Discrete Input/Output Module

GE IS220PDIOH1B is a high-performance Parallel Distributed I/O (PDIO) module belonging to the GE Mark VIe Speedtronic turbine control system. 

It serves as a core discrete I/O pack for collecting digital input signals and driving discrete output devices in gas, steam, and wind turbine control applications. 

Equipped with a local processor and dual Ethernet ports, it provides reliable data acquisition and communication for power generation, oil & gas,

 and heavy industrial processes. The module is approved for hazardous locations and works with terminal boards (e.g., ISx0yTDBSH2A, ISx0yTDBTH8A) to expand I/O capacity.
