IS220PDIAH1A | GE Mark VI IS200 Discrete Contact Input Terminal Board

Product Overview

The IS220PDIAH1A Discrete Input Pack is a modular printed circuit board (PCB) designed by General Electric (GE). It was specifically created for the Mark VI Turbine Control System Series, offering robust integration into automated drive assemblies. The Mark VI series represents a significant upgrade over its predecessor, the Mark V Turbine Control System Series, by adding functionality for wind turbines alongside the traditional gas and steam turbine control environments. Notably, the Mark VI Series is one of the last product lines to incorporate GE’s patented Speedtronic control system technology.

Hardware and Functionality

The IS220PDIAH1A is classified as a Discrete I/O Pack and works in tandem with the YDIA Discrete Input Module in the Mark VI Series. While this particular model is a revision of the original IS220PDIAH1 device, it plays a crucial role in providing discrete input functionality for the system.

Several terminal boards can be used with the IS220PDIAH1A, including:

IS200TBCIH4C
IS200STCIH1A
IS200STCIH8A
IS200TBCIH2C
IS200TCIH2A

These models support hazardous location certifications, such as ULE207685 for non-hazardous environments and UL DEMKO 12 ATEX 1114875X for ATEX Zone 2 Group IIC locations.

The IS220PDIAH1A does not have a faceplate like other Mark VI devices, as it is an I/O pack. However, it includes seven front indicators: power and link status indicators (ENet1 and ENet2), and an Ethernet port for easy communication. The pack complies with UL 60079-15 Ed. 3 and UL 600790 Ed. 5 standards, making it suitable for use in Class I Zone 2 Group IIC environments.
