GE IS200AEPAH1A IS200AEPAH1AFD Application I/O Terminal Board

The GE IS200AEPAH1A IS200AEPAH1AFD serves as an application I/O terminal board for the Mark VI series. This board connects field devices directly to the turbine control processor. You will find this unit in many industrial automation systems. General Electric designed this board for the Speedtronic turbine control platform. Its robust construction ensures reliable operation in harsh environments.

Technical Specifications

This board integrates over 155 discrete components onto a multi-layer PCB. Its dimensions measure roughly 9.5 inches wide by 8.0 inches high. The total weight reaches about 0.88 kilograms including the mounting bracket. Twelve 10-pin terminal blocks handle field wiring for discrete sensors. Twenty-four discrete I/O channels bring digital signals into the board. One backplane connector provides power and data paths to the main rack. The design stores up to 350 joules of capacitive energy for stable signal filtering.

Functional Layout and I/O Management

The GE IS200AEPAH1A IS200AEPAH1AFD interfaces directly with field devices and sensors. Each I/O channel includes protection diodes for overvoltage immunity. Moreover, the board filters input noise before passing signals to the processor. This variant includes upgraded filters for better signal integrity and noise rejection. General Electric specifically designed this terminal board for the Mark VI Speedtronic system. You can replace an older board with this unit without changing the rack configuration.

Installation Guidelines and Compatibility

This I/O terminal board mounts directly into a standard Mark VI rack slot. Always disconnect system power before handling the GE IS200AEPAH1A IS200AEPAH1AFD. The board works with existing GE Mark VI backplanes and field sensors. Verify your firmware revision supports this variant. This board maintains backward compatibility with earlier Mark VI versions. Proper installation ensures reliable I/O termination and system integrity.
