Description
Product Introduction
The GE IS200GFOIH1ABA is an enhanced general purpose fiber optic I/O module in the Mark VIe GFOI family, providing optical signal input and output capability with diagnostics for Mark VIe control systems. This I/O pack enables fiber optic I/O functionality with advanced diagnostic features for applications requiring noise-immune, long-distance optical communication.
The ABA suffix denotes enhanced features, advanced diagnostics, and specific hardware configuration. In our field experience, the GFOIH1ABA provides superior fiber optic I/O with diagnostic visibility. For facilities requiring fiber optic I/O with enhanced features, the GFOI provides the necessary solution.

Frequently Asked Questions (FAQ)
Can I hot-swap this IS200GFOIH1ABA into a running Mark VIe system?
We strongly advise against it. The GFOIH1ABA has shown unpredictable behavior when inserted into a powered backplane. Schedule a controlled outage, de-energize the rack, and swap it during planned maintenance.
What is the difference between the IS200GFOIH1A and the IS200GFOIH1ABA?
The ABA has enhanced diagnostics, advanced features, and improved performance over the H1A. We can provide specific details for your unit if you contact us with the serial number.
How do I verify this is a genuine GE module?
We source exclusively from GE-authorized liquidations. Our verification includes OEM packaging inspection, serial number cross-check against GE records, and PCB inspection for GE-specific markings.
What is the expected lifespan of this unit?
We see MTBF around 150,000 hours for the ABA revision. We have seen these units exceed 18 years in field service.
