Description
Product Introduction
The GE IS200EROCH1ADD is a Mark VIe series expansion rack communication module that provides network connectivity for Mark VIe expansion chassis with specific hardware configuration. This I/O pack enables communication between expansion racks and the main control system.
The ADD suffix denotes a specific hardware configuration with unique communication features and diagnostic characteristics. In our field experience, the EROC provides essential communication for expansion rack applications. For facilities requiring expansion rack communication, the EROC provides the necessary solution.

Frequently Asked Questions (FAQ)
Can I hot-swap this IS200EROCH1ADD into a running Mark VIe system?
We strongly advise against it. The EROCH1ADD has shown unpredictable behavior when inserted into a powered backplane. Schedule a controlled outage, de-energize the rack, and swap it during planned maintenance.
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 145,000 hours for the ADD revision. We have seen these units exceed 15 years in field service.
