GE IS215UCVEM01A – VMEbus Controller Module (Mark VI Control System)

Description

The GE IS215UCVEH2AF is an enhanced UCVE-series controller, part of the Mark VIe control platform. It integrates high-speed processing, built-in network switching, and secure firmware services for mission-critical turbine and plant automation.
It is often deployed in triple-modular-redundant (TMR) or dual-redundant architectures to ensure maximum uptime.
