GE IS215UCVGH1A Universal Control Variable Generator Module Mark V

The GE IS215UCVGH1A is a Universal Control Variable Generator Module in the Mark VI Speedtronic control system, designed for gas, steam, and balance-of-plant turbine management. As a single-slot board, it features a 650 MHz Intel Celeron processor, 128 MB flash memory, and 128 MB SDRAM, running on the QNX real-time OS to execute turbine application code efficiently.

Equipped with two 10/100BaseTX Ethernet ports, it connects to the UDH via the first port and supports Modbus/EGD on a separate subnet through the second. Integrating with the VME bus, it communicates with I/O boards, syncing with the VCMI board’s clock for precise timing. Its front faceplate includes ports, a reset switch, status LEDs, and a PMC expansion slot, ensuring versatile operation.

Features:
Processing Power: 650 MHz Celeron processor handles up to 100,000 rungs/blocks per second, supporting real-time turbine control logic.

Dual Ethernet Connectivity: Two ports enable UDH communication and isolated subnet use, with toolbox-validated configurations on startup.

VME Integration: Communicates via VME bus with I/O boards, exchanging data in simplex/TMR systems.

Robust Hardware: Includes a lithium battery, backplane connectors, and components like inductors/resistors; front LEDs indicate operational status.

Mark VI Compatibility: Fits GE Fanuc/Mark VI racks, requiring a cooling fan and for stand-alone setups a VDSK board for power/ID.

Functional Revision: A-rated revision enhances reliability, with “UCVG” in its part number denoting its universal control role and domestic manufacture.
