Product Overview
The GE IS215UCCCM04A is a UCCC controller board for GE Mark VIe turbine control systems. It serves as a central computing and communications element within the control architecture, executing control applications and exchanging data with distributed I/O and other Mark VIe system components. Secondary technical documentation also identifies the board as a CompactPCI controller designed for GE turbine-control applications.
The GE IS215UCCCM04A belongs to the UCCC M04 configuration and uses a 1.6 GHz Intel Pentium M processor. GE Vernova’s published Mark VIe documentation lists the UCCC with 128 MB DDR memory, 128 MB CompactFlash, five Ethernet ports and QNX 6.5. These specifications are substantially more useful for identification than generic reseller descriptions that incorrectly attribute modern processor architectures to this legacy part.

IS215UCCCM04AB
The GE IS215UCCCM04A is a legacy controller and should be treated as a system-level component rather than a simple plug-in I/O card. Replacement work normally requires attention to the Mark VIe application image, controller configuration, network parameters and software revision in addition to the physical board.
Main Features & Field Considerations
UCCC controller architecture
The UCCC is a processor/controller platform used within GE turbine-control systems. It executes the control application and provides communication between the controller, I/O network and other control-system components.
1.6 GHz Pentium M processor
The M04 UCCC configuration is based on an Intel Pentium M processor operating at 1.6 GHz. This is an important identification point because some current secondary-market pages incorrectly describe the same part number as a modern ARM-based quad-core controller.
Five Ethernet interfaces
GE’s current UCCC comparison specifies five 100 Mbps Ethernet ports. Network-port assignments depend on the installed Mark VIe configuration, so port mapping should be documented before removing an operating controller.
QNX real-time environment
The UCCC platform uses QNX 6.5, supporting the deterministic control environment used by the Mark VIe system.
28 VDC control-system supply
GE’s published specification gives a 28 VDC nominal supply, with an allowable range of 20–36 VDC and maximum power consumption of 50 W for UCCC.
Important Specification Warning
There is substantial misinformation surrounding IS215UCCCM04A on secondary-market websites. One current listing describes this exact part number as a supposed 1.2 GHz quad-core ARM controller with 4 GB DDR4, 8 GB eMMC, USB 3.0 and QNX 7.1. Those specifications conflict directly with GE Vernova’s published UCCC data, which identifies the UCCC as a 1.6 GHz Intel Pentium M platform with 128 MB DDR, 128 MB CompactFlash and QNX 6.5.
For engineering and procurement purposes, I would therefore not use the ARM/DDR4/eMMC specifications for this part.
There is also some inconsistency in secondary sources about whether the board should be called a VME or CompactPCI controller. The more specific identification describes it as a CompactPCI controller board, and GE documentation places the UCCC in the Mark VIe controller family.
Replacement Checklist
Before replacing IS215UCCCM04A, verify:
- Complete part number:
- Functional acronym: UCCC
- M04 configuration
- Hardware revision A
- Processor configuration
- CompactPCI chassis/slot
- Mark VIe software revision
- Controller application backup
- Ethernet-port assignments
- I/O network configuration
- Controller redundancy configuration
- CompactFlash contents
- Network/IP parameters
- Cabinet power supply
- Cooling and airflow
Procurement Description
GE — Mark VIe UCCC CompactPCI Controller / Processor Board, M04 Configuration, Intel Pentium M 1.6 GHz, 128 MB DDR, 128 MB CompactFlash, Five Ethernet Ports, QNX 6.5, 28 VDC Nominal Supply
For a controlled replacement, specify the complete identifier and verify the controller software image, Mark VIe revision, network configuration and installed chassis before commissioning. The exact hardware configuration matters; do not substitute based on generic “UCCC controller” descriptions alone.
