Description
🔹 Product Description
The GE General Electric IS215UCVEH2A, with assembly designation IS215UCVEH2AE, is a VME Controller Board for the GE Mark VI Speedtronic turbine control system. The UCVEH2A is a single-board controller that performs control application processing within the Mark VI VME architecture. Available technical references identify the board with an Intel Celeron processor operating at 300 MHz and 32 MB of DRAM.
The controller provides VME backplane connectivity and Ethernet communication for Mark VI control applications. The H2A configuration is associated with a primary 10BaseT/100BaseTX Ethernet interface for Unit Data Highway communication, while the front panel provides status and service interfaces used for controller setup and diagnostics. Exact communication and memory configuration should be verified against the installed board revision before replacement.

🔹 Common Questions & Answers
Q: What is the GE IS215UCVEH2A?
A: It is a UCVE VME Controller Board used as a controller in GE Mark VI Speedtronic systems.
Q: What is IS215UCVEH2AE?
A: IS215UCVEH2AE is the associated assembly/revision designation for the IS215UCVEH2A controller. The complete board marking should be matched when ordering a replacement.
Q: What processor does the UCVEH2A use?
A: Technical references identify an Intel Celeron processor operating at 300 MHz.
Q: How much memory does the board have?
A: The documented UCVEH2A configuration includes 32 MB of DRAM. Some listings also reference onboard flash or CompactFlash storage, so the exact memory configuration should be checked against the board revision.
Q: What operating system does it use?
A: The UCVE controller runs the Mark VI control application under the QNX real-time operating system.
Q: What communication interface does the IS215UCVEH2A provide?
A: The H2A controller uses Ethernet communication, with a documented 10BaseT/100BaseTX RJ-45 interface for Mark VI network functions such as Unit Data Highway communication.
Q: Where is the board installed?
A: It is installed in the VME rack of a GE Mark VI control system and communicates with associated control and I/O hardware through the VME architecture.
Q: Is IS215UCVEH2A the same as IS215UCVEH2AE?
A: They refer to the same basic controller family, with IS215UCVEH2AE representing the more complete assembly/revision designation. Always compare the complete label and revision before replacement.
Q: Can any UCVE board replace the IS215UCVEH2A?
A: No. UCVE variants can differ in hardware configuration and communication interfaces. The complete UCVE generation, hardware variant, suffix, and system architecture should be matched before installation.
Q: What should be checked before ordering?
A: Verify the complete IS215UCVEH2A/IS215UCVEH2AE marking, revision, processor and memory configuration, Ethernet interface, VME rack position, system architecture, and applicable Mark VI configuration or firmware.
