Description
Product Overview
The IS215UCVGM06A is a Universal Control Variable Generator Module (UCVG) from General Electric. It belongs to the Mark VI Speedtronic Series for gas and steam turbines. This board runs turbine application code as a single-slot single-board computer. It mounts inside the control module and communicates with I/O boards using the VME bus. The operating system is QNX, a real-time multitasking OS. This device is a revised version of the IS215UCVGM06 parent board. It includes one functional revision (A-rated).

Frequently Asked Questions (FAQ)
What PCB coating does the IS215UCVGM06A use?
This board does not include a specific Mark VI Series surface coating. No conformal coating is applied.
Why does this board have a special assembly version?
The assembly version comes from its base motherboard status. It adopts features from another Mark VI board.
Can I use this board to replace an IS215UCVGM06?
Yes. The IS215UCVGM06A is the A-revision upgrade. It adds one functional revision over the parent board.
What happens if the Lithium battery dies?
The board may lose configuration or real-time clock data. Replace only with the same type 1 Lithium battery.
How do I know if my system needs a simplex or TMR controller?
Simplex works for non-critical processes. TMR is for high-risk turbines requiring voted inputs and output voting hardware.
Which Ethernet port should I use for Modbus?
Use the second Ethernet port. It supports Modbus or private EGD networks. Toolbox configures it separately.
Is the QNX operating system difficult to learn?
No. QNX behaves like a standard multitasking OS. Most turbine engineers find it reliable and easy to use.
Does this board work with 3300 XL 11 mm Proximity Probes?
Yes. The controller processes signals from 3300 XL 11 mm Proximity Probes through compatible I/O boards. Use the VME bus to bring data into the CSDB.
Selection Guide
- Choose the IS215UCVGM06A if you need a single-slot Mark VI controller with Ethernet and QNX.
- Pick this board for new turbine projects or retrofits requiring real-time performance.
- Select simplex for standalone or remote I/O systems.
- Select TMR if you have triple-redundant I/O and need voted inputs.
- Use the first Ethernet port for UDH and peer-to-peer links.
- Use the second Ethernet port only for Modbus or private EGD networks.
- Do not mix rack types. GE Fanuc racks support remote I/O only.
- Always install the required cooling fan. No fan = shorter board life.
- Replace the Lithium battery only with an equivalent type to avoid memory loss.
