5 Professional FAQs
- What is the difference between simplex and TMR mode on this board?
- Simplex uses one control channel. TMR uses three channels with voting for higher reliability.
- Can I use IS200TTURH1C with older Mark V turbines?
- No. This board works only with Mark VI and Mark VIe systems. Not compatible with earlier Speedtronic versions.
- How do I know if my board needs replacement?
- Look for burned relays, cracked transformers, or failed generator sync. Also check for loose screw terminals.
- Do you sell the PTUR and VTUR boards that work with this terminal board?
- Yes. Please contact us for pricing on PTUR and VTUR boards. We can bundle them together.
- What happens if I set the jumpers incorrectly?
- Wrong jumper setting causes control errors. The generator may not sync properly. Always verify before startup.
Selection Guide – Pick the Right Mark VI Terminal Board
- Step 1 – Identify your turbine control system: IS200TTURH1C fits Mark VI and Mark VIe. Do not buy for Mark V or older.
- Step 2 – Choose simplex or TMR: For critical turbines, pick TMR mode. For smaller or backup units, simplex may be enough.
- Step 3 – Check companion boards needed: You will likely need PTUR and VTUR boards. Order all three together for complete sync control.
- Step 4 – Verify connector types: Your cabinet must have matching D-shell and plug connectors. Adapters may be needed for older racks.
- Pro tip: Take photos of your old board’s jumper settings before removal. This makes installation of the new board much faster.
