IS200TTURH1BBB | GE Mark VIe TTUR Universal Temp Board

Description

Product Introduction (Anti-Template)

The triple-B suffix on this universal temperature board represents the absolute pinnacle of GE’s temperature input technology—combining the enhanced ‘B’ platform with the highest-grade components and factory calibration for unmatched accuracy across both RTD and thermocouple sensors. The IS200TTURH1BBB is the flagship variant of the TTUR series, designed for mission-critical temperature monitoring applications where you need to mix RTD and thermocouple sensors with the best possible accuracy and long-term stability.

What does the ‘BBB’ deliver beyond the ‘BAA’ and standard ‘B’? The RTD excitation uses the highest-grade current source components with ultra-low temperature coefficients and laser-trimmed accuracy. The cold junction compensation uses a premium reference with individual factory calibration and thermal tracking. The input filtering uses the best available capacitors with near-zero drift. Gold-plated contacts are standard. Compared to the standard TTURH1B, the ‘BBB’ offers about 30% better long-term stability and significantly tighter initial accuracy across both sensor types. This is the board for critical temperature monitoring where drift is unacceptable.

Frequently Asked Questions (FAQ)

Q: What makes the ‘BBB’ the flagship variant of the TTUR series?

A: Four key upgrades. First, the RTD excitation uses highest-grade current source components with laser-trimmed accuracy and ultra-low temperature coefficients. Second, the cold junction compensation uses a premium reference with individual factory calibration per board. Third, the input filtering uses near-zero drift capacitors. Fourth, gold-plated contacts are standard. These add up to about 30% better long-term stability than the standard ‘B’.

Q: Is the TTURH1BBB worth the premium over the BAA?

A: If you have mission-critical temperature monitoring where long-term drift is unacceptable—bearing temperatures near trip limits, or winding temperatures in large generators—yes. The factory-calibrated CJC and ultralow-drift components give you unmatched confidence in your readings. For standard monitoring, the ‘B’ or ‘BAA’ is sufficient.

Q: Can I replace a TTURH1B board with a BBB without any changes?

A: Yes. The ‘BBB’ is a drop-in replacement. No software changes, no wiring changes, no configuration changes.

Q: What sensor types does the ‘BBB’ support?

A: The ‘BBB’ supports RTDs (Pt100, 3-wire) and thermocouples (J, K, and T types). Each channel is configured via jumpers.

Q: What bench testing should I do before installing a TTURH1BBB?

A: Flagship temperature input protocol with tolerance checks. First, visual inspection—look for gold-plated contacts. Second, verify jumper settings. Third, simulate temperatures for both RTD and thermocouple channels—accuracy should exceed standard ‘B’ specifications. Fourth, run a 72-hour stability test at 50°C ambient to verify ultralow drift.

Q: Is the TTURH1BBB hot-swappable?

A: We advise against hot-swapping temperature input boards. Power down the cabinet segment before swapping.

Q: How do I verify I’m getting a genuine TTURH1BBB?

A: Look for the gold-plated contacts and factory calibration markings. Weigh the board; should be about 366 grams. Look for the GE holographic security label. Test the long-term stability—a genuine ‘BBB’ should outperform the standard ‘B’ by about 30%.

Q: What’s the expected lifespan of the TTURH1BBB?

A: With proper cabinet cooling and clean power, these boards typically run 25+ years. The flagship components and gold-plated contacts extend the life beyond standard and premium variants.

Q: Where do I find the official wiring diagram for the TTURH1BBB?

A: GE document GEK-130554 covers the TTUR series. The ‘BBB’ has identical terminal assignments to the ‘B’, ‘BAA’, and ‘A’—the differences are internal component upgrades. Pay special attention to the jumper configuration table. Always cross-reference against your cabinet’s as-built drawings. Verify every channel before terminating.
