IS200TTURH1BAA | GE Mark VIe TTUR Universal Temp Board

Description

Product Introduction (Anti-Template)

The ‘BAA’ suffix on this universal temperature board combines the enhanced accuracy of the ‘B’ revision with premium component selection—delivering the best universal temperature measurement GE offers. The IS200TTURH1BAA is the premium variant of the TTUR series, designed for applications where you need to mix RTD and thermocouple sensors with the best possible accuracy and long-term stability. This board supports both sensor types with jumper-configurable channels, but with premium-grade components that deliver tighter tolerances and longer-term reliability.

What does the ‘BAA’ deliver beyond the standard ‘B’? The RTD excitation uses premium current source components with ultra-low temperature coefficients. The cold junction compensation uses a premium reference with factory calibration. The input filtering uses premium capacitors with better stability over temperature and time. The connector contacts are gold-plated. Compared to the standard TTURH1B, the ‘BAA’ offers about 20% better long-term stability and tighter initial accuracy across both sensor types. This is the board for critical mixed-sensor temperature monitoring where drift is unacceptable.

Frequently Asked Questions (FAQ)

Q: What makes the ‘BAA’ different from the standard ‘B’ revision?

A: Three upgrades. First, the RTD excitation uses premium current source components with ultra-low temperature coefficients. Second, the cold junction compensation uses a premium reference with factory calibration. Third, the connector contacts are gold-plated. These add up to about 20% better long-term stability and tighter initial accuracy.

Q: Is the TTURH1BAA worth the premium over the standard B?

A: If you have critical temperature monitoring points where long-term drift is unacceptable, yes. The premium components and factory calibration give you more confidence in your readings over time. For general monitoring points, the standard ‘B’ is sufficient.

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

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

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

A: The ‘BAA’ 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 TTURH1BAA?

A: Premium temperature input protocol with tighter tolerance checks. First, visual inspection—look for gold-plated contacts. Second, verify jumper settings. Third, simulate temperatures for both RTD and thermocouple channels. Verify accuracy—should be tighter than standard ‘B’. Fourth, run a 48-hour stability test at 50°C ambient to verify long-term drift.

Q: Is the TTURH1BAA 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 TTURH1BAA?

A: Look for the gold-plated contacts. Weigh the board; should be about 364 grams. Look for the GE holographic security label. Test the long-term stability—a genuine ‘BAA’ should outperform the standard ‘B’.

Q: Where do I find the official wiring diagram for the TTURH1BAA?

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