IS200TTURH1CCC | New Surplus GE TTUR PCB

Description

Product Introduction (Anti-Template)

The triple-C suffix on this universal temperature board represents the absolute pinnacle of GE’s temperature input technology—combining full channel isolation with the highest-grade components and factory calibration for unmatched accuracy across both RTD and thermocouple sensors, even in challenging grounding environments. The IS200TTURH1CCC 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, noise immunity, and long-term stability.

What does the ‘CCC’ deliver beyond the standard ‘C’? The isolation uses premium-grade components with higher common-mode rejection and lower leakage. The RTD excitation uses the highest-grade current source components with laser-trimmed accuracy. The cold junction compensation uses a premium reference with individual factory calibration. Gold-plated contacts are standard. Compared to the standard TTURH1C, the ‘CCC’ offers about 20% better isolation performance and significantly better long-term stability across both sensor types. This is the board for critical temperature monitoring where both accuracy and noise immunity are non-negotiable.

Frequently Asked Questions (FAQ)

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

A: Four key upgrades. First, premium galvanic isolation components with enhanced common-mode rejection. Second, flagship RTD excitation with laser-trimmed accuracy. Third, factory-calibrated cold junction compensation per board. Fourth, gold-plated contacts. These add up to the best accuracy, noise immunity, and long-term stability GE offers.

Q: Is the TTURH1CCC worth the premium over the standard C?

A: If you have mission-critical temperature monitoring with mixed sensor types in challenging grounding environments, yes. The premium isolation and factory calibration give you unmatched confidence in your readings. For standard monitoring in clean grounding environments, the ‘C’ is sufficient.

Q: Can I replace a TTURH1C board with a CCC without any changes?

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

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

A: The ‘CCC’ 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 TTURH1CCC?

A: Flagship temperature input protocol with isolation verification. First, visual inspection—look for gold-plated contacts and premium isolation components. Second, verify jumper settings. Third, simulate temperatures for both RTD and thermocouple channels—accuracy should exceed standard ‘C’. Fourth, test isolation by applying common-mode voltage—a genuine ‘CCC’ should reject more than standard ‘C’. Fifth, run a 72-hour stability test at 50°C ambient.

Q: Is the TTURH1CCC 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 TTURH1CCC?

A: Look for the gold-plated contacts and factory calibration markings. Weigh the board; should be about 370 grams. Look for the GE holographic security label. Test the isolation performance—a genuine ‘CCC’ should outperform the standard ‘C’ in common-mode rejection.

Q: What’s the expected lifespan of the TTURH1CCC?

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 variants.

Q: Where do I find the official wiring diagram for the TTURH1CCC?

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