IS200VATFG1A | New Surplus GE VATF PCB

Description

Product Introduction (Anti-Template)

Temperature monitoring in a turbine comes from a mix of thermocouples and RTDs—and this board gives you the flexibility to handle both on the same termination board. The IS200VATFG1A is the VATF (Versatile Analog Temperature Input) variant for the Mark VIe system, a termination board designed for configurable temperature sensor inputs. This board handles the interface between the Mark VIe controller and either thermocouple or RTD temperature sensors, reducing the need for separate dedicated boards.

The ‘G1A’ designation indicates a specific variant with the ‘A’ revision. The key value of the VATF board is its versatility—each channel can be configured for thermocouple (J, K, or T types) or RTD (typically Pt100) sensors via jumpers. The ‘A’ revision brings improved cold junction compensation for thermocouple mode and better excitation for RTD mode. Compared to the base IS200VATFG1, the ‘A’ offers better accuracy across both sensor types. This board is a drop-in replacement for the IS200VATFG1, with no software changes required.

Frequently Asked Questions (FAQ)

Q: What types of temperature sensors can the VATF board handle?

A: The VATF board can handle both thermocouples (J, K, and T types) and RTDs (typically Pt100 sensors, 3-wire configuration). Each channel is configured via jumpers for the specific sensor type.

Q: What improvements does the ‘A’ revision have over the base VATFG1?

A: The ‘A’ revision has improved cold junction compensation for thermocouple mode and better excitation for RTD mode, resulting in better accuracy across both sensor types.

Q: Can I replace a VATFG1 board with a VATFG1A without any changes?

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

Q: What’s the difference between the VATF and the TTUR boards?

A: Both are versatile temperature input boards. The VATF and TTUR series may have different channel configurations or specific application focuses. Verify compatibility with your specific application before substituting.

Q: Is the VATF board hot-swappable?

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

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

A: Standard temperature input protocol. First, visual inspection—verify jumper settings for your sensor types. Second, verify continuity. Third, for thermocouple channels, use a precision thermocouple simulator. For RTD channels, use precision resistor decade boxes. Verify accuracy at multiple temperature points. Fourth, run a 24-hour stability test at 50°C ambient.

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

A: Check component markings against GE documentation. Weigh the board; should be about 358 grams. Look for the GE holographic security label.

Q: Where do I find the official wiring diagram for the VATFG1A?

A: GE document GEK-130580 covers the VATF series. The G1 variant is detailed in the section specific to that configuration. Pay special attention to the jumper configuration table for different sensor types and thermocouple types. Always cross-reference against your cabinet’s as-built drawings. Verify every channel before terminating.
