IS200VAICH1B | New Surplus GE VAIC PCB

Description

Product Introduction (Anti-Template)

The jump from ‘A’ to ‘B’ on this versatile analog input board is about real-world accuracy across a wider range of signal types and better noise immunity in electrically challenging environments. The IS200VAICH1B is the revision B variant of the VAIC series, designed for configurable analog input signals—voltage, current, thermocouples, and RTDs—with improved signal conditioning that delivers cleaner readings and more stable measurements.

What changed from ‘A’ to ‘B’? The signal conditioning circuitry was upgraded with lower-noise components for better accuracy across all input types—about 15% better noise rejection than the ‘A’. The configuration jumpers were redesigned for clearer labeling and easier setup. The input protection was enhanced for better survival in harsh plant environments. Compared to the VAICH1A, the ‘B’ delivers more stable readings and better accuracy, especially in high-noise cabinet environments. This board is a drop-in replacement for the IS200VAICH1A, with no software changes required.

Frequently Asked Questions (FAQ)

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

A: Three improvements. First, the signal conditioning was upgraded with lower-noise components—about 15% better noise rejection. Second, the configuration jumpers were redesigned with clearer labeling for easier setup. Third, the input protection was enhanced for better survival in harsh environments. These add up to more stable, accurate readings.

Q: Is the VAICH1B worth upgrading from the A revision?

A: If you have noisy cabinet environments or are experiencing unstable readings, yes. The improved noise rejection will give you cleaner, more stable measurements. For clean environments with stable readings, the ‘A’ is still a good board.

Q: Can I replace a VAICH1A board with a VAICH1B without any changes?

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

Q: What types of signals can the ‘B’ handle?

A: The ‘B’ handles voltage inputs (0-10V, ±10V), current inputs (4-20mA), and temperature sensor inputs (thermocouples and RTDs) depending on jumper configuration.

Q: What bench testing should I do before installing a VAICH1B?

A: Standard analog input protocol. First, visual inspection—verify jumper settings. Second, verify continuity. Third, apply known signals and verify measurement accuracy—should be better than the ‘A’. Fourth, test noise rejection by injecting noise on the signal lines. Fifth, run a 24-hour stability test at 50°C ambient.

Q: Is the VAICH1B hot-swappable?

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

Q: How do I verify I’m getting a genuine VAICH1B?

A: Look for the redesigned jumper layout with clearer labeling. Weigh the board; should be about 357 grams. Look for the GE holographic security label.

Q: Where do I find the official wiring diagram for the VAICH1B?

A: GE document GEK-130560 covers the VAIC series. The ‘B’ has identical terminal assignments to the ‘A’. Pay special attention to the jumper configuration table for different signal types. Always cross-reference against your cabinet’s as-built drawings. Verify every channel before terminating.
