IS200VAICH1A | 24V Analog Input Termination H1A

Description

Product Introduction (Anti-Template)

Analog input signals come in many flavors—4-20mA, 0-10V, thermocouple, RTD—and this board is designed to handle a versatile mix of them. The IS200VAICH1A is the VAIC (Versatile Analog Input Card) variant for the Mark VIe system, a termination board designed for configurable analog input signals. This board handles the interface between the Mark VIe controller and a variety of analog sensors, making it a flexible solution for diverse I/O requirements.

The ‘H1A’ designation indicates a specific variant with the ‘A’ revision. The key value of the VAIC board is its versatility—each channel can typically be configured for different signal types (voltage, current, or temperature sensors) via jumpers. The ‘A’ revision brings improved signal conditioning and better accuracy. Compared to the base IS200VAICH1, the ‘A’ offers better measurement stability. This board is a drop-in replacement for the IS200VAICH1, with no software changes required.

Key Technical Specifications

Compatible Replacement Models

✅ Drop-in Replacement: IS200VAICH1 — The base revision without the ‘A’ suffix. Identical pinout, mounting, and software interface. The ‘A’ revision has improved signal conditioning and measurement stability. No software changes required.

⚠️ Software Compatible: IS200TBCI1A — General-purpose analog I/O board. Similar functionality but may have different configuration options. Verify compatibility with your specific signals.

⚠️ Software Compatible: IS200TBTCH1A — Thermocouple-specific board. Less versatile—thermocouples only. Requires software reconfiguration.

⚠️ Software Compatible: IS200TRTDH1A — RTD-specific board. Less versatile—RTDs only. Requires software reconfiguration.

❌ Hardware Incompatible: IS200TBQGH1A — Excitation termination board. Different pinout and application.

Frequently Asked Questions (FAQ)

Q: What types of signals can the VAIC board handle?

A: The VAIC board is versatile—it can typically handle voltage inputs (0-10V, ±10V), current inputs (4-20mA), and temperature sensor inputs (thermocouples and RTDs) depending on jumper configuration. This makes it a flexible solution for mixed signal environments.

Q: What improvements does the ‘A’ revision have over the base VAICH1?

A: The ‘A’ revision has improved signal conditioning for better measurement stability and accuracy across all input types.

Q: Can I replace a VAICH1 board with a VAICH1A without any changes?

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

Q: Is the VAIC board hot-swappable?

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

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

A: Standard analog input protocol. First, visual inspection—verify jumper settings for your signal types. Second, verify continuity. Third, apply known signals (voltage, current, or simulated temperature) and verify measurement accuracy. Fourth, run a 24-hour stability test at 50°C ambient.

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

A: Check component markings against GE documentation. Weigh the board; should be about 355 grams. Look for the GE holographic security label.

Q: Where do I find the official wiring diagram for the VAICH1A?

A: GE document GEK-130560 covers the VAIC series. The H1 variant is detailed in the section specific to that configuration. 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.
