4-20 mA HART Loop Protocol & Channel Isolation

The AI‑917‑00 supports mixed current and voltage inputs with shared 0 V reference. While not a dedicated HART interface, its 10‑bit resolution and dual‑processor architecture ensure deterministic acquisition of 4–20 mA loops. Channel isolation is achieved through impedance separation (50 Ω for current, 5.5 kΩ for voltage), minimizing cross‑talk between signal types. Logic pulse outputs are independently driven, preventing interference with analog acquisition.

Frequently Asked Questions

Q: Can the AI‑917‑00 be hot‑swapped? A: No. Removal or insertion under power risks loss of input data and potential damage. Modules should be replaced during system shutdown.

Q: How does the LCD display assist operators? A: The 2‑row LCD provides real‑time input levels, set points, and hysteresis values, enabling quick diagnostics without external tools.

Q: Is RS232 used for live data monitoring? A: No. The RS232 port is strictly for programming and configuration via adapter cable.

Field Installation Guidelines

  • Route current and voltage wiring separately to minimize induced noise.
  • Maintain proper torque on terminal screws to ensure stable compression.
  • Ground shields at a single point to prevent circulating currents.
  • Verify input scaling using a calibrated source before commissioning.
  • Confirm logic pulse output continuity with a loop tester.
