FAQ & Engineering Selection Guide

How does the AI563 handle electrical interference from nearby VFDs?

The AI563 utilizes floating inputs and a high-attenuation -3 dB filter at 15 kHz to strip high-frequency noise from the signal path.

Can I mix different thermocouple types on the same module?

Yes, the AI563 channels are individually configurable via the Automation Builder software.

What is the recommended wire loop resistance for thermocouple extensions?

For optimal accuracy, ensure the total loop resistance remains below 100 Ohms to minimize signal voltage drop.

Why is there no status LED for the input signals on this module?

The AI563 is designed for high-density eCo racks where status is typically monitored via the CPU's diagnostic buffer or HMI.

Selection Guidance:

If your application requires high-speed thermal transients (sub-100ms), consider the AC500 "S" series. For standard industrial heating and stable process control, the AI563 offers the best price-to-performance ratio in the ABB catalog.
