I/O module AI overvoltage

What does 7086 mean?

An overvoltage condition has been detected on an Analog Input (AI) of an I/O module. The AI automatically switches to voltage mode from mA mode as a protective measure. If the high signal level persists, it could damage the input circuit or lead to inaccurate process feedback.

Complete Troubleshooting Guide

1. 1

   Measure the AI signal levels at the source to ensure they are within the specified input range for the module.

2. 2

   Check for incorrect wiring or signal conditioning issues that could lead to excessive voltage on the input.

3. 3

   Verify the AI module's configuration to ensure the correct input type (voltage/current) and range are selected.
