Isolated Ground on 3MIX12 Module
The 3MIX12 mixed I/O module includes an isolated ground system (ISOGND) on pins 5, 10, 12, and
14 of TB1. ISOGND provides a low noise return (ground) for analog inputs and outputs. It is
completely isolated from the other three ground systems. You can optionally enable grounding for
one or both digital outputs on the 3MIX12 through individual settings for each DO in FBxConnect.
When enabled, digital output(s) are internally connected to ISOGND.
