FAQ

1. What is the 3500/04 Earthing I/O Module used for?

It provides a single‑point intrinsically safe earth reference within a 3500 Series protection rack to support internal barrier installations, ensuring proper grounding and safety for transducer systems in hazardous environments.

2. Why is an intrinsically safe earth module needed?

When using internal barriers to protect I.S. sensor circuits, a dedicated earth reference is required to maintain intrinsic

safety compliance and prevent electrical faults or ground loops. This module fulfills that need

 without external hardware.

3. Can I install this in any 3500 rack?

Yes — it is designed to install in a 3500 Series industrial machinery protection rack, but once

 installed, the occupied slot cannot be used for another

monitor module.
