DIN-Rail Vegaflex81 Wiring Schematic

I’m replacing an existing probe with a new Vegaflex 81 (4-wire: 2 × power, 2 × data) and need a fresh, installation-ready drawing for the DIN-rail board that houses it. The goal is to guide on-site technicians through a smooth, efficient install while guaranteeing ATEX-zone safety.

Scope of the drawing
The board must show intrinsic safety barriers, surge (parafoudre) protection, fuse protection and the data-reading device, all correctly grouped and earthed for a hazardous area. I have no fixed brand allegiance, so feel free to specify any reliable, standards-compliant components.

Reference material
Photos of the current board are provided; the new layout can mirror the existing footprint where practical.

Deliverables (all required)
• Full schematic, clearly labelled, including every component and terminal reference
• DIN-rail layout drawing that matches the schematic
• Bill of materials with part numbers, ratings and datasheets/links
• Editable source file (AutoCAD, EPLAN, or similar) plus a print-ready PDF

Acceptance criteria
The documents must allow a qualified electrician to wire, test and certify the board without further clarification, meeting ATEX intrinsic safety requirements for the specified probe.
