Here’s a quick reference guide for anyone new to the WAGO 750 Series I/O System. The PDF explains how System Power (5 VDC) and Field Power (typically 24 VDC) work across both 750 Series controllers and fieldbus couplers, showing how each power bus is distributed through the node.
It compares power modules like the 750‑602 and 750‑613—highlighting which ones add field power only and which add both system and field power—and includes simple examples to help you size and select the right module for your application.
