VEGA VEGAVIB 55 - transistor (NPN-PNP) - Manual (Page 17)

We recommend connecting VEGAVIB 55 in such a way that
the switching circuit is open when there is a level signal, line
break or failure (safe condition).
The instrument is used to control relays, contactors, magnet
valves, warning lights, horns as well as PLC inputs.
