We recommend connecting LEVEL SWITCH 8110 in such a way that
the switching circuit is open when there is a level signal, line break or
failure (safe condition).
Warning:
The instrument must not be operated without an intermediately
connected load, because the electronics would be destroyed if con-
nected directly to the mains. It is not suitable for connection to low
voltage PLC inputs.
Examples for typical applications:
•
Load resistance at 24 V DC: 88 ... 1800 Ω
•
Rated power, relay 253 V AC: > 2.5 VA
•
Rated power, relay 24 V AC: > 0.5 VA
For direct control of relays, contactors, magnet valves, warning lights,
horns etc.
Domestic current is temporarily lowered below 1 mA after switching
off the load so that contactors, whose holding current is lower than
the constant domestic current of the electronics (3 mA), are reliably
switched off.
