Technical data
The power supply for the evaluation unit, depending on model
U
=
24 V DC ± 20 %, ~4,7 W, or
U
=
24 V AC ± 10 %, 50 ... 60 Hz, ~7,5 VA, or
U
=
115 V AC ± 10 %, 50 ... 60 Hz, ~7,5 VA, or
U
=
230 V AC ± 10 %, 50 ... 60 Hz, ~7,5 VA.
The maximum safety voltage is
U
=
33 V at 24 V AC/DC, resp.
m
U
=
130 V at 115 V AC, resp.
m
U
=
253 V at 230 V AC.

The electric circuit of the sensor is designed with "Intrinsic safety" (ia) ignition protection class with a
linear output characteristic. Output values per electric circuit are
Output voltage
Output current
Output power
Internal capacitance
Internal inductance
Permissible external
inductance
capacitance
The intrinsically safe sensor circuits are galvanically isolated from the supply circuit safely up to a peak
crest voltage of 375 V.
As outputs five relays are available each with potential-free relay contacts. The terminal values are:
Alternating current AC
Direct current DC
When an acknowledge button is used it must be potential-free, as the connectors are wired-up to the
power supply!
The evaluation unit can be used in the following ambient temperature range:
T
= -20 °C ... +50 °C
