Nominal voltage 24 V DC external
Current sink (IEC 1131 type 1)
Logic “0”
-3...5 V
Logic “1” 15...30 V
Current requirement approx.. 5 mA
TRANSMITTER SUPPLY U

(OPTION)
Power: 22 mA /
³ 18 V
As analog outputs OUT3 or OUT4 and trans-
mitter supply U
T
are connected to different volt-
age potentials, an external galvanic connection
between OUT3/4 and U
T
is not permissible with
analog outputs.

Note:
If the relays operate external contactors, these
must be fitted with RC sn
ubber circuits to man-
ufacturer specifications to prevent excessive
switch-off voltage peaks.
