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 UT (OPTION)

Power: 22 mA / ³ 18 V

As analog outputs OUT3 or OUT4 and trans-

mitter supply U

are connected to different volt-

age potentials, an external galvanic connection

between OUT3/4 and U

is not permissible with

analog outputs.

load)

Note:

If the relays operate external contactors, these

must be fitted with RC snubber circuits to man-

ufacturer specifications to prevent excessive

switch-off voltage peaks.
