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
voltage potentials, an external galvanic connec-
tion between OUT3/4 and U
T
is not permissible
with analog outputs.

RELAY OUTPUTS OUT1...OUT4
Contact type : potential-free changeover contact
Max.contact rating : 500 VA, 250 V, 2A at 48...62 Hz,
resistive load
Min. contact rating : 6V, 1mA DC
Number of electical

(at ~ 250V (resistive load)
Note:
If the relays operate external contactors, these
must be fitted with RC snubber circuits to ma-
nufacturer specifications to prevent excessive
switch-off voltage peaks.
