Terminal Assignment for Relays and Actuators
N
Connection of external relays. Each
analog output can be connected to an
external relay which has similar data to
the relays described under the U.S. and
European Specifications chapter.
The impedance of the relay must be a
min. of 500
Ω
for an output voltage of
11 V; an impedance of less than 500
Ω
can cause erroneous output voltage.
The output current is limited up to max.
20 mA.
O
Type of connector for actuators with
standard input signal 0 to 20 mA, but the
sensor input impedance must be 500
Ω
.
Each channel can be used as an analog
output 0 to 10 V, or, respectively, as
current output 0 to 20 mA with an external
500
Ω
impedance.
The outputs are protected against over-
voltage and overload 24 Vac.
