Frequency
Connection
for
frequency
based
sensors, with 50 V allowed peak
voltages. Positive terminal is connected
to pin 23 and negative terminal to pin
22.
PS:
Apply recommended grounding to
avoid noise in the frequency signal.
Pt100
Connection for 3-wire Pt100
thermoresistance sensors, with
maximum impedance (cables included)
of 440
Ω. Connect the negative signal
(single wire) to pin 22, the positive
signal (one of the parallel wires) to pin
23 and the line terminal (the other
parallel cable) to pint 24.
This is the
only supported connection mode.
Logic
Connection for dry contact sensors.
Maximum supported voltage is
10 V
.
Positive terminal is connected to pin 23
and the negative terminal to pin 22.
Inverted polarity is not supported.
