Do not connect the inputs/outputs to a 230 V
mains voltage.
Connect the pushbuttons/switches from GND to the
relevant input/output (SO1, etc.).
The maximum cable length between the
pushbutton and the module will differ, depen-
ding on the type of cable used. However, a
length of 50 m should not be exceeded.
If the channels are being used as outputs (and
the HomeMatic central control unit is being used),
please note the following:
-
The output voltage is 0 V or 5 V at an output
impedance of > 330 Ω.
-
The outputs are not suitable for the direct
connection of inductive loads such as relays.
-
A 330 Ω series resistor is integrated for each
output, so an LED can be connected to it
directly.
The bus and the power supply are connected via
plug-in terminals, each with 2 connections per
contact, so additional wiring can be applied here.
The plug-in terminals are suitable for cable cores
