Voltage supply
1
Before connecting the multiplexer, look on the side and
check if the power supply is the same as the connection
value. The power supply will be connected on the terminal
no. 22 and no. 23 (see picture 1).
For devices with direct current, terminal no. 22 is positive
and terminal no. 23 is neutral.
24V DC to be provided by a suitably rated UL Listed Class
2 power supply.
Caution!
The AC-supply devices are isolated from main. A grounded
connection on the low voltage side is required.
In synchronized operation of multiple devices (master/slave),
we recommend installation using short connecting cables.

Transistor output
The multiplexer has one transistor
output per channel (connection
diagram in table 3), switchable as a
PNP- or NPN output. All outputs have
a common plus- (Pin 9) and ground-
connector (Pin 7).
The current capacity is maximal 100
mA with a external voltage between
12 V DC and 30 V DC (see picture 3).
