8. Connection
a) Voltage/current supply
The precise contact assignment can be found in chapter 7. The control module can be
operated either with 12 V/DC, 24 V/DC or 12 V/AC. There are separate inputs available
for this:
12 V/DC:
Terminal 1 = +12 V/DC
Terminal 2 = GND
24 V/DC
Terminal 3 = +24 V/DC
Terminal 2 = GND
12 V/AC
Terminal 1 = +12 V/AC
Terminal 2 = 12 V/AC
Never swap these connections, since the product will otherwise be damaged;
loss of warranty/guarantee!
The concurrent connection of several operating voltages (e.g. 12 V/DC and
24 V/DC) is not possible!
The product has a power intake of less than 50 mA in regular reading mode, and about
75 mA when switching the relay.
b) Relay Output
The relay output (terminals 4, 5, 6, see chapter 7) is potential-free. The connection data
of the relay can be found in the chapter on „Technical Data“.
Never switch the mains voltage across the relay!
