X3, X4
Connector I²C bus for connecting additional I/O modules and connec-
tion to the display module.
2
S1
DIP switch for setting the address on the I²C bus by means of the
bridge SJ (address 0 … 15 = SJ open, address 16 … 23 = SJ closed)

Digital inputs 1…8 The digital inputs are controlled by voltage signals.
These can be created by an internal or external voltage and potential-
free contacts.

V11…V18
Alarm LEDs, light up when voltage is present at the associated digital in-
put.
