6.2 Electrical connection
All the necessary signals for operation are connected to the rear terminals.
The connecting terminals are designed as removable screw-type terminals
with a grid pitch of 5.08 mm. This makes it possible to connect wires of up to
2.5 mm².
6.2.1 Terminal configuration
9-pole connector strip
On the 9-pole connector strip with terminals 1 to 9, the power supply (supply
voltage) of the digital indicator and the two relay outlets of the alarm outputs
are connected.

5-pole connector strip
On the 5-pole connector strip with terminals 10 to 14 the input signal and the
transmitter supply are connected.
Measuring input for standard signals
The input signal is connected to terminals 10 to 12. The DI30 has a voltage
input and a current input, to which most conventional sensors with a standard
signal output can be connected. The measuring input is galvanically isolated
from the power supply (supply voltage) and the transmitter supply.
