The following illustration shows the circuit diagram for a resistive input.

Guaranteed threshold for monitored voltage OK: > 18 V, guaranteed threshold for monitored voltage faulty: < 14 V.
The following illustration shows the circuit diagram of a relay output (normally open contacts).
The diagram on the following page represents an example of wiring: the module outputs grouped together by the user have a single power supply.
The NC terminals are not wired within the modules, but are used to distribute the power supply neutral to the various loads. For this purpose, use connecting combs, reference
TBX RV 015.
A connecting comb is also used to connect the relay commons (C8.9, C10.11,...) with the supply phase.
The following diagram illustrates the wiring of the terminal.
NOTE: the
-SV terminal and the -IS (0 V) terminal must be connected together.
