The following illustration shows the circuit diagram of a relay output (normally open contacts, outputs 0 to 7).
The following illustration shows the circuit diagram of a relay output (normally closed and normally open contacts, outputs 8 to 11).
The diagram on the following page represents an example of wiring. The module outputs organized into two groups by the user have separate power supplies:
-
outputs 0 to 9,
-
outputs 10 to 11.
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 (C0,1, C2,3,...) with the supply phase.
NOTE: the 8 outputs 0 to 7 are relay outputs with one N/O contact.
The 4 outputs 8 to 11 are relay outputs with a one N/O contact and one N/C contact.
The following diagram illustrates the wiring of the terminal.
