Relays output R1 – R8
The module has eight universal relay outputs. These outputs can adopt one of the two statuses: active or
inactive (the active state means that the voltage has been given to the relay coil). Terminals of relays can
switch over to the following positions:
Figure 5: Relays in active and inactive state
Relays status can be checked by the user interface. Details – see section 3.8.1. Technical specification of
outputs – see section 5.5.
The relay outputs offer various configuration options. Some of them are listed below:
