5.7.3.4 Relay outputs
DANGER
Insufficient separation from PELV circuits
Danger to life from electric shock!
▷
When connecting the relay outputs to low voltage or protective extra-low
voltage, ensure sufficient separation from the PELV circuits (double or
reinforced insulation).

Relay contacts
The relay outputs can be wired with either low voltage up to 250 VAC/220 VDC or
protective extra-low voltage (PELV).
The relay outputs are safely isolated from each other and from the PELV circuits of
the digital inputs and analog inputs.
