The relay outputs provide relays with potential free contacts (see characteristics in page
50).
The status of the relay contacts corresponds to the relay at rest .
The relay contacts are not protected in any way, and therefore they must be installed
externally
as required in the application , taking into account the limitations of the
characteristics of such contacts. In the case of having inductive loads, and to extend the
working life of the relay contacts, it is recommended to use overvoltage protection (VDR
for AC and diodes for DC loads). In all cases a fuse or some kind of protection against
short circuits,
should always be provided according to the needs of the intended load.
