4.4.2.3. Relay interface.
•
The UPS has, as an option, a relay interface card that pro-
vides digital signals in the form of potential-free contacts,
with a maximum applicable voltage and current of 240 V AC
or 30 V DC and 1A.
•
This communication port enables dialogue between the
device and other machines or devices through the relays
supplied in the terminal block arranged on the same card,
with a single common terminal for all of them.
From the factory, all contacts are normally open and can be
changed one by one, as indicated in the information sup-
plied with the optional extra.
•
The most common use of these types of ports is to provide
the necessary information to the file-closing software.
