3.6.8 Relay outputs
The electronics module has a maximum of six
relays, each with a changeover contact. These
switches are assigned various switching tasks
depending on the respective application. The
corresponding diagrams are defined in chap-
ter 9. “Wiring diagrams”.
The connection and switching of non-permis-
sible loads / loads destroys the relay contacts.
The device works uncontrollably as a result!
In order to switch inductive loads or larger
capacitive loads, which exceed the technical
characteristics of the relay contact, an additi-
onal switching element must be installed. For
example a contactor or load relay with suita-
ble specification. Relay contact details see
chapter 3.11 "Technical Data" - Relay outputs.
To protect radio interference suppression, the
relay contacts are protected internally by sup-
pressor diodes. Relay outputs are protected by
fuses. They act as overcurrent limiters protec-
ting the terminal and relay connections. The
fuses are replaceable. Spare fuses see chapter
8.
