Relay outputs
The electronic module has 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”. In order to switch larger capacitive loads, we
recommend installing an additional switching element such as a contac
-
tor or load relay to guarantee longer service life for the contacts. For
details of contact load capacity, see Chapter 3.9 “Technical data” - Relay
outputs. To suppress radio interference, the relay contacts are protected
internally by suppressor diodes. The relay contacts of the alarm or con
-
troller outputs are protected by fuses. They act as overcurrent limiters
protecting the terminal and relay connections. The fuses are pluggable
and replaceable (replacement fuses Type TR5 3,15AT, see Chapter 8.
“Spare parts, Accessories and retrofit kits”).

er devices, the total current consumption must not exceed 6 A.
