2.1.1.2 Description
A connected actuator or load is switched via the relay output module.
The 24 V supply is derived from the power jumper contacts to trigger the re-
lays.
The module has one output channel and enables the connection of one or two
actuators.
The signal output DO has two parallel connections so that an actuator can be
wired using one or two conductors of cross section > 2.5 mm². It is also possi-
ble to connect two actuators in parallel.
The module is equipped with an isolated contact relay so that only the connec-
tion points of the relay contacts are available on the fieldside.
Due to the isolated contacts, it is possible, for example, to connect several re-
lays in series by grouping these modules.
