Description
The connected load is switched via the digital output (relay contacts) from the
control system.
The internal system voltage is used to trigger the relays.
The module has two output channels. Two actuators may be directly con-
nected to signal output DO1 or /DO 1 and N, or to signal output DO 2 or /DO
2 and N.
The module has two isolated SPDT contacts, i.e. only the connection points of
the relay contacts are on the fieldside so that both sets of contacts can be con-
nected to different voltages independent from each other.
Due to the isolated contacts, it is also possible, for example, to connect both
relays in series or several relays can be connected in series by grouping these
modules.
The relay contacts L1 and L2 are supplied with 230V AC or 300V DC exter-
nal voltage.
