2.1.1.2 Description
The connected load is switched via the digital output (relay contacts) from the
control system.
The module has two output channels. Two actuators with ground (earth) wire
may be directly connected to signal output DO 1, N and PE (earth potential) or
signal output DO 2, N and PE.
Each module is equipped with one non-floating make contact relay per chan-
nel, i.e. the fieldside voltage supply (230 V AC or 30 V DC) is connected to
each terminal of the relay and is fed in via the internal power jumper contacts
of an adjacent supply module.
By closing a relay, the field power applied is switched to the second relay con-
nection of signal output DO1 or DO2.
The internal system voltage is used to trigger the relays.
The switching status of the two relays is indicated via green status LEDs.
