7.1.2 DXC-EXT-2RO output expansion
Figure 88: DXC-EXT-2RO
Expansion module DXC-EXT-2RO can be used to convert digital output DO1
(control signal terminals 8 and 9) on DC1 variable frequency drives to a dry
contact relay output K2 (N/O). When this option is used, the variable
frequency drive will have two dry relay contacts available and will be able to
switch voltages of up to 250 V AC and 220 V DC.

For detailed instructions on how to install the module, please
refer to instruction leaflet IL04012015Z.
NOTICE
Internal relay K1 is looped with the expansion module, meaning
it can only conduct a lower current ( 1A).
DANGER
Dangerous voltage!
Expansion module DXC-EXT-2RO1AO must not be placed
into operation until all mounting and installation work has been
completed. Any other use will be considered to be an
inappropriate use.
