Figure 113: DXC-EXT-2RO1AO
The DXC-EXT-2RO1AO expansion module was developed for HVAC applica-
tions. It transforms the DC1 variable frequency drive's AO analog output into
a K2 relay output. This provides the variable frequency drive with two poten-
tial-free relay contacts and enables it to switch mains voltages of up to
250 VAC and 220 VDC.. In addition, analog output AO will be retained and
will output a voltage (0 - 10 V) that is proportional to the output frequency.

For detailed instructions on how to install the module, please
refer to instructional leaflet IL04012014Z.
NOTICE
Internal relay K1 is looped with the expansion module, meaning
it can conduct a lower current ( 1A).
