4.7.2 DXC-EXT-2RO output expansion
Figure 68: DXC-EXT-2RO
Expansion module DXC-EXT-2RO can be used to convert digital output DO1
(control signal terminals 8 and 9) on DC1-S… variable frequency drives to a
dry relay output K2 (N/O). When this option is used, the variable frequency
drive will have two dry relay outputs available and will be able to switch
voltages of up to 250 V AC and 220 V DC.
