4.7.1 DXC-EXT-IO… coupling module
Coupling modules DXC-EXT-IO110 and DXC-EXT-IO230 can be used to
integrate the digital inputs on DC1-S… variable frequency drives directly into
control circuits with 110 V AC / 230 V AC. In the actual coupling module, the
inputs (connection terminals 1 to 4 and 12 and 13) are galvanically isolated
from the DC1-S… variable frequency drive’s digital inputs (DI1 to DI4).

expansions, please refer to Application Note AP040032
