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