Data transmission on RS485 bus
Inputs
Expander offers 2 inputs (IN1, IN2) of NO and NC type. Input types are defined within low level configuration
(RogerVDM). Input functions are assigned within high level configuration (VISO). Multiple functions can be
assigned to the same input at the same time.
Outputs
Expander offers single transistor output OUT1 and single relay output REL1 with NO/NC contacts and
30V/1.5A max. load. Electric parameters such as polarity are configured within low level configuration
(RogerVDM). Function are assigned to outputs within high level configuration (VISO). Multiple functions with
different priorities can be assigned to the same output at the same time.

NSTALLATION
Each expander is equipped with a holder for installation on DIN35 rail. Therefore expanders can be installed
in ME type enclosures equipped with such rail. Alternatively, expanders can also be mounted using screws
and holes on expander board. It is recommended to install the expander in the same enclosure as PSU.
