1.1 Overview

Features of DeviceNet modules

 Electrically isolated bus interface

 Transfer rate up to 500 kBaud

 Easy connection of the frequency inverter, optionally via M12 round plugs or screw terminals

 Looping of the DeviceNet via the modules is possible

 Integrated bus termination resistor

 DeviceNet-specific status display with 2 LEDs

 Module or FI-specific status display with 2 LEDs

 Up to four 24V inputs and two 24V outputs are integrated into the bus module

 Direct connection of up to 4 sensors and 2 activators via M12 round plug connectors on the SK TU4-

DEV-M12(-C) version. Visualisation of signal status via LEDs

 DeviceNet gateway solution → up to 4 frequency inverters can be connected to a DeviceNet module

 Up to 64 DeviceNet modules can be connected to the bus, so that it is possible to operate up to 256

frequency inverters on a single bus.

 Interface (RS232/RS485) for parameter access by means of the SK CSX-3H or SK PAR-3H manual

control unit or NordCon software via RJ12 connector (Except for SK CU4-DEV. Here parameter

access via the SK 200E frequency inverter is possible)

 Available as versions for installation in the inverter (IP20) or in a separate housing (optionally IP55 / IP66)

1.2 Delivery

Check the equipment immediately after delivery/unpacking for transport damage such as deformation or

loose parts.

If there is any damage, contact the carrier immediately and implement a thorough assessment.

Important! This also applies even if the packaging is undamaged.
