The CU320-2 Control Unit features the following interfaces as standard:

• 4 DRIVE-CLiQ sockets for communication with other DRIVE-CLiQ nodes, e.g., Motor Modules, Active Line Modules, Sensor Modules, Terminal Modules¹⁾
• CU320-2 PN:
  1 PROFINET interface with 2 ports (RJ45 sockets) with PROFIdrive V4 profile
• CU320-2 DP:
  1 PROFIBUS interface with PROFIdrive V4 profile
• 12 parameterizable digital inputs (isolated)
• 8 parameterizable bidirectional digital inputs/digital outputs (non-isolated)
• 1 serial RS232 interface
• 1 interface for the BOP20 Basic Operator Panel²⁾
• 1 slot for the CompactFlash card on which firmware and parameters are stored
• 1 slot for mounting an option module (e.g. TB30 Terminal Board)
• 2 rotary coding switches for manually setting the PROFIBUS address
• 1 Ethernet interface for commissioning and diagnostics
• 3 test sockets and one reference ground for commissioning support
• 1 connection for the electronic power supply via the 24 V DC power supply connector
• 1 PE/protective conductor connection
• 1 ground connection

A shield connection for the signal cable shield on the option module is located on the CU320-2 Control Unit.

The available option slot is used to expand the interfaces, for example, to include additional terminals or for communication purposes.

The status of the CU320-2 Control Unit is indicated via multi-color LEDs.

As the firmware and parameter settings are stored on a plug-in CompactFlash card, the Control Unit can be changed without the need for software tools.

The CU320-2 Control Unit can be mounted on the side of the Line Module in booksize format via brackets integrated in a Line Module. The CU320-2 Control Unit can also be fixed to the wall of the control cabinet using the integrated fixing lugs. As the CU320-2 Control Unit is not as deep as a Line Module, suitable spacers are available to increase the depth of the CU320-2 Control Unit to 270 mm (10.63 in).
