Given the need to reduce costs in switch cabinet construction, interface units offer an alternative to wiring concepts with point-to-point wiring.

The prime function of interface units is to act as a trouble-free adapter element between standardised plug connectors and point-to-point wiring or other connection systems.

Advantages of the interface units:

• Two- and three-storey PCB terminals save space
• Conventional point-to-point wiring only needed on one side to save costs
• Greater safety, preventing wiring errors
• Optional: LED status display on the interface units
• Rapid troubleshooting with additional test and measuring devices
• Simplified initial commissioning and documentation.
  

Preassembled leads with the corresponding plug connector systems are used as the connection between the series-connected controller and the interface unit.

This provides the greatest savings for the user. The use of interface units reduces the individual circuitry, which reduces labour and installation time and also hidden costs in particular a reduction material costs following a reduction in the number of individual cables and leads, cable ducts, terminals and terminal blocks required. The transition to point-to-point wiring takes place at directly at the interface element.

 

Interface units let users implement pioneering concepts in switchboard design with potential for rationalisation. Customised wiring concepts can also be solved rationally through the use of special interface units.
