Material number:
  • X2X SmartWire master for controlling up to 16 SmartWire slaves
  • Simple connection using pre-assembled connection cables
  • Moeller SmartWire modules for Moeller standard switching devices
  • Replaces control circuit wiring
  • Contactor activation
  • Contactor switching status
  • Motor circuit breaker status
  • 24 VDC control voltage via SmartWire connection cable

SmartWire from the company Moeller makes it possible to very easily integrate switching devices such as contactors or motor protection switches in the X20 system without extensive wiring. It replaces the control circuit wiring between the controller and switching devices with pluggable, pre-assembled connection cables.

Although SmartWire is an intelligent connection, this changes almost nothing for the machine programmer. Integration in the X20 system via the interface module cuts down on overall communication. The individual switching devices can simply be viewed as digital inputs and outputs.

Practical applications

SmartWire allows up to 16 switching devices to be connected using pre-assembled cables and attached to the X20 SmartWire interface module. The system can configure itself completely at the push of a button without additional intervention or effort. This replaces the wiring test that was previously necessary.

At the same time, the device configuration is known to the system. If a device is no longer available due to an error or intervention, it will be detected immediately. Once corrected, the system continues to run.

The interface module is designed as a normal electronic module, which means it can be placed anywhere on the remote backplane.
