It exactly meets the technical and economic requirements of the machine building industry. As with all other REX12 devices, no further accessories are required.

The new REX12D-TE2 is ideally suited to the DC 24 V power supply and can be operated with intelligent supply module via communication protocols such as IO link or Modbus RTU. The COM mode allows transmission of measuring and analysis data, control and parameterisation of current ratings. In addition, the REX12D-TE2 can also be operated with supply modules EM12-T. The standard mode allows quick manual parameterisation.

Another product feature of the REX12D-TE2: It forms the basis of the innovative REX-Quat-Pack.

At a width of only 37.5 mm, The REX-Quat-Pack offers four channels with overcurrent protection, each with adjustable ratings from 1 A to 10 A. Current ratings can conveniently be parameterised and read by means of the push button on the device. The user can very easily adjust the combination package to the load conditions of the corresponding DC 24 V application. Besides space savings in the control cabinet, the REX-Quat-Pack also offers reduced stockkeeping because the four-channel-solution only carries a single part number.
