B&R Automation's X20 I/O system series has added a temperature measurement module with 4-wire resistance measurement and an energy measurement module with four current inputs for connecting external transformers with a 333 mV output.

The X20ATB312 temperature measurement module uses 4-wire connection technology and has up to four platinum PT100 temperature sensors that are complaint with IEC 60751. Wiring the compact 4-channel X20 module, which has a width of only 12.5 mm, is done using a X20TB1F 16-pin terminal block. In addition to resistance temperature measurement using PT100 sensors that have a constant current supply for the 4-wire connections and a resolution of 0.01°C, the module also allows direct resistance measurement and offers the possibility to individually set the filter time.

The X20AP3161 is an energy measurement module that is equipped with three voltage inputs for a maximum of 3x 480 V ac and four current inputs for connecting external current transformers with s 333 mV output. The module measures effective, reactive and apparent power individually for each of the three phases and for all of them collectively. The power consumption of each phase and the total sum is also recorded. The module measures current and voltage up to the 31st harmonic, so it is highly precise. The signals are pre-processed before being passed on in the form of digital variables, which reduces the load on the controller.
