B&R is extending its X20 I/O system to include two additional modules – a temperature measurement module with four wire resistance measurement and an energy measurement module with four current inputs for connecting external transformers with a 333mV output.
Up to four platinum PT100 temperature sensors that are complaint with IEC 60751 can be connected to the X20ATB312 temperature measurement module using four wire connection technology. Wiring the compact four channel X20 module 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 four 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 equipped with three voltage inputs for a maximum of 3 x 480V AC and four current inputs for connecting external current transformers with s 333mV 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.
