The STEVAL-XPLM01CPL is a simple yet very useful tool for power line communication testing on AC power networks.


It includes simple two-wire connectivity to any PLC transmitter/receiver and a standard connector for an AC power cord (2-pin AC plug, 8-shape female end). The main components to achieve suitable signal coupling are:


- PLC 1:1 transformer for differential coupling and basic electrical isolation


- SM6T15CA 600 W Transil +320 V ac varistor for effective protection against ESD, EFT and surge disturbances from the power line


- High voltage AC blocking capacitor with X2 safety class


- Tuning series inductor to adjust the frequency response


The STEVAL-XPLM01CPL can be very easily interfaced with the X-NUCLEO-PLM01A1 to test PLC communication performance over an AC mains network.


The frequency response of the coupling circuit is wide enough to fit any narrow-band PLC signal under normal test conditions. However, it can be easily adjusted by changing only the tuning series inductor L1.


The STEVAL-XPLM01CPL is suitable for lab measurements using equipment like an isolated probe for an oscilloscope or a spectrum analyzer, or to inject a signal from an arbitrary function generator.

Key features
  • Complete AC coupling circuit suitable for use with any power line communication (PLC) solution
  • Can be paired with the X-NUCLEO-PLM01A1 to add full AC coupling capability
  • Tuned for transmission inside CENELEC B to D bands
  • Implements isolation and protections for safe operation
  • Suitable for the connection of laboratory equipment for PLC measurement and testing
  • RoHS compliant
