INCOTEX has developed and now produces PLC-modems for embedding as daughter board in micro processor energy meters. Basic specification of such devices is extremely low energy consumption and very strong resistance towards noises and signal attenuation on the line. Dimensions of device are 40x60x22 mm (including own network power supply unit). Simplified modem circuit diagram is given below.


  • Supply voltage, V – 220/230
  • Working frequency range, kHz – 20-95 kHz
  • Transmitter signal amplitude – 1В … 1,5V
  • Type of receiving modulation – PSK
  • Type of transmitting modulation – OFDM
  • Type of external interface – logic UART 3.3V
  • Dimensions, mm – 40х60х22
