RFCOM 1Phase CPX3 PLC Modem Board

RFCOM Single-Phase CPX3 PLC module is a high-performance Narrow Band Power Line Communication (NB-PLC) modem Board. It uses Renesas Third Generation Flexible PLC Modem IC “R9A06G037” solution. As default, RFCOM Single-Phase PLC Module is turned with band FCC-150KHz-450KHz. By fine-tuning the components on-board, it can also applicable to Cenelec band Cenelec-A-63kHz.
RFCOM Single-Phase CPX3 PLC module offers great advantage over other PLC solutions, i.e. 1) Low power consumption and low noise interference; 2) High memory headroom for future standard evolution and dual route communication; 3) Including certified software stacks with no additional license fees.
By using RFCOM CPX3 PLC module together with RFCOM T&H Sensor Board and RFCOM 3-phase PLC Basebaord, it is able to build a system at low cost and early stage. The communication data can be propagated through AC or DC power line. It is effective for wiring saving in building automation [HVAC, (air conditioning), Fire & Safety, building security, lighting] etc.
