PLC Terminals

Power line carrier (PLC) describes the process of using high-voltage powerlines as the means for communication transmission. A PLC channel includes the signal path from the transmitting equipment at one terminal, through the tuning equipment at the receiving end, and into the receiving terminal. In duplex (bidirectional) operation, a signal is sent over the same path in the opposite direction and on a different frequency.

RFL's FSK/On-Off and Single Sideband PLC terminals provide highly-reliable power system protection. Many of RFL’s products are backed by a 10-year warranty, along with product and field support, and commissioning assistance. RFL PLC platforms provide the highest level of security and dependability, to help deliver power safely, reliably and cost effectively.
