RFL 9785 Programmable ON/OFF Powerline Carrier System
The RFL 9785 is an amplitude-modulated ON/OFF Powerline carrier transmitter/receiver terminal. It is based on three generations of proven RFL technology, with enhanced features to meet today's market demands. These features include improved RFI and surge withstand capabilities (meeting the requirements of ANSI/IEEE C93.5), ESD protection (per IEEE PC 37.90.3, 2001), available redundant power supplies, increased flexibility through field programmable frequencies and logic, reflected power measurement option, and no cost WindowsTM web based user interface.
The RFL 9785 is designed for directional comparison blocking applications in high-speed protective relaying communications. Its interface circuits are compatible with almost every existing carrier blocking relay. One standard package is all you will need for most schemes. A complete 10 watt transmitter/receiver is contained in a 19-inch chassis that occupies three rack units of vertical rack space (5.25 inches, or 13.3 cm). An optional voice service channel, checkback module, sequence of events and redundant power supply can also be added in the same 3U chassis.
