"One Phone Line Connects All Substation Devices"
The RFL 9660 Digital Switch provides a convenient way to connect intelligent relays, smart meters, sequence-
of-event recorders, digital fault recorders (DFRs), or similar devices to a central intelligent digital switch.Through
the use of third-party software packages, the RFL 9660 is able to communicate with Intelligent Electrical
Devices
(IED's). Once connected, the user can access and interrogate up to 32 individually
programmable RS-232 ports. This allows maintenance personnel to instantly access substations from their
desks, without having to make a field trip.
Only a single phone line is required to connect to the RFL 9660; this reduces the number of phone lines
required for polling substation equipment.
By replacing the internal modem with a direct digital interface, the
RFL 9660 can also be connected to an existing substation digital network.
