All timer values are factory set for optimum performance
for each application. All settings are recorded on
customer specific applications drawings.
• Each RFL 9780 station is pre-wired so that all input
and output connections for the standard features are
made to the same terminals on each station.
• All RFL 9780 stations are equipped with carrier level
indicators, a transmitter output power alarm, and a
low receiver input alarm as standard equipment.
Skewed or transformer hybrid modules are also avail-
able for use with the RFL 9780 and fit within the same
chassis.
Options for the RFL 9780 include permissive coordinat-
ing, and more. RFL’s sales and engineering staff can cus-
tom configure the 9780 for virtually any input, output, or
logic requirement, making it the most flexible single func-
tion powerline carrier system available to date.
The optional Sequence of Events (SOE) Module provides
a record of 40 events. Table 2 below, shows the data
points monitored for a standard TX/RX Terminal.

• 48V/125V and 250V internal power supply options.
Systems may be equipped with redundant supplies
in a single chassis.
Custom application requirements, such as functional
test panels, additional trip & guard contacts, redundant
channels, and 50 and 100 Watt RF power amplifiers can
be accommodated. Options may require an additional
accessory chassis.
• RF interface withstands a 3KV 1.2/50 µs pulse as
specified in C93.5-1997
