RD-48
RS-422/485 Repeater
RD-48 is used to extend an existing RS-422/485 bus or as a converter between 
2-wire and 4-wire applications. According to the standard the RS-422/485 bus 
can support a total of 32 connected devices and a transmission range of up to 
1200 metres (4000 ft). Up to 8 repeaters can be used in series to extend the range
or the number of connected devices. Each repeater allows a further 1200 metres
(4000 ft) range and an additional 31 connected devices. RD-48 supports data rates
up to 1.5 Mbit/s. The RD-48 provides total galvanic isolation, so it can also be used
as an isolator to protect equipment e.g. a PLC. RD-48 is intended for mounting on a
35 mm DIN-rail, where the modem is attached and locked in a single action.
