The rdc485ir safely connects 2/4-wire RS-485 devices
and networks together without danger of ground
loops and damaging surges. It also doubles permitted
cable length. The isolated DC supplies provide full
3-port galvanic isolation up to 2.5 KV, which also
implies that the grounds of the data ports are floating
with respect to each other as well as the supply port.
In 2-wire mode, data direction control is fully
automatic. The internal terminating resistor (120
ohms) and bias resistors can be enabled via jumpers.
500 watt voltage transient suppressor diodes protect
the rdc485ir from normal mode surges, while the full
galvanic isolation protects the rdc485ir from common
mode surges. With the "Fault Isolation" (FI) option,
line breaks and/or shorts on Port A's segment will not
interfere with the data on Port B's segment.

Isolation, industrial design, small size, DIN rail mount,
user indication, and DC supply make the rdc485ir a
very engineer-friendly device for your industrial data
communication system.

When a line fault (short or
open-circuit) occurs at any
one of the segments, the
other segments will not be
affected.
For example, when a line
short occurs between slaves
3 and 4, the Master will still
be able to poll slaves 1 and 2
