The 485OPDR is an optically isolated
RS-422/485 isolated line repeater which can
be used to isolate a piece of equipment from
the rest of the network. As a repeater, it
extends the distance of an existion network
an additional 4000 ft (1.2 km) and expands it
beyond the 32-node limitation. Data signals
and the power inputs connect to the terminal
block. 600W surge suppression ensures
that the connected equipment is protected
even in the harshest of environments. 2-
Wire RS-485, 4-Wire RS-485 and RS-422
are supported.
The repeater operates on externally
sourced 10 to 30 VDC power. The
enclosure has a DIN rail mount that is
designed to fit easily on a standard 35mm
rail. The 485OPDR is ideal for your
critical industrial communications needs.
