The 485OPDR is an optically isolated RS-422/485 isolated line repeater that
can be used to isolate a piece of equipment from the rest of the network. As
a repeater, it extends the distance of an existing network an additional 1.2
km (4000 ft.) and expands it beyond the typical 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.
