SPECIFICATIONS

serial ProtoCols

Model 485OP is an optically isolated RS-422/485 signal repeater. In
addition to 2KV isolation on the data lines, it can be used to extend RS­422/485 circuits an additional 1.2 km (4,000 ft.), thereby doubling the
range. An added benefit is the ability to add another 32 nodes to an RS-485
network and join 2 and 4 wire systems.

The compact design fits almost anywhere. Terminal blocks allow easy
installation. Wiring schematic on the label eliminates guesswork. A 12 VDC
power supply is required.
