Optically Isolated
RS-422/485 Repeaters
485OP, 485OPB
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
RS-422/485 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.
• 2 KV isolation
• Add up to 32 nodes to RS-485 network
• RS-422 2-wire, RS-485 2 or 4-wire
• Modbus
• UL Recognized (Model 485OP only)
