The 485OPDRI is our premium Industrial
Isolated RS-422/485 Isolated Repeater. Designed
for rugged industrial environments, it is UL listed
and certified for use in Class 1 Division 2 locations.
Powerful Optical Isolation on both data ports
protects your equipment and data from damaging
ground loops and surges. Additional isolation on the
power supply circuits adds a third degree of
protection.
Packaged in a rugged ABS plastic case, this
repeater operates in wide temperature extremes.
With a 35mm DIN rail mounting bracket, the
485OPDRI is easy to integrate into your control
panel or other industrial equipment.
Installation and configuration is easy with DIP
switches to set up baud rate and serial
communications mode. Removable terminal blocks
make wiring a snap. Power is connected through
separate terminal block that accepts 10 to 48 VDC
from any external source.
Remember, when it comes to reliable
communications in harsh duty industrial locations,
B&
B Electronics ILinx™ Brand is you number one
choice.
