Industrial RS-422/485 Isolated Repeater
485OPDRI
The 485OPDRI isolated RS-422/485 repeater is 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 add 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, it easily
integrates into control panels 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.
