Introduction
Model BB-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 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, 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 (power supply required, not included, sold separately).
