B&B Electronics ILinx family of industrial grade converters and repeaters boast top notch, 3-way optical isolation for rugged applications. Data ports are isolated from each other. Power supply is fully isolated with operation from 10V all the way up to 48V. With more installations having 48 VDC rails, you can take full advantage of your power rail and eliminate a power supply. Most are UL Class 1 DIV 2 rated, making them perfect for use in hazardous locations (see product details for specific ratings). They will also operate reliably in temperatures ranging from -40° to 185°F (-40 to 85°C). Whether it is RS-232, RS-422, RS-485, Single-mode Fiber Optic, or Multi-mode Fiber Optic; you can't go wrong when you choose a product from B&B 's ILinx family for your industrial serial data communications needs.

ILinx Converters

485DRCi: RS-232 to RS-422/485 Converter
Model 485DRCi industrial-grade isolated serial converter changes RS-232 signals to RS-422 for increased range, or RS-485 for increased range plus multi-drop capability. cUL Class 1 DIV 2 approved. 
 

FOSTCDRi: RS-232/422/485 to Multi-mode Fiber Optic Converter
Model FOSTCDRi industrial-grade isolated converter changes RS-232, RS-422, or RS-485 to Multi-mode Fiber Optics, extending range up to 2.5 miles (4 km). UL Class 1 DIV 2 approved.
  

FOSTCDRi-SC: RS-232/422/485 to Single-mode Fiber Optic Converter
Model FOSTCDRi-SC industrial-grade isolated converter changes RS-232, RS-422, or RS-485 to Single-Mode Fiber Optics, extending range up to 9 miles (15 km). cUL Class 1 DIV 2 approval is pending.
  

ILinx Isolated Repeaters

232OPDRi: RS-232 Isolated Repeater
Model 232OPDRi isolates four RS-232 lines, two data lines in each direction, or one data line and one handshake line in each direction. Use as a repeater to extend the RS-232 signal beyond 50 feet (15 meters). cUL Class 1 DIV 2 approved.

485OPDRi: RS-422/485 Isolated Repeater
Model 485OPDRi isolates one piece of RS-422/485 equipment from the rest of the system, or one RS-422/485 local group from another.

Model 485OPDRi repeater adds 4,000 feet (1.2 km) and another 32 nodes to an RS-485 data circuit. By configuring one side as RS-422 and the other as RS-485, Model 485OPDRi can acts as a converter to allow your four wire RS-422 equipment to talk to a 2-wire RS-485 device. UL Class 1 DIV 2 approved.
