Isolated serial repeater extends and isolates RS-422/485 serial networks

9th April 2013


B&B Electronics Manufacturing Co Inc, a developer of rugged wireless and wired M2M connectivity solutions for harsh environments, has expanded its family of serial isolators and repeaters with the 485OPDR-HS high speed, isolated repeater.  

Developed for use in high speed fieldbus systems like Profibus, as well as Modbus and other asynchronous serial applications, the 485OPDR-HS extends and protects RS-422 or RS-485 serial networks at speeds of up to 1.5 Mbps and ranges of up to 4000 feet (1.2 km), depending upon the data rate. Its compact (1.0 x 3.1 x 3.7 in/ 2.5 x 7.9 x 9.5 cm) form factor and top and bottom loading terminal blocks make the 485OPDR-HS easy to install and easy to fit into cramped industrial automation control panels.

The 485OPDR-HS is designed, built and tested to meet heavy industrial (EN61000-6-2) standards.  It features a wide (-40 to 80°C) operating temperature range, it can use 10 to 30VDC input, and it is DIN-rail mountable on a standard 35mm rail.  Setup is easy; the 485OPDR-HS automatically senses the data rate and users can configure RS-422/485, 2-Wire or 4-Wire, using DIP switches.

The 485OPDR-HS provides 2 kV isolation, 8 kV air ESD protection and 600W transient voltage suppression on the data lines. Its 'Triple Isolation' protects the data input, data output and power connections. The 485OPDR-HS is targeted at industrial automation applications where drives, PLCs, temperature controllers and other devices are installed in harsh electrical environments that present a high risk for ground loops.
