Black Box RS-232 to RS-422/RS-485 DIN Rail Converter

Black Box RS-232 to RS-422/RS-485 DIN Rail Converter

Convert async RS232 to RS422/485 at speeds up to 19.2 kbps with distances up to 4000 ft over CATx cables. These devices are great for connecting RS232 devices into an existing RS422/485 environment in factory automation, building automation, and process automation. They can be mounted using DIN Rail and can withstand operating temperatures of -40 to 176 degrees F (-40 to 80 C).

• Switch-selectable data rates between 2400 bps and 19.2 kbps.


• Optically isolates and converts unbalanced half- or full-duplex RS-232 signals to optically isolated and balanced full-duplex RS-422 or 2-wire half- or 4-wire full-duplex RS-485.


• Async (data leads) only.


• Powered by 10-30 VDC, 100 mA


• 2-wire half-duplex or 4-wire full-duplex, RS-422 Full-duplex


• Transmit data up to 19.2 kbps or at distances up to 4000 ft.


• Withstands operating temperatures of -40 to 176 degrees F (-40 to 80 C).
