Advantech BB-232OPDR

RS-232 Isolated Repeater

  • Extend RS-232 Data another 50 ft (15.2 m)
  • 2000V Optically Isolated Data Lines
  • -40 to 80°C Operating Temperature
  • Complies with NEMA TS1 & TS2 Environmental requirements for Traffic Control Equipment


The 232OPDR is a DIN Rail mountable RS-232 optical isolator and repeater. It provides 2000 V Isolation for four RS-232 signal lines, two in each direction. The isolator has four LED’s to show data flow and one LED to indicate power. Connections are made to a terminal block. The isolation provides protection for computer equipment from ground loops and induced currents caused by lightning or heavy electrical loads. It also functions as a repeater to extend RS-232 signals another 50 feet. The 232OPDR can support two data pairs or one data pair plus control signals in both directions.
