Acromag’s RS-485 network repeater device allows users to take full advantage of the RS-485 standard’s extended communication distances and multi-dropping capabilities. In addition, these devices offer field selectable End-of-Line Network (EOLN) terminations on both the A and B networks.

Operation is transparent to all devices and no handshaking is required. Up to thirty-two RS-485 devices can be driven. Network repeaters are ready to mount on any base plate. Or, for a harsh environment, it can be installed in a NEMA enclosure of your choice. No enclosure is necessary for use in a laboratory or office. Installation requires mounting, connecting power and cables, and setting the baud rate.

  • Designed for use with Johnson Controls N2 or BACnet bus.
  • I/O signal isolation. No handshaking. No extra control lines.
  • Baud rates of 600, 1200, 2400, 4800, 9600, 19.2K, 38.4K, and 76.8K are switch selectable.
  • Field-selectable end-of-line network terminations on both A and B sides.
  • Electrical transient protection is provided. This protects the host computer from destructive noise spikes and other transient signals.
  • Status LED’s indicate transmission direction, RS-485 bus fault conditions, and power applied.
  • 115V, 230V, and 24V AC power models available
