For connection and galvanical insulation of devices with interfaces RS232, RS485, RS422 (RS485F) and current loop.

General specification:ISO485DR 1

  • Own power supply 220 VAC, built-in overload protection.
  • Three-way galvanic insulation.
  • Baud rate - up to 125 Kbps.


Specific technical features:

  • ISO485DR, REP485DR-B, REP485DR-C - automatic send data control.
  • ISORS422-B – control of transmission direction by RTS signal in half duplex mode, without transmission direction control in full duplex mode.
  • REP485DR-B Plug&Play repeater, extends the line / increasing the number of the devices in the RS485 network.
  • REP485DR-C - extends the line / increasing the number of the devices in the RS422 network.
  • ISORS-CL - an active device, feeds the current loop, capable to operate from 4 to 54 mA. Without control of the data transmission direction.
  • ISORS422-B, ISORS-CL – cable are leaded via cable glands.
