RS232 converter to RS485-RS422 network

RS232 converter to RS485-RS422 network


Product description

It is the RS232 - RS485 / RS422 converter with greater features for coupling and integration in an industrial network, allowing to increase the number of machines to communicate and extend the communication lines with the central unit.

Incorporating a high-frequency filter and greater isolation ensures communication in the worst working conditions.

Features

  • Opto-isolated converter with galvanic isolation between the RS232 and RS422/RS485 channels.
  • Insulation of Class II equipment (double insulation). Insulation between ports is 3.750 V.
  • Maximum of 32 equipments.. Bus 1.300 meters long, according to RS485 standard.
  • Transmission speed of 57.600 bauds through the RS232 and RS485/RS422 ports.
  • The beginning and end of line resistors are built into the unit and are selected by an external jumper.
  • Plug-in terminal for the RS485/RS422 port and SUB-9c connector for the RS232 port.
  • Selection of the RTS working mode and RS485 or RS422 selection through external jumpers.
  • Three status LEDs to indicate transmission, reception and equipment power supply.
