Tag rs232


ZCONV485 is an efficient and compact RS232 – RS485 self-powered converter.

It connects directly to the RS232 port using the classic 9-pin SUBD connector. From this it derives also the current necessary for its operation.

On the opposite side there are 6 terminals with a 5.08 mm pitch to which the RS485 communication cable is to be connected. It is also possible to supply the converter directly from the bus by applying a voltage between 9 and 24 Vdc.

Technical characteristics, RS232 side:

  • Data Rate up to 120 kpbs
  • ESD +/-15 kV (HBM – Human Body Model)
  • Meets or Exceeds the Requirements of TIA/EIA-232-F and ITU v.28 Standards
  • Max supply current 15 mA

Technical characteristics, RS485 side:

  • Maximum bumber of end node: 32
  • Low Supply Current, 5 mA Max
  • Meets or Exceeds the Standard Requirements of ANSI RS-485 and ISO 8482:1987(E)
  • Common-Mode Voltage Range of −7 V to 12 V
  • Positive- and Negative-Output Current Limiting
  • Driver Thermal Shutdown Protection
