Industrial RS-422/485 converters/repeaters with optional 2 kV isolation

  • Boost serial signal to extend transmission distance
  • Wall- or DIN-rail mounting
  • Terminal block for easy wiring
  • Power input from terminal block
  • DIP switch setting for built-in terminator (120 ohm)
  • Boost RS-422 or RS-485 signal, or convert RS-422 to RS-485
  • 2 kV isolation protection (TCC-120I)


The TCC-100/100I series RS-232 to RS-422/485 converters increase networking capability by extending the RS-232 transmission distance. Both converters have a superior industrial-grade design that includes DIN-rail mounting, terminal block wiring, external terminal block for power, and optical isolation (TCC-100I and TCC-100I-T only). The TCC-100/100I series converters are ideal solutions for converting RS-232 signals to RS-422/485 in critical industrial environments.
