The TCC-100 and TCC-100I are RS-232 to RS-422/485 converters that 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 only). The TCC-100/100I are ideal solutions for converting RS-232 signals to RS-422/485 in critical industrial environments.
