TCC-120/120I
Industrial RS-422/485 converters/repeaters with optional 2 KV isolation
The TCC-120 and TCC-120I are RS-422/485 converters/repeaters
designed to extend RS-422/485 transmission distance. Both
products have a superior industrial-grade design that includes
DIN-rail mounting, terminal block wiring, and external terminal block
for power. In addition, the TCC-120I supports optical isolation for
system protection. The TCC-120 and TCC-120I are ideal RS-422/485
converters/repeaters for critical industrial environments.
› 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)
