TCC-120/120I Series

Features and Benefits

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

Overview

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 an 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.
