TCC-120/120I Series

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

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)

Certifications

Introduction

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.
