Introduction
Isolated Industrial RS-422/485 Converter/Repeaters
Ordering Information
The TCC-120 is an RS-422/485 converter/repeater designed who to 
extend RS-422/485 transmission distance.It has a superior industrial-
grade design, with DIN-rail mounting, terminal block wiring, external 
terminal block for power, and optical isolation for system protection 
(TCC-120I). For critical industrial environments, the TCC-120 is an 
ideal converter or repeater of RS-422 and RS-485 signals.
