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.
