Industrial Isolation RS232/485/422 Converter and Repeater

IT-SC485GI-SW Can use for RS485/422 repeater and RS232 to RS485/422 converter, but just use one function at same time. The product must have 12-36VDC power input, optic- electrical isolation more than 3KV. Have small volume, 3000m transfer distance, high rate, steadily performance and so on. It is abroad used in industry control system, It is a best performance and price interface converter and Repeater.




  • Support DIN-rail, Terminal block connection
  • 12~36VDC Power input (3 bit terminal block)
  • Adopt itself adapt interface technique, no use for setup switch
  • Adopt ADDC, auto distinguish and data transfer direction.
  • Can use for RS485/422 repeater and RS232 to RS485/422 converter, but just use one function at same time
  • Supply 3000V optic-electrical isolation, 1500W surge protection
  • Reach up to 3000m at the rate of 9600bps
