SPD for RS-485/RS-422 data and signal lines.

Maximum Circuit Voltage
6.63V (L-G)
Clamp Voltage
15V maximum at 1.2/50µs-1,000V
Repetitive Surge Guaranteed
8/20µs-1,000A, 100 times


  • Consists of RSSA (silicon surge absorber) and RAV
  • Excellent response time and endurance
  • Small gain loss in long distance communication by use of common mode choke coils in impedance blocks
  • PCB, terminal block and DIN rail mounting options


RS-485/RS-422 data and signal lines. Protects driver/receiver ICs in input-output terminals from surge (such as lightning).
