Our lightning protection unit rdcLPU is especially designed for use with Robust DC’s isolated products.  One rdcLPU fully protects 2-wire RS-485 or 3-wire RS-232 circuits.

The lightning protection unit has built-in self-resetting current limiters both eliminate the need for external fuses and protects from common continuous over-voltage faults.


  • Works with both RS-232 and RS-485 signals
  • Diverts large surges to ground as per IEC801.5 (6kV/3kA in 8/20µs)
  • Self-resetting up to maximum current of 250 mA
  • 3-wire operation
  • Eliminates the need for third ground wire when used with other RDC products
