Lightning Protection Unit for RS-485/232/422 | rdcLPU
$ 199.00 exc. GST
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

About Robust DataComm
Robust DataComm Pte Ltd is a Singapore-based company specialising in industrial communication products since 1994. The company is backed with decades of industrial experience and coupled with our well-documented processes
Capabilities
RDC devices is design with fully galvanic isolation and capabilities to meet, solve and maintained industrial data communication network in harsh environment.
Our devices have three ports of isolation with both sides of the data communication having floating power supplies. Our data direction control is fully automated
In case of receiving any unnatural activation or surge from the power supply or signal line, it will not further damage to other parts of the system.
In term of function, we focus and specific on only one function without any complicating settings and only minimum settings are require. It is easily install and connect mainly plug and screw.
Our device have a wider range of power supply voltage ranging from 9 ~ 36VDC.
We designed the device to smaller size for compact environment. The weight is very light with case material made of polyamide nylon, fungus and termite resistant and self-extinguishing (UL94 V2) as stated in our datasheets.
