Isolated RS-485 Serial Repeater (4-wire) | rdc485ir
$ 549.00 exc. GST
Our isolated serial repeater (rdc485ir) is specially designed to connect both 2 and 4-wire RS-485 devices and networks together. It isolates and protects the data signals and power supply grounds, and also doubles permitted cable length. Fault Isolation option available. The isolated repeater also comes with LED indicators and power status for rapid troubleshooting.
Warranty: 36 months

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.
