Isolated 3-Way RS-485 Arbitrator [rdc485Arb]
$ 1,399.00 exc. GST
- Isolates, repeats and arbitrates on RS-485 signals
- Allows 2 masters to communicate with one slave via buffering of master ports
- 3-port switching for communication between ports A & C or B & C
- 2-wire operation (T+, T-, GND) for each port
- Requires standard 8,N,1 byte format
- Voltage Input : 9 to 36 Vdc – Accepts unregulated 9 to 36v DC power supply. Suitable for industrial 24vdc supplies, 12v or 24v battery systems, or supply from any low-cost DC transformer pack. Fully in-rush and surge protected.
- 4-port Isolation – 4 of 4 ground isolation means all data grounds are 100% isolated from each other and the power supply ground. Like 3 of 3 ground design, this is always the safest design option. All redundancy – supporting products (hubs, arbitrators etc) are based on this design.
- Removable 3-way screw terminals at all ports – We uses only quality parts from vendors with published specs. We know that all of our screw terminals have consistent force and spring ratings. They will hold your wires indefinitely without vibrating loose.

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.
