Isolated RS-232 Hub (3-way) | rdc232hub
$ 520.00 exc. GST
Our rs-232 Hub is an incredibly handy device for use in distributed industrial applications. It provides an electrically safe, fool-proof, hands-off method to share an RS-232 programming port with both a remote engineering work-station (EWS) and a local work-station or note-book computer (LPC). It is robustly designed for excellent engineering!
Warranty: 36 months

Isolated RS-232 3-way hub – Master to 2 slave devices
Product Code: rdc232Hub; rdc232hub-dv-4p-dd-F1
Our rs-232 hub allows the interconnection of three RS-232 devices, complete with full 4-port 2.5kv optical/galvanic isolation. Each port is fully isolated (with floating ground) with reference to the other data ports and the power supply. 500-watt voltage transient suppressor diodes protect the hub from normal mode surges, while the full galvanic isolation protects the hub from common mode surges.
The hub operates either in Hub or Master-Slave mode. As a hub, any one device can communicate freely with the other two because data received on any one port is echoed out through the other two.
- In 3-way hub mode (internal jumper J3 removed): half-duplex data flows freely between all three ports A, B, & C. It allows the 232hub to act like a 3-node RS-485 network without the need for RS485.
- In Master-Slave mode (internal jumper J3 installed): full-duplex data flows freely between either ports A & C, or ports B & C. It allows one master device to talk to 2 slaves, or two devices (a primary & backup) to share one resource.
Key features:
- Isolates and repeats RS-232 signals
- Various isolation options available
- Protocol Independent
- 3-port Master/Slave or Hub operation
- 3-wire operation (TX, RX, GND) for each port

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.
