Bidirectional opto-isolated RS232 to RS485 converter allows to interface your devices using RS232 communication link to balanced differential RS485/RS422 link and vice-versa. Surge Protected Interfaces Protect Equipment, High Speed Data and the Converter Powered RS485 isolator provides optical isolation up to 2500Vrms 500DC continuity; transient voltage suppressor TVS supports 600W lightning surge protection over each line of RS485/422 link; 15KV static protection over RS232 link effectively protects your value devices against high voltage spikes. With built-in booster to amplify signals, it’s a quick simple solution for most industrial automation, commercial computer network application, motor control, even tough environments to have PC in charge of controlling a given process in long haul data acquisition and control applications. Automatic Data Direction Control ADDC - detect the incoming or outgoing data and automatically switch into the send or receive mode, so no need to worry about data collision problems. Rack-mounted serial adapter box offers multiple interfaces : RS-232 end is a standard DB9 female connector, RS-485/RS-422 end offers 2 interfaces to chose from: RJ45, screw terminals. Specific RS232 Link : DB9 Female RS-485/RS-422 Link : RJ45 Female, 6 Position Terminal Board Standards: EIA RS-232, RS-485, RS-422 Signals: RS-232 (TXD, RXD, GND), RS-485 (T/R+, T/R-, GND), RS-422 (T/R+, T/R-, RXD+, RXD-, GND) Port Protection: 1500 W surge, 15 kV static discharge; Isolation: 2500Vrms isolation voltage, 500DC continuity DC/DC Max Distance (RS-422/RS-485 link): 1.2km at 9600 bps, 600m at 38400 bps, 300m at 115200bps Loading: 32 nodes; wired via twisted pair or shielded wire What's Included 1 x Mountable RS-232 to RS-485 Adaptor 1 x Power Supply Adapter 1 x Terminal Board 1 x DB-9 Male to Female Cable 1 x Manual See moreBi-directional RS485 to RS232 isolator box supports 4 kinds of data communication: point-to-point/point-to-multilpoint 4-wire full duplex; point-to-point/point-to-multilpoint 2-wire half duplex. Rack-mounted optocoupler with built-in repeater to amplify signals; with automatic baud rate sensing (300bps to 115200 bps); well housed in metal case ensures rapid heat dissipation. Port-powered or by DC 9V-24V power adapter; LED indicators for troubleshooting - easy check in the status of power connection and balanced differential signal status. Serial converter provides Power Supply Isolation (optical isolation voltage 2500Vrms 500DC continuity); RS-232 interface - 15kV ESD protection; RS485/422 end with each line of 600W lightning surge protection to protect your electric devices. Industrial grade isolated RS232 to RS485 converter for High Speed data communication between DB9 serial COM port and RS-485/422 device (wired via RJ45 socket or 6 position terminal board).
