This converter must be powered by an external 9 to 30VDC power supply (not included).Ī 4-feet M/F Serial cable is included in the package. This design makes a very reliable and high performance converter. Optical isolation is achieved with high speed 6N137 isolation opto-couplers from Fairchild Semiconductors. The UT-503 is designed with the industry proven and very reliable SP202E line driver from Exar. The CON-485/422-REP is a rugged industrial-grade high quality external powered bi-directional 3KV RS485 / RS422 isolator with 15KV ESD and 600W surge protection. When choosing a converter for industrial or other critical communication finding a reliable product is essential.
No jumpers, drivers or other software needed. The converter automatically senses whether RS422 or RS485 is connected to the interface, simply connect the wires and its ready to use. LED indication lights for TX, RX and power makes it easy to see when power is on and when communication is present. In the author’s case, the system operates at. This design is for a simple half-duplex optically isolated interface that converts a 20 mA current loop (connected to J2) into an RS232 signal (on J1) which can be monitored by, say, a laptop PC. The housing is made of hardened ABS plastic, so it won't break easily, and can be installed on a standard DIN rail or mounted with screws. Opto-Isolated RS232 Interface Schematic Circuit Diagram. This will also protect against data loss and other communication errors. The isolated interface will effectively protect your devices and the converter itself against most types of high-voltage surges, spikes and ground-loops for up to 2500Vrms/600W and 15KV EDS static protection for each data line. The Black BOX RS-422 and RS-485 Optical Isolator/Repeater enables you to connect equipment meant for a point-to-point RS-422 4-wire interface to an RS-485 2. SC Standard Single Mode Fiber Media Converter RS232/RS422/RS485 Serial To Fiber. This is a fully optically isolated RS232 to RS485 / RS422 converter ideal for all industrial applications and projects sensitive to high voltage spikes. The BLACK BOX RS-422 and RS-485 Optical Isolator/Repeater enables you to connect equipment meant for a point-to-point RS-422 4-wire interface to an RS-485. Features Plug-and-play, hot pluggable Extends RS-232 / RS-422.
