September 6, 2006 - Tame rogue data line signals that can garble a message or damage electronic components by inserting an optical isolator in the data line. Rogue currents can have many causes, from exposure to a minor power surge in a nearby electrical circuit to a lightning strike in the vicinity.Optical Isolation works by converting a voltage signal to an optical signal which passes through an fiber optic section before being converted back to a voltage signal. This process isolates any voltage anomalies from the protected equipment. Mike Fahrion, Director of Engineering for B&B Electronics in Ottawa, Illinois said, "Optical isolation can now be considered a requirement for commercial and industrial data communication.
Spikes and surges on the data line can create havoc in industrial applications. If you get a surge in the home or office, you may have to reboot, which is an inconvenience. But the same surge in a computer controlled industrial application can shut down an assembly line or an entire plant. That's a disaster.
Adding optical isolation, either with a stand-alone isolator or a converter with optical isolation, can stop those damaging spikes and surges in their tracks." B&B Electronics has introduced the expanded I-linx series of premium industrial data converters and other data products that include superior optical isolation. New I-linx serial converters with superior isolation change RS-232 format data signals to RS-422 for increased range, or RS-485 for increased range and multi-drop capability.I-linx stand-alone optical isolators in industrial DIN rail mount cases and 2000 V protection are now available for RS-232 and RS-422/485 data circuits.Fiber optic data transmission provides intrinsic optical isolation.
B&B offers their Model FOSTCDRI that converts RS-232, RS-422, or RS-485 to transmit over fiber optic cable. Fiber optic cable also allows range to be increased up to 2.5 miles (4 km). A multi-drop arrangement can easily be set up, allowing one serial device to talk to multiple slave devices around a fiber ring.All I-linx devices are in DIN rail mount cases and made rugged for industrial applications.
The new I-linx line of optically isolated converters and isolators is now available from B&B Electronics.
