Serial data communications lines can carry damaging electrical transients caused by anything from ground loops to lightning strikes. So where do you deploy isolation, and where do you use surge suppression? A surge suppressor directs high voltage transients safely to ground. Examples would include the power surges created by lightning strikes. But if the ground line rises, as it does in ground loop situations, you need isolation. Isolators stop transients by converting data signals to either pulses of light or an electrical field, then back again. Data passes through; transients don’t. But......

USB is invaluable, but it reveals some serious weaknesses when you take it out of the safe home/office environment and use it in real world applications. USB is very susceptible to ground loops, electromagnetic interference (EMI), and electrostatic discharges (ESD). Its effective range is just five meters; 30 meters if you add USB hubs. Standard USB ports don’t grip cables firmly, and if they wiggle loose it can cause data loss and even arcing. And USB was not designed to communicate with devices that employ older data communications protocols....

Industry: Industrial Automation & Manufacturing Product: USB Isolators The Challenge When technician John Baker of Premier Resource Services connected his laptop to a customer’s piece of industrial machinery he got a nasty surprise. There was a quick puff of smoke, and John lost his hard drive, his USB port and the USB adapter that he’d connected to the machine. The problem, he soon discovered, was that while his laptop was plugged into the wall, the machine he was servicing was connected to the shop’s single-phase power supply and its leads had been reversed to......

Industry: Medical Product: USB Isolators The Challenge Medical system designers who want to take advantage of USB’s plug-n-play, hot swappability, and robust peripheral support must factor in isolation for safety concerns. At least two independent isolation systems are normally required. Some systems must comply with the IEC60601 standard: isolation at all interfaces and peripherals at patient points of contact. The problem, he soon discovered, was that while his laptop was plugged into the wall, the machine he was servicing was connected to the shop’s single-phase power supply and its leads had been reversed to......
