What are optocouplers? What is optical isolation?
Optocouplers are a form of optical isolation that employs light to transmit information across an isolation barrier. Typically, a light emitting diode (LED) transmits information to a light sensitive receiver (e.g., a transistor). Optical i... Read More »

How a lightning can affect a optical isolated RS 485 bus?
Because of the very high voltage of lightning, an opto isolator can't block it, the best is to relay any lightning to ground but that is still not a guarantee that the spike will be stopped. Lightning voltage is in the Giga Volt range. Read More »
