| SAT400 AC Input Optocoupler DESCRIPTION The SAT400 consists of a phototransistor optically coupled to a pair of light emitting diodes for AC input operation. Optical coupling between the input LEDs and output phototransistor allows for high isolation levels while maintaining low-level AC signal control capability. The SAT400 provides an optically isolated method of controlling many interface applications such as telecommunications, industrial control and instrumentation circuitry.
