Overview

Z728 Single Channel
Solenoid Valves,The simplest and most cost-effective solution is a single channel Zener barrier with the power supply grounded on the safe side.,LED's,If the nominal power supply is low enough the barriers end-to-end resistance limits the current flow to the LED, otherwise a current limiting resistor is required.,Audible Alarms,Audible alarms work with relatively high voltage and low currents and are approved in conjunction with the zener barrier. The circuit represents the simplest possible solution.,28V, 300Ω single channel, positive polarity zener barrier. Typical applications: solenoids, LED's, audible alarms, etc.
