Relay is an automatic switching element with isolation function, which is widely used in remote control, telemetry, communication, automatic control, electromechanical integration and power electronic equipment. It is one of the most important control elements. The relay generally has an induction mechani...
The larger contacts give them the ability to withstand unexpected surge currents caused by parasitic capacitances present in your circuit, cables, etc. An unfortunate tradeoff, however, is that the larger contacts require larger package sizes so they cannot be placed as densely on a switch module...
Arduino Relay Circuit Arduino Relay Operation This circuit works in two cases like turning on/off a load with a relay & a button. Once the button is pushed then the Arduino board will set pin-2 in HIGH condition, which means 5 volts on pin-2 of board. So this voltage is mainly utiliz...
If the device functions as the DHCP relay and is connected to a DHCP snooping-enabled device, you are advised to configure the rate limiting function on the DHCP snooping-enabled device. You can configure the rate limiting function in the system view, VLAN view, or interface view. The ...
If a diode is not available a high value electrolytic capacitor can be also used. The capacitor can function in the same way. It allows a reverse short circuit path for the back EMF and protects the transistor from getting damaged.
