Can A Dc Relay Be Used With Ac at Kaitlyn Corkill blog

Can A Dc Relay Be Used With Ac. Depending on the type of relay the coil can be designed for either ac or dc current and the switch contacts can be rated for ac or dc current and voltage, or they can be. Is it safe to do it this way? Will the relay stop working? A relay coil designed for dc operation will not work with an ac. You can try, but all that will happen is the relay will buzz with no motion on the armature. As a result, an electromechanical relay or electric switch rated for a specific ac voltage and current may not be compatible with the same dc voltage and current. The dc relays have a much bigger coil because the resistance must be high or you just shortciruit. Typically, the contact current and voltage rating will actually be higher for ac. I want to use a 24 v dc relay with 24 v ac. Since alternating current decreases to zero. In theory, then, ac can be used to operate a dc relay. In reality, however, doing so is impractical. Yes, that's an entirely common scenario. You should never use an ac relay for dc. Using dc relays for switching ac loads is much less problematic, but you can usually find a cheaper ac relay which does not.
