Description
Relays are electromechanical switches that are commonly used in digitally controlled kilns to regulate the amount of power sent to the heating elements. When the relay is activated, it allows electricity to flow to the elements, heating them up. The clicking sound you hear during firing is the relay turning on and off.
It's essential to use the correct relay for your kiln. While many kiln manufacturers use similar relays, it's crucial to verify that you're replacing the relay with one that matches the specifications of your kiln. This typically involves checking the rating numbers listed on the relay itself, which indicate the maximum amperage it can handle and the voltage required to power its control coil.
In the case of the relay described, it is rated for 30 amps and operates with a control coil powered by 12 volts DC, which is the typical output voltage from a digital control board in kilns. It's essential to ensure compatibility with your kiln's specifications to avoid any potential damage or malfunction.
