Power Relays for Circuit Boards
A circuit board power relay is a board component that turns on / off an electric circuit to receive an external signal and transmits it to the next device. There are two types of power relays for circuit boards, and contact relays turn on and off by physically opening and closing the contacts, and are characterized by physical insulation. Another non-contact relay, which has no contacts and transmits signals by the function of an electronic circuit, is characterized by its small size, light weight, maintenance-free, long life and quietness. The product is widely used in industrial equipment such as machine tools, molding machines, industrial robots, power supplie units, etc. such as UPS and switched-mode power supplies, and factory automation equipment such as timers, programmable controllers, etc. Some are used for safety switches and emergency stops.
