What are the functions of safety control relays

Safety control relays are automatic switching components with isolation function. When the change in the excitation amount in the input loop reaches a specified value, the automatic circuit control device that can make the controlled power in the output loop undergo a predetermined step change. It has an induction mechanism that can respond to a certain amount of external excitation (electrical or non-electric), an actuator that can control the "on" and "off" of the controlled circuit, and can compare, judge and convert the magnitude of the excitation The intermediate comparison agency. Relays are widely used in remote control, telemetry, communication, automatic control, mechatronics and aerospace technology, and play the role of control, protection, regulation and information transmission.

Safety relays control the operation or stop of electrical related equipment.

Function and application:

In central air conditioning control systems, relays are often used as switches for power circuits such as compressors, fans, motors, water pumps, and four-way valves. When in use, one end of the safety control relays control coil is connected to the power supply, and the other end is connected to the output end of the control component. Through the output control signal of the control component, the safety control relays control coil generates a potential difference at both ends of the control coil and forms a current loop to generate electromagnetic force. Under the action of the electromagnetic force and the inherent elastic force of the relay reed, the relay contacts are attracted or released, thereby connecting or disconnecting the circuit of the electrical load power supply to control the operation or stop of the related equipment.
