    What is the difference between safety relay and ordinary relay?

    The safety relay is applied to the safety circuit, which is a protective barrier for the equipment of the general control system. The safety relay can be multi-circuit protected and integrated, and even in the form of a safety plc; the safety relay circuit of a large system is an important link; Lat... read more

    What is the test method of the relay?

    1. Measuring contact resistance Use the resistance profile of the universal meter to measure the EBW Shunt Resistors of the normally closed contact and the moving point. The resistance value should be 0; and the resistance of the normally open contact and the moving point is infinite. It can be dist... read more

    What is the function of shunt resistor and how to choose?

    What is the role of shunt resistance Shunt Resistors is an important function of current sensing in electronic systems, but its complexity is often underestimated. Accurately measuring current flow is far less easy than measuring voltage, and it is even more difficult when trying to measure current ... read more

    What is a safety relay?

    The safety relay is a combination of several Latching Relays and circuits in order to complement each other's abnormal defects and achieve the complete function of the correct and low malfunction relay. The lower the error and failure value, the higher the safety factor. Therefore, it is necessary t... read more
