  • What is the Safety Relay? Is the Safety Relay Good?

    What is the Safety Relay? The safety relay is the combination of several relays and circuits to complement each other’s abnormal defects in order to achieve the complete function of the relay with correct and low error probability. The lower the error and failure value is, the higher and safety f...

  • Electrical Symbols and Contact Forms of Relays

    The relay is composed of two parts, that is, coil and contact group. Thus, the graphic symbol of the relay in the circuit diagram also includes two parts, that is, a long box represents the coil, and a set of contact symbols represent a combination of contacts. When the circuit with few contacts ...

  • Measurements Taken to Test Relays

    1.Testing Contact Resistance We can use the multimeter resistance to measure the resistance of constant closed contact and moving point, its resistance value should be 0, and the resistance value of constant open contact and moving point is infinite. It is thus possible to distinguish between a n...
