Control relays | Choosing the Right Protection Relay
Protection relays can be divided into two main categories: digital relays and electromechanical relays. Digital protection relays Digital protection relays, also known simply as "digital relays", are made up of an electronic system with microprocessors. These microprocessors make it possible to analyze various grid parameters, such as voltage, intensity, or current to detect faults in an industrial control system. Thanks to microprocessors, these relays can...

    How to choose this product
    control-relay

    A monitoring relay is used to monitor and report values that exceed predefined parameters.

    Applications

    These devices can be used to monitor electrical parameters, such as power factor, voltage, current or phase. They also monitor manufacturing parameters, including temperature, pressure, levels and frequencies.

    Technologies

    As with other relays, monitoring models may be electromechanical, though most now are semiconductor-based solid state relays. Some are directly programmable and are presented in ISO cases for rail installation.

    How to choose

    Choice depends on the intended application and the parameters to be monitored.
