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.
