Mayser Control Units analyse the output signals of our Safety Mats, Safety Edges and Safety Bumpers and immediately trigger the necessary safety measures. The functional monitoring of Mayser evaluation units is carried out according to different principles.

In the case of 2-wire technology, a constant closed-circuit current is measured by means of a monitoring resistor integrated in the sensor. If the sensor is activated, the voltage drops. The safety contacts of the Control Unit are opened and ensure safe shut-off of the drive.

In the case of 4-wire technology, functional monitoring is carried out by returning the signals to the Control Unit. Mayser Control Units comply with categories 1, 2 or 3 as per EN13849 and are available in different models depending on the area of application.
