Electronic monitoring relays PMDsrange from PILZ

S1MS+S3UM+S1PN ISO

Reliable electronic monitoring and control of plant and machinery is at the heart of PILZ range of monitoring relays.

On electronic monitoring relays, electrical safety is the focus. When monitoring voltage, current, temperature or similar variables, for example. Reduce the number of hazardous situations for man and machine while at the same time increasing the service life of your plant. Save costs and guarantee an efficient production cycle. All this by using electronic monitoring relays PILZ. These multifunctional, universal relays cover a wide range of applications.

PMDsrange electronic monitoring relays can be identified by their green housing. The newer generation of PMDsrange relays in 22.5 mm housing offer technical features which guarantee that products can be perfectly tailored to your application.

In addition to current, voltage and insulation monitors, the range also includes relays for true power, phase sequence and thermistor monitoring. Quick and easy installation, practical terminals, a variety of operator elements as well as luminous displays all help to make commissioning easier.
