Monitoring relays

Electronic monitoring relays PMDsigma

On electronic monitoring relays, electrical safety is the focus. Monitoring relays reduce the number of hazardous situations for man and machine and increase the service life of plant and machinery. Save costs and be sure of an efficient production cycle. With monitoring relays, the priority is the protection of persons and the machinery against insulation faults, residual voltages, overvoltage, overcurrent, overload, temperature overload as well as monitoring standstill and true power. Significantly reduce 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. These monitoring relays are multifunctional and can be applied universally, covering a wide range of applications. You can use PMD monitoring relays to meet the requirements of IEC 60204-1 for the safety of electrical equipment on your machines.

Insulation monitoring: The insulation monitor PMD s20 can be used to monitor the insulation resistance of unearthed AC/DC systems. Thanks to the separate supply voltage, monitoring of the de-energised system is possible. True power monitoring: Using the measured true power, it is possible to derive variables such as fill level, volume, torque or air pressure, for example.
