Monitoring relays

Electrical safety for each application

Monitoring relays

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. All this by using monitoring relays!

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.
