Pilz Automation Safety L.P.'s PMDsigma electronic monitoring relays

ELECTRICAL SAFETY

PMDsigma electronic monitoring relays monitor values such as voltage, current, temperature and phase sequence. They offer the ability to set values via a rotary knob and then save them to a chip card. Data remains flexible and can be copied over to other units. A plain text display supports parameter setting. The relay monitors true power and provides an early warning system for hazardous plant conditions, with no requirement for additional sensors.
