Designed to monitor voltage, current, temperature, and phase sequence, PMDsigma Relays enable users to set values via rotary knob and save them to chip card. Data remains flexible and can be copied to other units. Model PMD s10 monitors true power of motors with rating up to 11 kW, and can process frequencies from 0-1,000 Hz, making it suitable for dc and ac motors as well as frequency-controlled drives. With relays, users can implement early warning system for hazardous plant conditions.

Electrical Safety Made Simple. With The New Pmdsigma Monitoring Relays, Users Are In Control
The new generation of PMDsigma electronic monitoring relays from Pilz monitors values such as voltage, current, temperature and phase sequence. One new feature on PMDsigma is the ability to set values simply 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 while also providing user-friendly diagnostics. The first unit in the PMDsigma product range monitors true power. This provides an early warning system for hazardous plant conditions, with no requirement for additional sensors.
The compact unit PMD s10 provides an indication of the motor load through the true power. It monitors the thresholds, while at the same time providing an analog voltage or current value, which is proportional to the true power. This means that both the overload and underload thresholds can be monitored via an analog signal (PLC) or via the integrated relay.
True power easy to monitor. - Motors with a rating of up to 11 KW can be monitored directly; larger motors can be monitored via current transformers. Motor voltages of up to 550 V are possible. The PMD s10 can process frequencies from 0 Hz up to 1000 Hz. It is therefore very flexible and is suitable for DC and AC motors as well as frequency-controlled drives. Motor start-up and transient power fluctuations can be suppressed so that high inrush currents do not affect the unit. Peak values during operation can be stored and called up via the display. While the operation is running, the unit can display up-to-date values such as current power consumption. An integrated operating hours and cycle counter enables preventive maintenance, thereby reducing repair and downtimes.
Economical early warning system. - With the PMD s10, users can implement an early warning system for hazardous plant conditions, without the need for additional sensors. Filter plugging or wear and tear on mechanical components such as bearings can be identified before they lead to failure. So expensive mechanical damage, downtimes and personnel hazards can all be avoided. There are various application examples for true power monitoring with PMDsigma: controlling the brush pressure on car washes; monitoring tools and conveyors for wear and tear; monitoring conveyors for blockages, and inspecting sieves and fans for contamination.
