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!

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.

• Short set-up and commissioning times for the monitoring relays, thanks to quick and easy knob adjustment (push & turn)
• Error-proof: Menu-based configuration of the monitoring relays with internal cross-referencing
• Ease of handling when exchanging device because configuration is saved on chip card
• Minimal standstill times thanks to extended diagnosis and measurements indication via display
• Approved for applications worldwide

1. Rapid installation: Innovative spring-loaded terminals, chambers are operated individually
2. Convenient diagnostics and parameter setting via the display: All relevant values can be set, displayed and retrieved
3. Rapid assembly via spring clips: No need for tools
4. Diagnostics in seconds: Via 6 LED displays – no external measuring devices required
5. Safe from manipulation: Setting elements have a lockable cover
6. Set values are saved on the chip card: Maximum flexibility when exchanging units
7. Safe from manipulation: Setting elements have a lockable cover

• On drives and motors: for load control, detection of wear and tear and preventive maintenance.

• To check for dry running or pump blockage.

• To monitor consistency and control quantities on mixers.

• To control the brush pressure on car washes.

• To monitor conveyors for blockages or wear and tear.

• Clinical operation zones with insulation monitoring: Use insulation monitoring in hospitals. In operating theatres, for example, preventive maintenance and advance information can help to achieve greater availability.

• Offshore installations such as wind turbines, clarification plants and shiplifts.
