Phoenix Contact monitoring relays are reliable safety components that enable continuous monitoring of key parameters in industrial and power installations. Thanks to the use of EMD series monitoring relays, it is possible to detect irregularities at an early stage, prevent failures and automatically shut down endangered areas of the system.

The solutions offered by Phoenix Contact enable a quick response in the event of exceeding or falling below a set limit value, which significantly increases system availability and reduces costs associated with downtime or damage.

Why choose Phoenix Contact monitoring relays?

• Effective protection of installations thanks to wide functionality and compact design,
• Early fault detection as soon as faults occur – short response times,
• Quick wiring and space-saving installation in switch cabinets,
• Relay outputs for automatic shutdown or error signalling,
• Continuous monitoring of parameters – electrical and physical – for increased process reliability.

Phoenix Contact offers two main product groups:

Compact monitoring relays EMD-BL

These are the ideal solution for simple monitoring applications, especially in building installations and series production of machines and devices. They are characterised by their compact design, easy installation and trouble-free integration in confined spaces.

Multifunctional control relays

For more demanding applications, Phoenix Contact offers multifunctional EMD monitoring relays, which enable monitoring of a wide range of parameters, such as voltage, current, phase asymmetry and frequency. Thanks to their extensive setting options and different supply voltage variants, they are ideal for complex automation and power engineering systems.
