Description
Increasingly higher demands are being placed on safety and
system availability – across all sectors. Processes are
becoming more and more complex, not only in mechanical
engineering and the chemical industry, but also in plant and
automation technology. Demands on power engineering are
also increasing constantly.

Error-free and therefore cost-effective operation can only be
achieved through continuous monitoring of important network
and system parameters. Electronic monitoring relays in the
EMD series are available for a wide range of monitoring tasks
to avoid the consequences of errors or to keep them within
limits.
The operating states are indicated using colored LEDs, errors
that may occur can be sent to a control system via a floating
contact or can shut down a part of the system. Some device
versions are equipped with startup and response delays in
order to briefly tolerate measured values outside the set
monitoring range.
WARNING: Risk of electric shock
Never carry out work when voltage is present.
Make sure you always use the the latest documentation.
