Monitoring relay for monitoring 3-phase voltages of 160…300 V AC, undervoltage, window, phase

sequence, phase failure, asymmetry, wide-range power supply unit, 2 PDTs

Product 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.
