This range of multifunctional monitoring relays allows to monitor electrical as well as physical system parameters.
EMD Monitoring Relays can measure:

Currents
Voltages, 1- and 3-phase
Phase sequences
Real powers
Loads, cos φ
Motor winding temperatures
Fill levels

Looking for a way to ensure safe voltages in your electrical setup? Choose this voltage monitoring relay from Phoenix Contact. It uses built-in colour-coded LEDs to alert you to power supply issues like undervoltage, phase failure or phase asymmetry, so monitoring is simple. It's designed for mounting in any position on a DIN rail for simple and versatile installation.
The terminal block has a fast-blow 5A fuse that instantly breaks the circuit in the event of an excessively high current, helping to protect you and your equipment against dangerous power surges. To suit the needs of your system, you can set a response delay time between 0.1 and 10s. Thanks to its broad input voltage range of 177 to 794V AC, this unit is suitable for use in a wide variety of electrical setups.
