Phoenix Contact Monitoring Relay, 3 Phase, DIN Rail, 480 V ac

The Phoenix Contact Monitoring relay monitoring the phase sequence and asymmetry of 3-phase voltages at 208 - 480 V AC / 120 - 277 V AC. It is only by continuously monitoring key network and system parameters that error-free and therefore cost-effective operation can be achieved.Electronic monitoring relays from the EMD series are available for a wide range of monitoring tasks so that the consequences of errors can beavoided or kept within limits. The operating states are signaled via color LEDs and any errors that occur can be sent to a controller via a floating contact or can shut down a section of the system. All device versions are equipped with response delays so that measured values outside the set monitoring range can be briefly tolerated.
