The Phoenix Contact EMD-FL-V-300 is an electronic monitoring relay designed for single-phase voltage monitoring in industrial automation and power engineering applications. This relay monitors AC/DC voltages in the range of 0 to 300 V and provides configurable overvoltage, undervoltage, or window monitoring functions. It features an integrated wide-range power supply unit that accepts control voltages from 24 to 264 V AC/DC, two changeover contacts for switching applications, and front-panel potentiometers for adjustable threshold values. The relay includes error memory functionality, separately adjustable startup and response delays, and colored LED indicators for operating states. Suitable for DIN rail mounting, it is ideal for monitoring critical network and system parameters in mechanical engineering, chemical processing, plant automation, and control cabinet applications to ensure error-free operation and prevent costly downtime.
