EM24 Energy analyzer for three-phase systems Benefits Time saving set-up, by frontal joystick and selector. Error-proof installation, by self-power supply and phase sequence detection. Easy variable scrolling, by means of the front joystick. Wide interfacing capability, choosing among 2 pulse outputs, the RS485, the M-Bus, Dupline or the Ethernet communication port. Extended energy measurements, using total/partial or total/multi-tariff metering. Flexible installation, by means of the direct connection up to 65 A or the connection of 5 A current transformers. Extended alarm control on any available variable by means of up to two digital outputs. Legal metrology, guaranteed by the MID approval Description Three-phase energy analyzer for DIN-rail mounting with configuration joystick, frontal selector and LCD display. Direct connection up to 65A or via current and voltage transformers. It can be equipped with 2 digital outputs (pulse transmission or alarm function). In alternative the Modbus RTU or Dupline communication port and 3 digital inputs, the M-Bus communication, or the Modbus TCP/IP Ethernet ports are available. Applications EM24 is perfect solution in any application, specially in building and industrial automation, for cost allocation, and for energy efficiency monitoring, legal submetering in commercial and residential installations, and wherever energy and main electrical variables monitoring is required. EM24 is particularly suited for: energy efficiency monitoring cost allocation fiscal/legal sub-billing Main functions Measurement of energy consumption and main electrical variables of single-phase, two-phase or three-phase loads. Display of single phase measurements and total measurements. Transmission of data via serial communication (Modbus RTU, M-Bus or Dupline) or Ethernet (Modbus TCP/IP). Transmission of power consumption via pulse output (optional).
