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. Accurate measurement. It is compliant with the international accuracy standard IEC/EN62053-21, and the IEC/EN61557-12 performance requirements (active power and active energy). Legal metrology, guaranteed by the MID approval Wireless communication, wireless M-Bus version allows remote data collection when cabling is not possible Description due to cost or installation requirements. Easy commissioning of wireless communication thanks Three-phase energy analyzer for DIN-rail mounting to the test function of the joystick and to transmission with configuration joystick, frontal selector and counter for diagnostics. 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. The wireless M-Bus version is the perfect solution when cabling is not possible. Applications EM24 is the perfect solution in any application, specially in building and industrial automation where energy and main electrical variables monitoring is required. EM24 is particularly suited for: energy efficiency monitoring cost allocation fiscal/legal sub-billing, where the wireless M-Bus version is the best choice for quick and easy installation without cables. Encryption ensures data security and safeguards confidentiality . 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). 18/11/2020 EM24 DS ENG Carlo Gavazzi Controls S.p.A. 1EM24 Transmission of energy consumption via pulse output (optional). Easy connection function. Transmission of data via wireless M-Bus (868 MHz for the European market). Two wireless M-Bus versions: a compact model with internal antenna and a SMA connector model with external antenna (in case of metallic switchboard). Main features Energy measurements: total and partial kWh and kvarh or based on 4 different tariffs single phase measurements Gas, cold water, hot water, kWh remote heating measurements via digital inputs TRMS measurements of distorted sine waves (voltages/currents) Data encryption (a unique key will be provided for any device in a sealed envelope included in the instrument box) Compliant with IEC/EN61557-12 performance requirements (active power and active energy) Structure Fig. 1 Direct connection Fig. 2 CT connection 18/11/2020 EM24 DS ENG Carlo Gavazzi Controls S.p.A. 2
