E72..-01 PULSE TRANSMITTER (E7... -5 and E7... -9 ) PURPOSE AND APPLICATION: Pulse transmitters (series -5 and series -9 ) can be built into single-phase electricity meters, accuracy class 2. They are used for generating and transmitting pulses to tariff devices, for summing up, inspecting, recording as well as data processing, for reasonable consuming and billing electric energy. Pulse frequency is proportional to meter rotor speed as well as to electric energy consumption. Transmission of pulses from the meter to the central unit is performed through special two-wire lines. STANDARDS : Pulse transmitters are made in compliance with DIN 43 864 standard and IEC 1036, Articles 5.5.2. to 5.5.5.;.
