    Introduction

    The Eastron SDM320D/A DIN rail single phase two wire energy meter with S0 pulse output. SDM320D has LCD display, and SDM320A has analog display, based on kWh. The meter is provided with a non-volatile memory system that ensures that the readings are not lost or altered when power off. The meter allows up to 100A direct load in single phase application. It is perfect measuring instruments for AMR system or Energy monitoring and control system.

    Pulse output

    The SDM320D/A DIN rail energy meter is equipped with a pulse output which is fully separated from the inside circuit. That generates pulses in proportion to the measured energy for accuracy testing. 

    The pulse output is a polarity dependant, passive transistor output requiring an external voltage source for correct operation. For this external voltage source, the voltage (Ui) should is 5-27V DC, and the maximum input current (Imax) is 27mA DC. To connect the impulse output, connect 5-27V DC to connector 6 (anode), and the signal wire (S) to connector 5 (cathode). The meter pulses is indicated on the front panel.
