power supply. EM3-DIN is
provided with: 6+1DGT electromechanical indicator for
the indication of kWh or
kvarh; one green LED for the
indication of power ON; one
red LED blinking proportionally to the consumed energy.

Open collector output Fig. 1
Only open collector outputs: the grounds of the outputs are separated, and therefore it’s possible to carry out, for the same module,
two different connections. The load resistance (Rc) must be designed so that the closed contact current is lower than 100mA; the
VDC voltage must be lower than or equal to 30V.
