•The pulse output is compatible with S0 format.

•The pulse output can be directly connected to a 24 V DC (< 30 V DC) input on a Zelio or Twido PLC.

•The pulse output indicates the primary consumption with consideration of transformer ratios.

•For other concentrators, if V DC/Rin > 15 mA, add a resistor Radd = (V DC/0.01) - Rin Ω
