Input, output and communications wiring

WARNING
Unintended Operation
Be aware that an unexpected change of state of the digital outputs may result when the supply power to the meter is interrupted.
Failure to follow these instructions can result in death, serious injury, or equipment damage.

The digital outputs of PM3255 are polarity independent.

The digital inputs and outputs of PM3255 are electrically independent.

Pulse output (PM3210 only)

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

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

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