It is possible to detect, with reference to the electric line and load connected to its: RMS voltage, RMS current, active power, reactive power, cos, frequency, energy.

A FeRAM allows to recovery the energy if a black-out occurs.

Energy counter: pulse digital output, reading on Modbus register.

It is possible to change electrical start/end scale by Dip-switch (see table 1, for each type of retransmitted output) or by Modbus registers (every value).

Normalized start/end scale between 0..+10000 (for RMS voltage, RMS current, active power), 350..750 (for frequency) or between 0..+10000 (for absolute values of reactive power, cos. isn’t possible to associate a normalized value to the energy quantity.

Possibility for connection and management by an external Current Transformer (only if Z203-1 is configurated by a configuration software).

Configuration of the module (node) address and baud-rate by Dip-Switches.

Configuration of the electrical-network nominal frequency, output type, retransmission scaling and retransmitted output by Dip-Switches.

It is possible to add/remove the module to/from RS485-bus without disconnecting the communication or power supply.

It is possible to switch automatically RS485 to RS232 or vice versa.
