Saia PCD® energy meters with SBC S-Bus interface
The energy meters with integrated S-Bus interface offer all relevant data such as energy, current, voltage, out-
put (active and reactive) and cosφ, which can be read out through the bus connection.The serial S-Bus interface
(based on RS-485) can be connected directly to the Saia PCD® range of devices. For this connection, there are
ready-made FBoxes for every meter type, which are available free of charge. The S-Bus energy meters are also
available in a two-way design (bidirectional). On the display, the bus address can be set and the energy, current,
voltage and active output can be read directly.
