Saia PCD®
S0 pulse meters
Collecting, converting and transmitting S0 pulses
If already installed meters, which are not bus-capable, are to be integrated in an automation system, the Saia PCD7.H104 S0 pulse meter
is the easiest way. This is the case for refurbishments, for example, if the existing meter infrastructure has to be made bus-capable and
new meters are not simply purchased. With this S0 pulse meter, meters (electricity, water, heat, etc.) with a S0 pulse output from any
desired manufacturer can be connected directly to the Saia PCD®, E-Monitor or any desired controller via a serial RS-485 S-Bus or Modbus
connection. This enables efficient transfer, evaluation and forwarding of energy data without additional complicated coupler modules.
For connection to Saia PCD® systems, there are ready-made FBoxes. Via the interfaces, the number or weights of pulses can be transmit-
ted.
