Saia PCD® S0 impulse counter
S0 Collect, convert and transmit pulses
If already installed meters, which are not bus-capable, are to be integrated into an automation system, the Saia PCD7.H104 S0 pulse
counter is the easiest way. This is the case for refurbishments, for example, if the existing meter infrastructure has to be made bus-capable
and there is no question of buying new meters. With this S0 pulse counter, meters (electricity, water, heat, etc.) with an S
0
pulse output
from any manufacturer can be connected directly using a serial RS-485 S-Bus or Modbus connection to the Saia PCD, the e-Monitor or
any controller. 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 valence of pulses can be trans-
mitted.
