Power supply
The power supply provides controlled voltages for inputs and outputs. The room automation stations also supply AC 24 V field supply. The supply is located in the device to simplify wiring and diagnostics.
The processor controls the power supply. This ensures clean conditions for field devices connected to the I/Os during startup, shutdown, and undervoltage.
