Power supply
The power supply provides controlled voltages for inputs and outputs. The primary
automation stations also supply DC 24V (max. 100mA) 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.
Bus power supply
The primary automation station includes the bus power for KNX PL-Link. The bus power is
switched on by default, but can be switched off via web interface or configuration in the
Automation Building Tool (ABT).
The internal KNX PL-Link supply cannot be operated parallel to external power supplies. The
internal KNX PL-Link power must be switched off during the engineering phase for external
power. This is typically the case if the 50 mA from the internal supply is not enough to supply
all devices connected on the KNX PL-Link bus.
Type summary
The devices are supplied without terminal covers. The terminal covers must be ordered
separately. See Accessories.
