Analogue actuator, 4-gang for KNX DRA plus Features: 4-gang DRA analogue actuator with integrated bus coupler converts KNX telegrams (1-byte and 2-byte) into analogue output signals. These analogue output signals enable heating, air conditioning and ventilation actuators to adapt their initial parameters based on bus information, and to participate in control processes. Voltage outputs with short-circuit protection. The initial state is indicated by the status LED. The initial parameters can be restrained. Switch off outputs not required. The four outputs are parameterised to voltage or current signals by the software.
