The Gira Analogue Actuator 4-gang (1022 00) is a KNX actuator designed to provide four analogue output channels for compatible building-control equipment. In a KNX system, analogue outputs can be used where external devices require a variable control signal rather than simple on/off switching. The output ranges and electrical characteristics determine which valves, controllers or other equipment can be connected, so these must be verified before design or installation. ETS commissioning defines how KNX group objects control the outputs and how the actuator behaves within the automation logic. Review the current Gira datasheet for supported signal ranges, output load limits, wiring, supply requirements and installation conditions before selecting field devices.
