Radio switching relay for the top hat rail for switching loads up to 16A/230V. Copies the state of a selected switching output of the System 9000. The switching output (1 to 4) to which the relay responds is set via the software. Occupies an address in the system. Is mounted on a DIN top hat rail. Alternatively, the relay can be used as a standalone radio relay without a control panel with the system detectors 9000M, 9000P, 9000R4 (64 per relay). 5 operating modes (copy/status, pulse, state change, deactivate, block) can then be set. Programming must be done via software and control panel. No support via a radio repeater 9000FR. Power supply via L, N conductor (230V). Load capacity with resistive load (cos(phi) =1): max. 16A / 230V. Load capacity with inductive load (cos(phi) = 0.4): max. 8A / 230 V. Halogen lighting: max. 1KW. Minimum DC load: 0.5W. To be used with antenna 9000ANT1. Galvanically isolated according to protection class 2. Dimensions: 18 x 90 x 65mm, one DIN unit.
