Bus switching relay (230V/16A) for implementing NO/NC circuits. Copies the state of a switching output signal, the armed state of an area or an alarm triggered in an area of the System 9000 alarm system. The signal to which the relay responds is set using a DIP switch on the circuit board. Does not occupy an address in the system and must be housed in a 9000BD1 mounting box. Operating voltage via bus. Power consumption when switching off: 5mA, power consumption when switching on: 45mA, I-calc =45mA. Load capacity with resistive load (cos =1): max. 16A / 230V. Load capacity with inductive load (cos = 0.4): max. 8A / 230V. Halogen lighting: max. 1KW. Minimum DC load: 0.5W. Protection class 2, dimensions: 70 x 38 x 20mm.
