Bus switching module for 4 outputs of the System 9000. For controlling load relays, KNX input modules or other external controls. The outputs follow either the switching output signals of the control panel, the armed status of the areas or the alarm status in the areas. Output terminals 1-4 correspond to the switching outputs or areas 1-4. For installation in the control panel or a 9000BD1 mounting box. Potential-free outputs, not galvanically isolated. Does not occupy an address in the system. Power supply via bus. Supply voltage for external devices via U+ terminal 12V/100mA. Quiescent current consumption: 5mA/10mA (with switched outputs), I-calc =10mA. Load capacity per switching output: 100mA/38V. Dimensions: 77 x 40 x 15mm.
