  • Page 129: Power Supply

    Power Supply Power Supply Module Bus Refreshing The number of BL20 modules that can be supplied by the gateway or a separate Bus Refreshing module via the internal module bus depends on the respective nominal current consumption of the indi- vidual modules on the module bus.
  • Page 130 Maximum permissible current via module bus: 1 500 mA The calculation shows that an additional/further Bus Refreshing module is required at the latest following the last BL20-2AO module. This Bus Refreshing module is sufficient to supply the remaining modules. Note The power requirements of the BL20 gateway is to be considered when calculating the required number of Bus Refreshing modules.
