Connecting one or more SmartOutput modules - SmartRelay 3 system

SmartOutput modules require a supply voltage which may differ from the controller's supply voltage. For this reason, it is recommended to use their own power supply unit. SmartOutput modules are connected in parallel on the bus (A, B). The bus is connected to the controller instead of a third reader. To ensure the SmartOutput modules are activated correctly, an address needs to be configured on each SmartOutput module (see SmartOutput module manual).

NOTE

notice

If the controller's power supply unit delivers 12 VDC and sufficient electricity, there is no need for a power supply unit for the SmartOutput modules; the controller's power supply can be used instead. In this case, the earth system in the SmartOutput modules is connected to the controller power supply unit and VIN in the SmartOutput modules with the power supply unit's 12 VDC.
