Powerfeed modules feed auxiliary 24 VDC power and/or 15 VDC network power into the SmartWire-DT flat cable. The auxiliary 24 VDC power is needed for the power supply of contactors and the 15 VDC network power is used for supplying power to additional SmartWire-DT nodes. Powerfeed modules are also used to create zone control or groups of devices controlled by a single Emergency Stop.
