What is the voltage of the SmartWire-DT system?

SmartWire-DT uses 15Vdc for the powering all the nodes (including the pilot device LEDs) and the communication protocol. In
addition, SmartWire-DT also transports 24Vdc power for the contactor coils. The 15Vdc is generated by the gateway and powerfeed modules from a separate 24Vdc power supply.
