Power Requirements
The XPress DR device server is normally powered by the same 12 VDC or 24 VDC supply that
powers other devices in your panel. Many AC-powered industrial controllers also supply 24 VAC
for use by field devices. The XPress DR is not shipped with a separate power supply, but any
power supply with a Limited Power Source (LPS) between 9-30 VDC or 9-24 VAC can be used.
The unit requires a maximum of 3 Watts.
