Power Requirements
As with most industrial automation devices, the XPress DR+ does not ship with a power
supply. Its flexible power input circuit allows the product to be powered by any 9-30 VDC
or 9-24 VAC power supply that can provide the 2.3-Watt maximum required by the
XPress DR+.
In addition to the wide power input range, the XPress DR+ provides:
‹ 2K VAC and 2.8K VDC galvanic isolation between the power input and the
Ethernet ports
‹ 2K VAC and 2.8K VDC galvanic isolation between the power input and the serial
ports
Reset Switch
The XPress DR+ includes a hardware reset switch located in the small hole above the
power connector. Pressing the reset switch provides a hardware reboot of the XPress
DR+. The hardware reset does not reset or change the configuration of the XPress DR+.

Caution: Even though a chassis ground is not required for operation, it is
mandatory for protection against transient voltages and ESD. A chassis
ground must be connected to earth.
