Power Supply Wiring
Below section describes the available power supply types for the D050-A. Which types are
available in your particular D050-A depends on the ordering code.
Battery equipped models switch their internal battery off when an external supply is active.
The following power supply options are available:
• Battery powered. see "Battery powered type PB" on page 9 for details.
• Input loop powered, see "Loop Powered Pressure Indicator Input Wiring Option Type A-PL" on
page 12 for details.
• Externaly powered, see ""External Power Supply wiring" on page 9" for details.
Battery powered type PB
Type PB is internally battery powered and does not require any external wiring.
When power supply PX is available (see below) the internal battery is switched off. This extends
battery life and guarantees higher availability during power outages.
• A healthy battery has a life expectancy of several years, depending on its use and
configuration settings. For details see "Battery life" on page 26.
• When installing verify that the battery is in good working condition by running the power-up
sequence on page iv of this manual. If the battery needs to be replaced follow the battery
replacement instructions delivered with the new battery.
External Power Supply wiring
The D050-A can be equipped with a power supply, type PX or PD.
• For type PX or PD DC your D050-A must be equipped with a 6 pole connector.
Type PD can also power your pressure sensor in the field, see "Power supply" on page 4 for
details.
Note:
• Type PX < 16V does not foresee in the (optional) backlight power; see "Backlight" on
page 11.
• The internal battery is on standby, when external power is supplied. Note that the
internal battery cannot be used to power a pressure sensor with 8.2V (pin S4)!
Caution:
The D050-A and it’s field devices are functionally isolated to a maximum of 500V!
