Power supply

Order characteristic for
"Output"
Option C
1) When using only one output: use output 1.
An external power supply is required for each output.
Order characteristic for
"Output"
Option C
1) External supply voltage of the power supply unit with load (® ä 21)
• Operation with output 1: 65 to 660 mW
• Operation with output 1 and 2: 130 to 1 320 mW
3.6 to 22 mA
If the option Defined value is selected in the Failure mode parameter (® ä 96):
3.59 to 22.5 mA
• Totalizers stop at the last value measured.
• Configuration is retained in the device memory (HistoROM).
• Error messages (incl. total operated hours) are stored.
(® ä 22)
No special measures for potential equalization are required.
Plug-in spring terminals for wire cross-sections 0.5 to 2.5 mm
• Cable gland: M20 × 1.5 with cable Æ 6 to 12 mm (0.24 to 0.47 in)
• Thread for cable entry: NPT ½", G ½"
• Permitted temperature range: –40 °C (–40 °F) to ³ 80 °C (176 °F)
Minimum requirement: cable temperature range ³ ambient temperature + 20 K
• A normal device cable suffices if only the analog signal is used.
• A shielded cable is recommended if using the HART protocol. Observe grounding concept of the
plant.
