4.9 Description of the outputs
4.9.1 Current output
• All outputs are electrically isolated from each other and from all other circuits.
• All operating data and functions can be adjusted.
• Passive mode: external power U
ext
≤ 32 VDC at I ≤ 22 mA
• Active mode: load impedance R
L
≤ 750 Ω at I ≤ 22 mA
• Self-monitoring: interruption or load impedance too high in the current output loop
• Error message possible via status output, error indication on LC display.
• Current value error detection can be adjusted.
• Automatic range conversion via threshold. The setting range for the threshold is between 5
and 80% of Q
100%
, ± 0...5% hysteresis (corresponding ratio from smaller to larger range of
1:20 to 1:1.25).
Signaling of the active range possible via a status output (adjustable).
• Forward / reverse flow measurement (F/R mode) is possible.
INFORMATION!
For further information refer to Connection diagrams of outputs on page 39 and refer to
Technical data on page 77.
DANGER!
For devices used in hazardous areas, additional safety notes apply; please refer to the Ex
documentation.
