4.8 description of the inputs and outputs
information
The current outputs must be
connected depending on the
version! Which I/O versions and
inputs/outputs are installed in
your signal converter are indicated
on the sticker in the cover of the
terminal compartment.

For further information refer to
Description of the inputs and
outputs on page 25 and refer to
technical data on page 96.

For devices used in hazardous
areas, additional safety notes
apply.
4.8.1 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 Uext
≤
32 VDC at I
≤
22 mA
•
Active mode: load impedance RL
≤
1 k
Ω
at I
≤
22
mA; RL
≤
450
Ω
at I
≤
22 mA for Ex i outputs
•
Self-monitoring: interruption or load impedance too
high in the current output loop
•
Error message possible via status output, error
indication on LCI40 display.
•
Current value error detection can be adjusted. Default
setting: 3.6 mA
•
Automatic range conversion via threshold or
control input. The setting range for the threshold is
between 5 and 80% of Q
100%
, ± 0 to 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.
