Current Output Connections
Standard Current Outputs
There are three current outputs on the WDG-V UOP Analyzer. The current out-
put connections are labeled as follows on the
Sensor
board terminals:
Analog Output #1 => +I1-
Analog Output #2 => +I2-
Analog Output #3 => +I3-
The current outputs are referenced as Analog Outputs 1, 2, and 3 in the
AMEVision Display User Interface and PC Configurator Software.
Observe the polarity when connecting current output devices to these
terminals.
Each current output is capable of driving up to a 1000 ohm load.
The current outputs can be selected for the following ranges:
0
–
20 mA
4
–
20 mA
NAMUR
The NAMUR outputs are implemented as follows:
4–20 mA signal Analyzer Condition
0 mA Analyzer unpowered, or completely failed.
3.5 mA Critical Alarm – analyzer reading unusable (factory default).
3.8 mA Reading Under Range
(Example: User sets range to 2–10 %.)
Current reading is 1.9 %.
4–20 mA Normal Operation
20.5 mA Reading Over Range
(Example: Range is 0–10 %.)
Current reading is 12 %.
