Current Output Connections
Standard current outputs
There are three current outputs on the WDG-V UOP sensor. The current output
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 AMEVi-
sion Display User Interface and PC software. Be sure to observe the polarity
when connecting current output devices to these terminals.
Each of the current outputs are capable of driving up to 1000 ohm loads.
The current outputs can be selected for the following ranges:
0-20mA
4-20mA
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 to 20 mA Normal Operation
20.5 mA Reading Over Range (Example: range is 0-10%. Current reading is 12%)
