The 4 - 20 mA sensor is the de facto industry standard. This section details how to configure the Q5 to accept
this type of input. As the Q5 does not power current loops, external power will need to be provided in order for
your current loop to function.
To utilize this feature the hardware jumpers must be configured in Current Mode (see section 2.0). Next,
configure the input from the Analog Inputs menu. The Channel Mode and Measurement Type must be configured
as shown below. The configuration example below shows a 4 - 20 mA sensor with a range of 0 - 150 PSI. The
sensor range for the specific sensor must be entered as shown in the red boxes.
Hardware configuration example for a 4 - 20 mA sensor.
Current transformers can also be used
with the Q5 without the need for
additional
conditioning. Current
transformers are connected as shown
above.
Note: Current transformers are not to
be confused with the 100A non-
invasive current sensors sold by
FlexSCADA. The non-invasive current
sensor converts current readings into a
0-5V voltage style reading. See sec 2.1
WARNING! EXCEEDING THE CURRENT RATINGS OF THE Q5 WILL DAMAGE YOUR DEVICE AND VOID THE WARRANTY!
