1.4. Power Module
The
Dust Sentry Pro
internal power requires regulated 12 VDC to maintain a constant pump speed.
An external mains to 12VDC power supply (Meanwell HLG80-12A 60W 12V) is fitted on the outside
of the enclosure and this will allow connection to mains supply.
Note: If you wish to run the
Dust Sentry Pro
on solar power you will need to use a DC-DC
convertor in order to supply a regulated 12 VDC for the
Dust Sentry Pro
– refer to the
application notes on the website
1.5. Analogue Output Module (Optional)
The Dust Sentry has the option to integrate an ADAM 4021 Analogue Output Module into the system
to allow for the digital inputs of a chosen sensor to be converted to an analogue output. The analogue
output module receives the digital input via an RS485 interface and converts it to a 4-20mA and 2-
10V output. These outputs follow each other.
Outputs:
4mA (2V) = 0% of full scale value.
12mA (6V) = 50% of full scale value.
20mA (10V) = 100% of full scale value.
The module is easily configured via the Operations menu in the PC software and can convert to an
analogue output any chosen sensor already integrated in the Dust Sentry. The module uses the
logging period to calculate the reading, which is also set in the Operations menu. This differs from the
alarm relay, SMS and email which all use the averaged alarm period to calculate the reading. For
more information regarding the PC Software and setting up the analogue output module please refer
to Section 3.1.
1.6. Auxiliary Module (Optional)
The auxiliary module acts as an interface between third party sensors and the
Dust Sentry Pro
communication bus. It is configured with different operating modes which can be selected by using
the dipswitches located on the side of the module. Aeroqual has integrated a number of third party
sensors and is able to supply the auxiliary module preconfigured for your sensors.
