Overview
The Loadstar Sensors
DQ-1000 Single Channel
Frequency Interface provides
a simple and convenient
way for users to convert the
frequency output of an iLoad
Mini sensor to either a USB
digital output (DQ-1000U) or
analog outputs (DQ-1000A)
of 0—5 V DC and 0—20 mV.
When ordered together with
an iLoad Mini sensor, the
DQ-1000A can be calibrated
to the sensor to enable direct
0.5 V to 4.5V or compatibility
with legacy displays that ac-
cept 2 mV/V input.

Loadstar Sensors’ Model DQ-1000 Single Channel Frequency-to-Analog
Interface takes the frequency output from an iLoad Mini sensor and converts
it to two different analog outputs: a 20 mV/V ratiometric output and a 0—5 V
DC analog output.
Notes
Note that the 5V DC Signal, the 20 mV- and the EXC- are all connected to the common ground. 1.
If you are using the ratiometric 20 mV/V output, the recommended excitation voltage (EXC+) is 2.
+10V. The minimum voltage is +5V.
The actual range of voltage for the 0—5V DC Signal output is from approximately 0.5V (at no load)
3.
to 4.5V at full load. The relationship between the load and voltage is on a calibration chart provided
with the sensor and DQ-1000A.
