Overview
The AI-1000-CV Analog Load Cell Interface is used to capture low level
mV/V signals from a resistive bridge type load cell and convert it into a high
level 0-5 V DC voltage output and/or a 4-20 mA current output compatible
with PLCs and DAQs. It can be used with any resistive load cell. It is similar
to the AI-1000 product which only offers the voltage output. This interface
offers BOTH voltage and current output options.
Features
Compatible with all resistive bridge type load cells with mV/V output
§
Powered by 24V DC power supply (provided by user)
§
Input power to load cell can be set (suggested value is 9V)
§
Tunable for easy calibration of your load cell
§
Grommets to protect inlet and outlet
§
Lid with O-Ring to protect enclosure from the elements
§
Two mounting tabs with through holes to fasten unit into your assembly
§
One AI-1000-CV needed per load cell
§
Load Cell must be calibrated with AI-1000-CV prior to use
§
Product Dimensions
4.5 in x 2.7 in x 1.6 in

User Guide Operation Connecting Load Cell to AI-1000 CV Interface 1. Strip any 4-wire cable on both sides and Tin each wire as we will use this wire for the output. It is useful to solder one side of the wire so it is easier to connect the ground cables later 2. - Page 3 User Guide 3. Connect the wires as show in the image below Note the Load Cell connection is almost always as shown except in special cases such as RRP1. In such a case please refer to the loadcell wiring for the correct colors. 4.
- Page 4 User Guide Measuring Current and Voltage from the Interface 1. Use the power supply to provide 24 Volts exactly 2. Connect the red output from the power supply to the red wire on the output cable, connect the black output to the soldered black wires on the output cable 3.
- Page 5 (4.5 V) or max current (20 mA) when full load is applied Adjust the RV and RVS or the RI and RI iteratively until the output meets your target outputs Once calibrated you MUST use the same AI-1000-CV with the same load cell to ensure the accuracy of the signal. loadstarsensors.com...
- Page 6 To avoid damaging the potentiometers, please be gentle with the potentiometers (“Pots”) turns and don’t overdo it. If changing the Pots does not change the output voltage as expected, then make sure to check your load cell independently of the AI-1000-CV and then try again. loadstarsensors.com...
