The 1st AIM1 interface powers the sensor from its 24 VDC terminal I1. The 4-20 mA loop powered sensor signal is fed back into terminal I2 and then into the 2nd AIM1 interface. The 1st AIM1 should be jumper shunt selected for current on both the input and output. A jumper wire is necessary between both interfaces on terminal I3. The 2nd AIM1 should be jumper shunt selected for a 0-5 VDC input signal. The 4-20 mA signal is converted to 1-5 VDC from the 1st AIM1 input impedance of 249 ohms. Both AIM1 interfaces will output a limited 4-20 mA signal, never going above 20 mA or below 4 mA. AIM1's on-board optical isolation feature allows isolated output signals despite shared common.

Many factors influence choosing the proper duct averaging sensor for your application. For example; duct size, air stratification, temperature range, the use of UV lights and more must be considered when making your choice. Watch as ACI’s Tech Support Engineer, Kurt Spackman, addresses choosing the best averaging sensor for you application, mounting best practices, and the benefits of using an averaging sensor versus a single point duct sensor in ACI's Tech Tips Video #4, Choosing and Properly Installing Duct Temperature Averaging Sensors.

The ARM (Analog Rescaling Module) can receive a “negative” signal and convert it to a “positive” signal.
The illustration shows an ARM interface receiving a 0 to (-10) VDC “negative” signal and converting to a 0 to 10 VDC “positive” signal, so a controller can interpret properly. It is very important to use an “Isolated” or non-shared 24 VAC transformer in this application. Note: The input signal leads are swapped.
If the application requires total signal isolation to be used, then we recommend an AIM1 interface
If the application requires total signal isolation, re-scaling, or output signal limiting; then we recommend the AIM2 interface.

Need to boost the current of your control signal? Not a problem!
This interface will do it!
This ARM (Analog Rescaling Module) will convert a 1 mA powered signal into as much as 25 mA @ 10 VDC. Boosts the signal while drawing only 10 microamps. Low cost, field adjustable, normal or reverse acting.
