Important Points in the Wiring Setup:
- 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.
