The AIM1 offers a 24 VDC power output to allow a loop powered device to be connected directly to the AIM1. When the loop device is functioning, measure the voltage from I3 (-) terminal to I2 (+) terminal. The 4-20 mA signal generates a proportional 1-5 VDC across these terminals. This is an easy way to confirm proper connection and operation using Ohm's law. The AIM1 4-20 mA output signal will be completely isolated from the 4-20 mA loop input signal. The output signal will be limited to a maximum of 20 mA. The AIM1 shares the same common on the power supply and input signal.
