Wiring Analog IO
You can wire your existing analog sensors to your IG to capture important data on your assets and operations. Whether your analog sensors output a 4-20mA or 0-10V signal, wiring to the IG21 will be the same. However, the exact wiring of the device depends on the number of wires needed. The following 3 images should be used as a model for your 2, 3, or 4-wire analog device.
