Digital Sensors, Sinking (NPN) Inputs
Neither the inputs nor the outputs on the DX80 devices are isolated. Under certain operating conditions, externally powered sensors may need
to have ground in common with the DX80 device to which they are connected. The power sources do not have to be the same.
