2.4.2 Analog input 2

Analog input 2 is designed as a current input.

It can be used in conjunction with industry standard current loop transducers & sensors. Input impedance is 50Ω. The 0-20mA input is converted internally to a digital raw range of 0-4095.

Note: Applying a voltage source to the current input AI2 may damage the internal 50Ω input resistor and respectively the entire input circuit.
