The analog input signal level is the combined input signals from the analog voltage input
(AVI) (0 - 10 V) and analog current input (ACI) (4 - 20 mA). The voltage corresponding to
the analog current input (4 - 20 mA) and analog input signal level is defined as follows:

Voltage corresponding to the
analog input signal level
