8.2.5.3 Analog input - ANA1 (0 - 10V) on INPUT 2
As an option, it is possible to have an analog input instead of the opto-coupled input I2.
This analog input allows to do a voltage measure (contact us).

The integrator has the responsibility to protect the input from electric disturbances and to
respect the values of the functioning parameters.
