Control interfaces
 Programmable analog inputs
The control unit has two programmable analog inputs. Analog inputs can be
used for PID purpose or to read external sensor values. With analog inputs,
speed of the motor cannot be changed as motor speed control is always by
internal MPPT logic of ACQ80. For more information, see section
MPPT control
program

 Programmable analog outputs
The control unit has two current (0…20 mA) analog outputs. Analog output 1
can be set as a voltage (0/2…10 V) or current (0/4…20 mA) output with
parameters. Analog output 2 always uses current. Each output can be filtered,
inverted and scaled.
