Analog Control Input 

 

 

The  analog  control  input  allows  controlling  the  NGPS  unit  almost  as  an 

“amplifier”. This input is labelled as “AN CTRL”. 
 
 

This  input  accepts  signals  ranging  from  0V to  +10V  and generates an output 

which  is  proportional  to  the  input  signal:  zero  output  for  a  0V  input  and  Full-Scale 
output for a +10V input. An example of the relation between the analog input signal 
and the output (can be either current or voltage, depending on the Regulation mode, see 

Section 1.3.1

) is shown in 

Figure 10
