Analog amplifier

Short description
This special function amplifies the value of an analog input and outputs the result at an analog
output.
Symbol in
IDEC SmartRelay
AI1...AI8: 0 V to 10 V corresponds with 0 to 1000 (internal value).
Gain and offset parameters
Please note the information on gain and offset parameters in topic Calculating the gain and
offset of analog values (Page 126).
Parameter p (number of decimals)
Applies only to the A
Functional description
The function fetches the analog signal of input Ax.
This value is multiplied by the value of the A (gain) parameter, and parameter B (offset) is
then added to the product: (Ax gain)
The actual value Ax is output at A .
