Rievtech x-Messenger Series - Analog Amplifier

273
6.5.23 Analog amplifier
Short description
This SFB amplifies an analog input value and returns it at the analog output.
Connection
Description
Input Ax
Input the analog signal to be
amplified at input Ax.
Use the analog inputs
AI1...AI8, the analog outputs
AQ1 and AQ2.
AI1..AI8: 0 - 10 V corresponds
with 0 - 1000 (internal value).
Parameter
A: Gain
Range of values: ± 10.00
B: Zero offset
Range of values: ± 10000
p: Number of decimals
Range of values: 0, 1, 2, 3
Output AQ
Analog output
Value range for AQ:
-32768...+32767
Parameter p (number of decimals)
Applies only to the display of Ax and Ay values in a message text.
Does not apply to the comparison of On and Off values! (The compare function ignores the decimal point.)
Description of the function
The function reads the value of an analog signal at the analog input Ax.
This value is multiplied by the gain parameter A. Parameter B (offset) is added to the product, i.e.
(Ax ∙gain) + offset = Actual value Ax.
Setting the Par parameter
The gain and offset parameters are used to adapt the sensors to the relevant application.
