ProMinent DULCOMETER diaLog DACb - 11.11 Remote setpoint via a 0;4... 20 mA analogue signal

Multiplicative interference variable
The multiplicative interference variable can influence the control variable of the setpoint controller
over the entire control range proportionately to the interference variable. This corresponds to a pro‐
portionality factor of 0.00 = 0% and 1.00 = 100 %, including all intermediate values.

Availability of the remote setpoint
The menu [Remote setpoint (mA)] is only available with the 1-channel control of the con‐
troller.
The function [Remote setpoint] makes it possible for you to change the setpoint within a to be speci‐
fied range for all measured variables of the controller channel 1 using an external 0/4 ... 20 mA ana‐
logue signal. The analogue signal can originate as an active signal from a PLC Programmable Logic
Controller or also be specified using a 1 kOhm precision potentiometer.
