What is the difference between the KMA-F8 and KMA-R-F8?
R stands for "reverse voltage protected", the KMA-R-F8 is protected against external voltage at the output (e.g. by another KMA).
The analog encoder is used for manual control variable settings for example for mixing valves, valve positions, temperature values etc. The module can be controlled in two operating modes that are set by means of the three level switch (ON, OFF, AUTO) on the front. The switch position is confirmed via the two external control contacts B1 and B2. Switch position ON: The control variable can be set with the potentiometer on the front. The output signal 0 to 10 V is available at contact Y. Switch position AUTO: The control variable is transmitted via contact YR without change to the control variable output Y.
