What is the difference between the KMA-E08 and KMA-R-E08?
R stands for "reverse voltage protected", the KMA-R-E08 is protected against external voltage at the output (e.g. by another KMA).
The analog encoder is used as encoder for manual control variable definition, e.g. mixing valves, valve positions, temperature values, etc. The module can be operated in two modes, which can be commuted by means of integrated two-level switches (HAND, AUTO). The switch position is signalized by external control contact terminals S1 and S2. Switch position HAND. The control variable can be set on the potentiometer at the front. The output signal 0 to 10 V (external voltage protection) is available on the Y terminal. Switch position AUTO. The control variable is looped through over the YR terminal to the Y output without change.
