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 two level switch (HAND, AUTO) on the front. The switch position is confirmed via the two external control contacts B1 and B2.
Switch position HAND (manual mode)The control variable can be set with the potentiometer on the front. The output signal 0 to 20 mA is available at contact Y. The current flow at input YR is not interrupted.
Switch position AUTO. The input current (YR) is transmitted to the control variable output Y with a tolerance of ±5 % (full scale value).
