The analog value transmitter serves as a control variable transmitter for manual control variable specification, e.g. mixing flaps, valve positions, temperature values, etc. The module can be controlled by two operating modes, which can be switched using an integrated two-stage switch (MANUAL, AUTO). The switch position is reported back via the external control contact terminals S1 and S2. Switch position MANUAL: The control variable can be set using the potentiometer on the front. The output signal 0 ... 10 V is available at terminal Y. Switch position AUTO: The control variable is passed through to the control variable output Y without change via terminal YR., Setpoint transmitter, manual control level with feedback, LED brightness proportional to the control variable
