Appoldt Analog value transmitter

This setpoint transmitter controls valves, mixing dampers, or temperature values in emergency situations by outputting an analog signal of 0 - 10 V. The module is operated in two modes (Manual/Automatic) via a 2-position switch. The state of the potential-free contact S1/S2 indicates whether the module is in Manual or Automatic mode. The analog value transmitter is used, among other applications, in building automation. Switch position Manual: The setpoint is adjusted using the potentiometer on the front. The signal is present between terminals Y and A2. Switch position Automatic: The setpoint is directly connected from terminal Y to terminal Yr without any changes.
