For industrial and building management systems. Analog value output modules are used as a precaution to replace a preset or faulty analog value of 0 - 10 V with a manually adjustable value. In switch position H (manual), a signal adjustable at the front rotary knob is available at the output instead of the value generated in automatic mode. The level of the analog value given by the control process as well as the set analog value is visiualized by three green LEDs. The operating state non-auto is indicated by a flashing yellow LED. Typical application is the manual provision of a manipulated variable preset in water mixing valves, control of the ratio of fresh air to recirculated air, analog control processes in industry, etc.
