For industrial and building management systems. Analogue value output modules are used as a precautionary measure to replace a specified or faulty analogue value from 0 – 10 V with a manually adjustable value. In the H switch position (manual), an adjustable signal is available at the output on the front knob instead of the value generated in automatic mode. The values of the analogue value specified by the regulation process and the set analogue value are shown by three green LEDs. A non-automatic operational state is indicated by a flashing yellow LED. Typical applications are manual provision of default variables in water mixing valves, regulation of fresh air to recirculating air ratios, industrial analogue regulation processes and so on.
