Analog adder/ subtracters
The SOM.xRC can be used to add up several analog or digital signals from any source (fume hoods or various devices in operation) to control any control device that accepts a 0-10V such as frequency inverter or exhaust fan
Thus you get an air flow in introduction or extraction proportional to the number of systems in service. A multiplier coefficient can also be added to each input by adjusting the potentiometers.
