The ComEx potentiometer module is used in almost all hazardous (potentially explosive) areas where machine functions are controlled by means of adjustable voltage distributors. The module can be combined with a potentiometer actuator (scale graduation 0 to 10) and is available in versions with 1 kΩ and 10 kΩ.
