Description
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.
All contacts of the ComEx potentiometer module are self-cleaning, and the NC contacts feature positive opening. The connecting cable is connected to the ComEx potentiometer module via screw terminals. The ComEx potentiometer module offer the option of simple and fast mounting on a rail- or a panel mounted installation per direct mounting to the ComEx actuator. The ComEx potentiometer modules are developed and certified for globally market.
