The ComExflex potentiometer 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). A junction box is available as a safe and convenient means of installing the potentiometer in a control panel.
The conductors are connected by means of terminals on the back of the module which have an increased safety level. The easy installation of the potentiometer actuating element without the need for tools,ensures conformance to the high IP degree of protection.
Note for installation and revision work
For rated voltage:
– ≤ AC 50 V/≤ DC 120 V (Safety extra low voltage in conformance to DIN VDE 0100 T. 410), The potentiometer drive shaft can be operated without an actuator.
– ≥ AC 50 V to max. AC/DC 230 V, Potentiometer drive shaft must be operated with an actuator or disconnected from voltage.
