Note
Different cable glands
A blue and a gray cable gland are provided to distinguish between explosion-proof and not
explosion-proof devices.
• Use the blue cable gland for explosion-proof devices in "intrinsically safe" protection type.
Function
You will require the EMC filter module if you use an external position sensor on the
positioner, e.g. a potentiometer or a non-contacting position sensor. The EMC filter module
forms the interface between external position sensors and the basic electronics of the
positioner. This module protects the positioner from electromagnetic effects.
