Polyamide-based (PA) technopolymer, grey colour.
Safety control unit for category 3 and 4.
Contact blocks in the standard execution:
CN-SFT can be used in conjunction with the following Elesa products:
The CN-SFT safety control unit is able to control the status of two contacts (safety Reed magnetic sensors, emergency buttons, mechanical safety switches, safety interlocks for mobile guards): the output is activated by pressing and releasing the START button (reset) only if the NO contact is open and the NC contact is closed (NO-NC version) or only if the two NC contacts are closed (NC-NC version).
The switching of even just one input contact results in a safe situation, placing the safe outputs in an open state and preventing them from closing again, even after a new switching of the contact and pressing the START (reset) button.
