RC protection circuit for contactors DILM17..38 DILM32-XSPR48 281202

The RC protection circuit for DILM17..38 contactors is an extremely important element in every control system where contactors are used. Its main function is to protect the system against overvoltages and electromagnetic interference that may occur during the connection or disconnection of inductive circuits such as contactor coils. This element effectively suppresses sparking on auxiliary contacts and limits electrical noise, which significantly improves the reliability of the entire installation.

The use of the RC circuit also allows for the contactor itself to be used longer by reducing the mechanical and electrical wear of its components. Furthermore, since the module operates in a wide range of AC control voltage from 240 to 500 Hz at a frequency of 50 Hz, it can be used in
