HARTING's new Han-Modular Surge Protection Modules make it possible to move surge protection into its most widely used industrial connector series, a space-saving idea that simplifies wiring arrangements. Proper surge protection for Instrumental and Control (I&C) signals usually requires separate, external solutions that add to material and labor costs. When used correctly, the new surge protection (SP) modules will reduce the number of operating faults, increase the service life of the production line, and ultimately increase production uptime for better plant operating performance. There are two types of SP module: a two-channel version for differential signals and four-channel type for signals with common reference potential. Each can transmit nominal 24Vdc and up to 0.5A. The protection level is approximately 50V depending on the type. Transient energy, which can disturb signal circuits and destroy electronic devices, is discharged to the ground via an appropriate spring element and the grounded Han-Modular Hinged Frame. This ensures interference-free transmission of the signal.
