Han-Modular Surge Protection Modules from Harting Canada for Instrumental and Control (I&C) signals usually requires separate, external solutions that add to material and labour costs, the company says. The new surge protection (SP) modules for the user-configurable Han-Modular lineup, when used correctly, 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, it adds.
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 24 Vdc and up to 0.5 A.
The protection level is approximately 50 V depending on the type.
