As the proportion of renewable energy sources increases, decentralized suppliers and substations must be consistently monitored. This data must be archived, analyzed and transmitted securely. WAGO's automation systems provide the solution: They are compact, support many interfaces and fieldbus protocols and offer a high level of availability – even in bitter cold or high heat. Thanks to the intrinsically safe Ex i modules for the modular WAGO-I/O-SYSTEM, usage in hazardous areas, like biogas plants, is no problem.
