For the first time, the base unit PNOZ m B1 contains no inputs or outputs: expansion modules are used to adapt the system to the application. Two integrated Ethernet interfaces save costs, as there is no need to connect an ETH expansion module. The number of expansion modules that can be connected on the right-hand side has been increased to eight on the base unit. Short downtimes and high plant availability are guaranteed by connection to common fieldbus systems via the respective expansion modules.
