SIMATIC S7-300, Analog module SM 334, potential-bound AE2 AA, 1x 20-pin, pulling and plugging with active backplane bus possible. SIMATIC ET 200M is a modular and universally applicable peripheral system for the control cabinet in IP20, which can be used both as central peripheral equipment for an S7-300 and in decentralized configurations with a PROFINET or PROFIBUS ET200M interface module. Up to 12 I/O modules can be connected per station. The standardized design of all modules significantly simplifies logistics and spare parts management. ET 200M is suitable for both standard and safety-related applications. As peripheral modules interfacing with the process, up to 12 high-channel signals can be utilized, such as 64 digital inputs and function modules, as well as communication processors of the S7-300. Thus, the ET 200M also supports modules with extended payload data, such as HART modules with HART secondary variables. For easy wiring, the ET 200M offers Fast Connect, a stripping-free quick connection technology, in addition to conventional connection techniques.
