SIMATIC S7-300, Analog Input SM 331, isolated, AE, version 91214 Bit, UThermocouple Resistance, Alarm, Diagnostics, 1x 20-pin pull-out connector with active backplane bus. SIMATIC ET 200M is a modular and universally applicable peripheral system for control cabinets in IP20, which can be used both as central peripheral for an S7-300 and in a decentralized setup with a PROFINET or PROFIBUS ET 200M interface module. Up to 12 I/O modules can be plugged into each station. The standardized design of all modules significantly simplifies logistics and spare parts management. ET 200M is suitable for both standard and safety-oriented applications. As peripheral components of the interface to the process, up to 12 high-channel signals, such as 64 digital inputs and function modules, as well as communication processors of the S7-300 can be used. 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, in addition to conventional connection techniques, the strip-free quick connection technology Fast Connect.
