SIMATIC S7, digital input SM 326, 8 DI DC 24V, NAMUR, fail-safe NAMUR input for SIMATIC S7 F systems, up to category 4 (EN 954-1) / SIL3 (IEC61508) /PLE (ISO13849), 1x 40-pin The SIMATIC ET 200M is a modular and universally applicable I/O system for the control cabinet in IP20, which can be used both as a central I/O on an S7-300, and in a decentralized configuration on a PROFINET or PROFIBUS ET 200M interface module. Up to 12 IO modules can be plugged into each station. The standardized structure of all modules significantly simplifies logistics and spare parts management. The ET 200M can be used for both standard and safety-related applications. Up to 12 high-channel signal (e.g. 64 digital inputs) and function modules as well as communication processors of the S7-300 can be used as peripheral modules (the interface to the process). The ET 200M also supports modules with extended user data, such as HART modules with HART auxiliary variables. For easy wiring, the ET 200M offers you Fast Connect, a quick connection technology that does not require stripping, in addition to conventional connection technologies.
