SIPLUS ET 200M IM153-4 PN IO is based on 6ES7153-4AA01-0XB0 with Conformal Coating, operating from -25 to +70°C, for a maximum of 12 S7-300 modules. Enhanced features include isochronous real-time communication Class 1 and 2, module replacement without a PG, operation without an MMC, and maintenance support for new IO modules. 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 a decentralized setup with a PROFINET or PROFIBUS ET 200M interface module. Up to 12 IO modules can be plugged in per station. The standardized design of all modules significantly simplifies logistics and spare parts management. If your decentralized peripherals are unprotected or in small control boxes, SIPLUS extreme ensures reliable operation in the field. Whether it’s temperature extension, protection against moisture and condensation, or exposure to mechanically, biologically, and chemically active substances, with SIPLUS extreme you are safe even in harsh environmental conditions.
