6AG1321-7RD00-4AB0

The SIPLUS S7-300 SM 321 4DI NAMUR, derived from the 6ES7321-7RD00-0AB0 model, features conformal coating for enhanced durability and is designed for operation in a temperature range of 0 to +60 °C. This digital input module is specifically configured for hazardous areas, offering four isolated digital input channels with a voltage rating of 24 V DC. It supports NAMUR/DIN 19234 standards for signals from the hazardous area, making it suitable for applications with potentially explosive atmospheres. The module is diagnostics-capable and has been tested by PTB (Physikalisch-Technische Bundesanstalt), ensuring compliance with relevant safety standards and regulations. The conformal coating further contributes to the module's resistance to environmental factors, making it a robust solution for challenging industrial environments within a Siemens S7-300 control system.
