140DDI35310 Schneider Relay Module
140DDI35310 is a digital input module from Schneider Electric's Modicon Quantum series, designed specifically for industrial automation control systems. It features high reliability and modular design, supports multi-channel digital input (usually 16 or 32 channels, depending on the model configuration), and is compatible with dry or wet contacts. The input voltage range is usually DC 24V (specific values need to refer to the data manual), with a response time of less than 1ms. The power supply voltage is DC 24V (± 10%), and the power consumption is usually a few watts. The operating temperature range is 0 ° C to 60 ° C, and the storage temperature range is -40 ° C to 85 ° C. The protection level reaches IP20. It can communicate with Modicon Quantum PLC through the backplane and supports online communication. Diagnostic and troubleshooting functions, easy to maintain, in compliance with International Electrotechnical Commission (IEC) standards and CE Certification is widely used in automation production lines, process control systems, and equipment monitoring scenarios. It is compatible with Modicon Quantum series PLCs and other modules and can be flexibly integrated into various industrial control systems.
