SCHNEIDER 140DAI54300 Discrete Input Module

• Number of Input Points: It has 32 discrete input channels, which can be connected to multiple external devices (such as buttons, limit switches, sensors, etc.) simultaneously, meeting the signal collection requirements of medium and large-scale automation projects.​

• Input Type: It supports 24V DC input, which is in line with industrial standard voltage. It can be adapted to common industrial sensors and switch devices, ensuring signal compatibility.​

• Isolation Characteristics: Each input channel adopts optoelectronic isolation technology, with an isolation voltage of up to 500V AC. It effectively isolates external electrical interference, preventing voltage fluctuations, electromagnetic interference, etc. from affecting the module and control system, and ensuring the safe operation of the system.​

• Fast Response: The signal response time is extremely short. It can capture the changes of input signals within milliseconds and transmit the signals to the control system in a timely manner, which is suitable for scenarios with high real-time requirements, such as automated production lines.​

• Diagnostic Function: It has a built-in self-diagnosis mechanism, which can monitor the status of each input channel in real-time. When faults such as short circuits, open circuits, and overvoltage occur, the fault information is intuitively displayed through the LED indicator on the module. At the same time, the diagnostic data is fed back to the control system, facilitating maintenance personnel to quickly locate and troubleshoot faults and reducing equipment downtime.​

• Communication Protocol: It is highly compatible with the SCHNEIDER Quantum series PLCs. It realizes high-speed data communication with the PLC through the Quantum system bus, ensuring that the input signals are accurately and timely transmitted to the control core for efficient automated control.​

• Installation Method: It adopts a standard 35mm DIN rail installation, and the installation process is simple and quick. It can be easily integrated into various industrial control cabinets. The module has a compact design, saving space in the control cabinet and facilitating system expansion and maintenance.​

• Operating Temperature Range: It can operate stably in an ambient temperature range of 0°C to 60°C, adapting to most industrial production environments. The storage temperature range is - 25°C to 70°C, ensuring that the product is not affected by extreme temperatures during transportation and storage.​

• Protection Level: The protection level reaches IP20, providing basic dust-proof capability. Under complex industrial conditions such as vibrations and electromagnetic interference, it can still maintain stable performance and ensure reliable operation.​
