Schneider Electric 140DSI35300 Low Voltage DC Discrete Input Module

The Schneider Electric 140DSI35300 is a versatile, high-capacity discrete input module designed for integration into industrial automation systems requiring accurate and reliable low-voltage DC input processing. This module, a part of Schneider's Modicon Quantum I/O family, is built for performance in high-demand environments, offering advanced input handling with multiple channels and robust protective features. The 140DSI35300 comes with a 2-year MRO Electric and Supply warranty, guaranteeing quality and reliability for extended use in complex systems.

Module Overview and Design

Built in a standard module format, the 140DSI35300 features 32 discrete inputs across four groups. Each input group operates on a 24 V DC discrete input voltage, with the logic input configuration set to positive (sink), a setup suitable for applications requiring stable DC inputs. With its high input count and transparent organization, the 140DSI35300 is a solid choice for complex systems needing multiple input channels within a compact design. This module's addressing requirement is four input words, which simplifies data communication and control within larger automation systems.

Voltage and Current Specifications

The 140DSI35300 is engineered to operate within specific voltage and current parameters that ensure reliable input processing. The input voltage is set at 24 V DC, with operational voltage limits ranging between 20 and 30 V. The module guarantees input voltage states, with a state 1 (ON) voltage threshold of 11 V or higher and a state 0 (OFF) voltage threshold of 5 V or lower. Current levels are also strictly defined, with a minimum current of 2.5 mA required for state one and a maximum of 1.2 mA for state 0, ensuring accurate input status detection and processing.

Performance and Response Time

Performance is critical with the 140DSI35300, and the module features a fast response time to ensure timely input processing. The module's state 0 to state one transition time is approximately 2.2 milliseconds, while the state 1 to state 0 transitions is around 3.3 milliseconds. This rapid response capability makes the 140DSI35300 an excellent choice for time-sensitive applications requiring real-time input detection.

Protective Features and Isolation

Schneider has integrated several protective features to enhance the module's durability and reliability. The 140DSI35300 can handle an absolute maximum input of up to 45 V DC for short durations (up to 10 ms), protecting against temporary surges. Additionally, the module provides robust isolation to prevent signal interference; isolation between each input group and the bus is rated at 1780 Vrms for one minute, and isolation between groups is set at 500 Vrms for one minute. These isolation levels minimize the risk of electrical interference and protect against short circuits, ensuring stable performance across input channels.

Local Signaling and Monitoring

The 140DSI35300 includes convenient local signaling to enhance monitoring and diagnostic capabilities. It features a green LED to indicate active bus communication, a red LED for external fault detection, and 32 green LEDs displaying the status of each input, making it easy to monitor the module's operational state. The module also includes a built-in broken wire detection feature, adding a layer of security by alerting users to potential connectivity issues.

Power Requirements and Certification

Designed for efficient power use, the 140DSI35300 operates with a bus current requirement of 250 mA, making it an energy-efficient choice for systems with multiple input modules. It is CE-marked, signifying compliance with global safety and performance standards, ensuring its suitability for various industrial applications.
