The IFM AL2341 is a high-capacity digital input module engineered to deliver efficient, reliable, and standardised signal acquisition in decentralised automation environments. With its 20 digital inputs and IO-Link sensor supply, the AL2341 is tailored to support demanding field applications where extensive sensor connectivity and robust compliance with industrial standards are essential.

The module’s standout feature is its 20 digital inputs, arranged as 10 x 2 PNP inputs. Designed in accordance with IEC 61131-2 Type 2 standards, these inputs guarantee compatibility with a wide range of industrial sensors, ensuring consistent and accurate signal processing. This high input density makes the AL2341 ideal for applications requiring extensive monitoring and data collection, such as machine automation, production lines, and distributed control systems.

Power efficiency is a core part of the AL2341’s design. Operating within an 18…30 V DC supply range, the module adapts easily to standard industrial power systems. Its current consumption ranges from 100 to 1100 mA (US), providing stable performance without overloading the supply. With each port rated for 0.1 A, the AL2341 is optimised for reliable operation with a wide variety of connected input devices, from sensors to switches.

A key benefit of this module is its IO-Link powered sensor supply. By leveraging IO-Link, the AL2341 ensures that connected sensors receive a stable and standardised supply, while also simplifying wiring and reducing system complexity. This not only improves installation efficiency but also supports advanced communication and diagnostic features that IO-Link enables, giving operators greater transparency and control over connected devices.

The AL2341 is designed for durability and safety in industrial environments. With a Protection Class III rating, it complies with safety standards for low-voltage systems, ensuring safe operation for both equipment and personnel. Its robust construction ensures long service life, even under challenging field conditions.

Engineers benefit from the decentralised installation capability of the AL2341. By placing the module directly in the field, close to sensors, it reduces the need for long cabling runs back to a central control cabinet. This not only lowers installation costs but also improves system responsiveness and scalability. Its high input density in a single compact housing makes it particularly attractive for space-constrained installations that demand efficiency.

In real-world applications, the AL2341 is well-suited for industries such as automotive manufacturing, packaging, and process automation, where large numbers of digital signals need to be captured reliably. Its combination of 20 PNP inputs, IO-Link sensor supply, robust power handling, and decentralised field installation design makes it a valuable component for engineers aiming to build scalable, efficient, and future-ready automation systems.

In summary, the IFM AL2341 offers a comprehensive solution for high-density digital input requirements. With its 20 PNP Type 2 inputs, IO-Link integration, robust power efficiency, and Protection Class III design, it ensures dependable performance, simplified wiring, and compatibility across a broad range of automation applications.
