The IFM AL1202 is a high-performance I/O module designed for field applications, offering a robust and scalable solution for decentralised automation. With its dual power supply system, integrated daisy-chain functionality, and compact field-ready design, the AL1202 simplifies installation, enhances flexibility, and ensures reliable operation even in demanding industrial environments.

One of the key advantages of the AL1202 is its integrated daisy-chain function, which extends to both the voltage supply and the fieldbus interface. This feature enables engineers to connect multiple modules in series, reducing cabling complexity and installation time while supporting scalable system designs. Whether in machine building, production lines, or distributed plant control, the daisy-chain capability ensures seamless integration and straightforward system expansion.

The module operates on a 20…30 V DC supply (US) in accordance with SELV/PELV safety standards, ensuring safe operation for both personnel and equipment. With a current consumption range of 300…3900 mA, it provides sufficient energy to manage connected devices without compromising network stability. To further strengthen its power handling, the AL1202 includes an additional auxiliary supply (UA) of 20…30 V DC, ensuring outputs and field devices have a stable, dedicated power source. This dual-supply design not only balances system loads but also provides greater resilience and reliability in power distribution.

Capable of handling a maximum total current load of 3.6 A, the AL1202 is well-suited for supporting multiple sensors, actuators, and other devices within decentralised automation networks. Its design ensures consistent and safe operation even when managing high-current loads, making it a dependable choice for applications with intensive power demands.

Safety and durability are central to the AL1202’s construction. With a Protection Class III rating, the module provides electrical safety and resilience in harsh industrial environments. Its short-circuit proof design ensures system protection even under fault conditions, minimising downtime and safeguarding both the module and the wider automation system.

By enabling field-level installation, the AL1202 reduces the need for long cable runs back to central control cabinets. This decentralised approach cuts installation costs, enhances system responsiveness, and supports modular plant layouts where flexibility and scalability are essential. Engineers benefit from faster commissioning, easier maintenance, and the ability to expand systems with minimal disruption.

In practical terms, the AL1202 is ideal for a wide range of industrial applications, including process automation, machine building, and distributed control systems. Its combination of daisy-chain networking, dual voltage supply, and robust power handling makes it a versatile and future-proof module that meets the demands of modern automation.

In summary, the IFM AL1202 delivers a complete solution for field I/O requirements. With its daisy-chain functionality, dual supply design, 3.6 A power capacity, and Protection Class III safety rating, it ensures efficiency, reliability, and scalability in decentralised automation systems.
