Non-stop transmission via fieldbus 

Ifm electronic introduces Ethernet modules for field applications, the AL4xxx series. These decentralised DI modules act as a vital link between binary sensors and the fieldbus, enabling smooth transmission of binary switching signals via the fieldbus without additional transmission systems.

The key features and benefits of the AL4 series include direct transmission of binary signals with fieldbus topology for improved efficiency, a robust design for durability in harsh environments. The ecolink technology guarantees reliable, permanently ingress-resistant M12 connections of the connection cables. The perfect addition to ifm IO-Link family.

The materials and production methods utilised in these modules mirror the renowned quality of ifm’s jumper cables from the acclaimed EVC and EVF product series, exemplifying a commitment to excellence and durability.

Technical advancements include a voltage supply system with an A-coded M12 connector and an L-coded M12 connector with daisy chain functionality for efficient power distribution. Furthermore, there is an integrated counter function suitable for high-frequency counter applications, ensuring accurate counting regardless of PLC cycle times.

The integration of Ethernet modules into ifm’s IO-Link master family represents a significant step towards comprehensive automation solutions that prioritise seamless connectivity and operational excellence.
