Turck FDNL-S1600-T DeviceNet Communication Hub

Description:

The TURCK FDNL-S1600-T Device-Net Hub is used in industrial automation systems as a distributed input station for Device-Net fieldbus networks. Commonly installed in machine-mounted control points, packaging systems, conveyor lines, automotive production equipment, and factory automation systems requiring decentralized digital input collection with diagnostics. Maintenance teams, OEMs, and system integrators use this module for field I/O expansion, network integration, and replacement of legacy Device-Net input stations.

Applications:

The TURCK FDNL-S1600-T is used in Device-Net-based automation environments where multiple digital sensor inputs must be collected close to the machine or process. Typical applications include automotive assembly lines, packaging machinery, material handling systems, conveyor automation, and industrial production cells requiring local input aggregation, reduced cabinet wiring, and real-time communication with PLC systems.
