The Applications

1. High-Speed Packaging and Cartoning Lines

In automated packaging systems, the UR20-16DO-P is widely applied to control solenoid valves, pneumatic cylinders, and signal lamps that operate at high cycle rates. Its fast switching performance supports accurate timing for sealing jaws, cutters, and label applicators, even on lines running continuously at high speed. The high number of outputs in a slim module reduces cabinet space and wiring effort. Built-in output protection limits the impact of wiring faults during maintenance, allowing machines to recover quickly and resume production with minimal operator intervention.

2. Conveyor and Intralogistics Automation

For conveyor systems and warehouse automation, this module is used to drive relays, diverters, and visual indicators distributed along long material flow paths. The ability to handle inductive DC loads ensures stable operation of contactors and signaling devices. Electrical isolation improves reliability in environments with multiple motors and frequent start-stop cycles. High total output capacity allows several conveyor zones to operate simultaneously. System designers benefit from a compact I/O layout that can be expanded easily as material handling lines grow or layouts change.

3. Modular Process Skids and Utility Systems

In modular process skids for water treatment, chemical dosing, or utility control, the UR20-16DO-P provides dependable switching of valves, pumps, and alarm devices. Decentralized installation close to field equipment shortens cable runs and simplifies commissioning. Automatic protection against short circuits is especially valuable during startup and modification phases, when wiring changes are common. Consistent DC output performance helps ensure predictable valve actuation, while clear status indication supports faster fault localization and more efficient maintenance planning.

4. Machine Tool and Assembly Line Control

Within machine tools and automated assembly stations, the module is used to operate clamps, ejectors, cooling valves, and stack lights that require precise, repeatable switching. Fast response times help maintain synchronization between motion control and auxiliary functions. The push-in wiring concept reduces assembly and service time during machine build. Designed for frequent switching cycles, the outputs support long service life. This allows machine builders to deliver compact, reliable equipment that meets demanding production targets and quality standards.
