The 0.016 μs instruction speed and 150K-step memory suit fast conveyor, picker, and reject logic on compact packaging machines.
Maintains deterministic control for many interlocked stations without overloading PLC scan capacity.
Up to 40 connectable units and 3 expansion racks support distributed I/O and mixed special-function modules in a single machine cell.
Reduces controller count while scaling I/O and function blocks across several machine sections.
Panel-mount construction, 0 to 55 °C operation, and IEC shock/vibration compliance fit enclosed industrial cabinets on factory floors.
Provides reliable control in vibrating electrical panels with moderate thermal stress and electrical noise.
