Fuji NC1S-1 NC1H-PL1 Programmable Controller

Compact Control Solution for Demanding Applications

This programmable controller combines reliable processing with flexible I/O options. The Fuji NC1S-1 serves as the base CPU unit for small to medium automation tasks. The NC1H-PL1 adds high-speed counter functions for precision motion control. Together, these modules provide a complete control solution for machine builders. Consequently, this system handles both logic and positioning applications efficiently.

Processing Power & Functional Capabilities

The Fuji NC1S-1 executes ladder logic programs with consistent scan times. It supports up to 256 digital I/O points for typical machine control needs. The NC1H-PL1 adds two high-speed counter channels for encoder feedback. Each counter channel accepts 50 kHz input signals from incremental encoders. Therefore, this combination suits packaging machines, cut-to-length systems, and indexing tables.

Installation & System Integration

You mount the Fuji NC1S-1 on a DIN rail as your main controller. Connect the NC1H-PL1 to the expansion port using a ribbon cable. The system automatically recognizes the high-speed counter module after power-up. You then wire encoders to the dedicated differential input terminals. Your ladder program reads counter values directly from special memory registers.

Operational Advantages & Typical Applications

The NC1H-PL1 handles encoder counting without burdening the main CPU. This approach maintains fast scan times even during high-speed counting. You can preset counter values, set compare outputs, and reset channels programmatically. The combination provides precise position tracking for flying cutters and shears. Therefore, this Fuji controller pair offers reliable performance for synchronized motion applications.
