Fuji NU2F-HC2 High-speed Counter Module

Counting Architecture and Pulse Processing

The Fuji NU2F-HC2 functions as a dedicated high-speed counter module for precision motion and position tracking applications. It accepts incremental encoder signals for accurate counting of position, speed, and distance. This module supports up to 100 kHz input frequency for high-speed pulse processing. It handles both quadrature encoder signals and single-phase pulse inputs efficiently.

This counter module provides two independent counting channels that operate simultaneously without interference. Each channel features programmable count modes including up/down, quadrature, and direction control. Consequently, engineers can deploy this unit in applications requiring precise position feedback and motion control.

Physical Specifications and Interface Connections

The NU2F-HC2 measures 12.0 cm in height, 7.5 cm in width, and 11.5 cm in depth. It weighs approximately 0.29 kg, allowing for straightforward installation in standard Fuji NU Series racks. This module occupies a single slot on the baseplate and connects directly to the backplane bus. The front panel features LED indicators for channel status, power, and count activity monitoring. These visual indicators provide immediate feedback during system startup and troubleshooting.

A removable terminal block accommodates all field wiring connections for the encoder inputs. This terminal block accepts wire sizes ranging from 0.2 to 1.5 mm² (24 to 16 AWG). The module also includes shield connection terminals for minimizing electrical noise interference on high-frequency signals.

Power Consumption and Energy Storage

This high-speed counter module draws 130 mA from the backplane at 5 VDC for internal logic operation. It incorporates energy storage capacitors that maintain count values during brief power interruptions. These capacitors provide approximately 10 milliseconds of hold-up time to preserve accumulated data. The module also retains configuration settings and count values in non-volatile memory without battery backup.

Technical Specifications

System Integration and Motion Control Applications

The NU2F-HC2 integrates seamlessly with Fuji NU Series PLCs and motion control systems. It supports preset and compare functions for triggering events at specific count values. Users can configure counting parameters using Fuji standard programming software for flexible application setup. This high-speed counter module enables precise position tracking for conveyors, packaging machines, cutting equipment, and material handling systems.
