Physical Layout and Connection Points

The Fuji FTK500A-C10 weighs 0.31 kilograms for easy panel mounting. Its 115 mm width fits compact control cabinets efficiently. Two independent counter channels accept different input signal types. An 18‑pin spring clamp terminal block provides all field connections. Each channel includes two LED indicators for input activity. A 220 µF capacitor filters supply voltage variations.

Counting Characteristics and Performance

Each channel accepts frequencies up to 5 kilohertz maximum. The module supports quadrature encoders with x1 or x2 multiplication. Therefore, you can capture precise position data from linear scales. The 24‑bit counter holds over 16 million pulses. Consequently, this unit handles long production runs without overflowing. Each channel includes a programmable preset value and comparator output.

Installation and Wiring Guidelines

Mount the Fuji FTK500A-C10 on a DIN rail or using M4 screws. First, disconnect system power completely before wiring. Then select the input mode via configuration software. Wire 24V sensors using standard optocoupler protection. Wire 5V differential signals directly for higher noise immunity. Connect the comparator outputs to PLC inputs for event triggering. After wiring, apply power and set the counter mode. Finally, test with a known pulse generator.

System Integration and Application Notes

This pulse counter works with FTK series controllers and PLC systems. Typical applications include bottle counting on packaging lines. The unit also suits flow meter totalization and cut‑to‑length control. For quadrature encoders, use the x2 mode for better resolution. The comparator output can trigger diverters or alarms at preset counts.
