Physical Layout and Connection Details
The Fuji NP1X1610 weighs only 0.28 kilograms for lightweight mounting. Its 68 mm width occupies a single slot on the base board. Sixteen input channels appear on a 20‑pin spring clamp terminal block. Each channel includes a red status LED for visual confirmation. A 220 µF capacitor filters supply voltage fluctuations effectively. The module uses optocouplers to isolate every input from the backplane.
Input Characteristics and Signal Processing
Each channel accepts voltages from 10V up to 30V DC. The module recognizes any signal above 15V as logic high. Similarly, signals below 5V register as logic low. The response time reaches just 1.5 milliseconds for both transitions. Therefore, this unit captures standard sensor signals without missing events. The 7 mA input current suits most proximity switches and push buttons.
Installation and Wiring Guidelines
Mount the Fuji NP1X1610 into any NP1 series base slot. First, disconnect system power completely before handling. Then connect each sensor wire to the designated terminal. Use a common 24V source for all sink/source configurations. The module accepts both NPN and PNP sensor types. After wiring, apply power and verify each LED lights correctly. Finally, test every channel with a signal generator.
System Integration and Application Notes
This input module works with all NP1 series CPUs and power supplies. It occupies one slot regardless of the 16 channel count. Typical applications include limit switch monitoring and push button panels. The unit also suits photoelectric sensor arrays on packaging lines. For expanding beyond 16 points, add a second module. The compact design allows dense cabinet layouts.
