Reliable Input Interface for NP1 PLCs

The Fuji NP1X1610-RI provides 16 digital input channels for the NP1 series programmable controllers. This module accepts 24 V DC signals from limit switches, proximity sensors, and pushbuttons . It draws 7 mA per channel for consistent and reliable signal detection . Consequently, this input module suits conveyor control, packaging lines, and material handling systems.

Input Circuit and Isolation Design

The NP1X1610-RI employs opto-isolation to separate field inputs from the internal bus . This design protects the PLC backplane from voltage spikes and electrical noise . Each input channel includes a built-in low-pass filter for noise rejection . Furthermore, green LED indicators show the ON/OFF status for every channel .

Response Time and Performance Characteristics

The module processes input signals with a response time of 5 milliseconds . It effectively filters contact bounce and transient interference . The Fuji NP1X1610-RI provides diagnostic data through the system registers . Its input impedance matches standard 24 V DC sourcing sensors .

Physical and Mounting Specifications

The module weighs 0.2 kilograms and occupies one standard NP1 slot . It plugs directly into the backplane without additional wiring . The NP1X1610-RI uses a 20-pin connector for field terminations . Its compact design allows high-density I/O configurations .

Electrical and Environmental Parameters

This input module consumes 50 mA from the 24 V DC supply . It operates reliably between 0 and 55 °C ambient temperature . The Fuji NP1X1610-RI stores from -25 to 70 °C during transport . It meets industrial EMC and vibration standards .
