PLCs, Power Supplies & Others

This digital input module provides reliable signal capture for compact control applications. It integrates seamlessly into the Fuji Electric NV series programmable controller platform. The unit monitors up to sixteen independent input channels from a single module slot. Users can connect proximity sensors, limit switches, and pushbuttons with consistent performance.

Input Channel Configuration and Electrical Specifications

This module features sixteen digital input channels for versatile field connectivity. Each channel accepts 24 V DC signals from 0 V to 30 V for broad compatibility. The input current per channel measures approximately 3.5 mA at nominal voltage. Each input includes built-in filtering for reliable noise rejection. The channels are electrically isolated from the internal logic bus.

Signal Processing and Response Performance

The NV1X1604-W processes each input signal with programmable delay settings. Users configure the input filter from 0.1 ms to 10 ms for noise immunity. This adjustable filtering accommodates both high-speed counting and contact debouncing. Each channel provides a green LED indicator for real-time status visualization. The module also stores diagnostic data for each input channel. Consequently, operators can identify intermittent sensor faults quickly.

Diagnostic Functions and Fault Detection

This input module includes comprehensive diagnostic capabilities for reliable operation. It detects wire-break conditions on input channels for 24 V DC sensors. The module also identifies input short-circuits and reports them to the CPU. Diagnostic messages appear in the PLC program for immediate operator response. The module performs self-tests during every power-up cycle. This diagnostics suite simplifies troubleshooting and reduces system downtime.

System Integration and Configuration

This module communicates with the NV series CPU through the dedicated backplane bus. It automatically maps inputs to the PLC memory for easy programming. Users configure the module using the Fuji programming software environment. The software provides intuitive tools for filter settings and diagnostics configuration. Configuration data is stored in the CPU for automatic recognition. This plug-and-play design simplifies commissioning and module replacement.

Energy Consumption and Thermal Management

The module draws 30 mA at 5 V DC from the backplane for internal logic. External power requirements come from the field supply via dedicated terminals. Power dissipation remains below 1 W under normal operating conditions. Natural convection cooling maintains safe temperatures across all components. Consequently, the operating range spans 0 °C to 55 °C for standard factory environments. Humidity tolerance reaches 10% to 90% without condensation concerns.

Installation and Space-Efficient Design

This module features a compact 45 mm width for efficient cabinet space utilization. The narrow footprint enables high-density installations in compact control panels. Installers snap the unit onto a standard DIN rail without tools. The module connects to adjacent NV series modules via integrated bus connectors. A removable terminal block simplifies field wiring and maintenance. The housing carries an IP20 rating for protection against solid objects. This robust design suits packaging machinery, conveyor systems, and assembly stations.
