FUJI NP1X3206-A High-speed digital input module

The NP1X3206-A is a 32-point high-speed digital input module in Fuji Electric's MICREX-SX series, specifically designed for industrial automation scenarios.

It can be installed on this series of substrates and accurately capture high-speed pulse signals to complete signal transmission, making it suitable for control scenarios that require high-frequency signal acquisition

Core technical parameters

Input basic specifications

It features 32 input channels and adopts a 1-loop structure design, compatible with a rated voltage of DC24V.

The input form is source input, and the rated current is 4mA when operating at DC24V. The pulse capture capabilities of different ports vary.

Ports 1-8 can capture pulse signals as small as 20μs, while ports 9-32 can capture pulse signals as small as 100μs. It also features a pulse counter input function, capable of accommodating up to 20kHz input signals and supporting 4-channel (2-phase) selection.

Electrical and environmental parameters

When fully activated, the internal current consumption is below 50mA at DC24V. The insulation endurance between the external terminal as a whole and the ground reaches AC1500V/1 minute.

When measured with a DC500V insulation resistance meter, the insulation resistance is ≥10MΩ. The operating environment temperature range is 0 to +55°C, and the storage temperature is -25 to 70° C.

It is suitable for a humidity environment of 20% to 95% RH without condensation. It should be used in scenarios free of corrosive gases and with a pollution level of 2.

Physical and protective parameters:

It belongs to the built-in module of the disk, with a protection grade of IP30. and adopts natural cooling method. It weighs approximately 130g, occupies one slot, and takes up 14 characters in the I/O area (9 characters for input and 5 characters for output). The external connection is compatible with AWG#23 and below specification wires.

Core functional features

Flexible input delay adjustment

It supports batch adjustment of input delay time through parameters. The delay time for switching from OFF to ON can be selected from multiple Settings such as 0.1ms and 1ms.

It can also set a non-filtering mode. According to the signal characteristics of different equipment in the industrial site, corresponding filtering parameters can be matched to avoid interference signals affecting control accuracy.

Pulse capture and state holding

After the pulse capture register captures a pulse signal, it will set the corresponding bit to "1", and this state will remain until a reset operation is performed through the pulse capture reset flag, which facilitates the controller to stably read pulse-related data and adapt to the control logic triggered by high-frequency signals.

Strong anti-interference and stable operation

It has excellent anti-interference performance, capable of withstanding static interference from ±6kV contact discharge and ±8kV air discharge, and can resist 10V/m radiated electromagnetic field interference at frequencies ranging from 80MHz to 1000MHz.

It can simultaneously withstand vibrations with a single-sided amplitude of 0.15mm and a fixed acceleration of 19.6m/s², as well as impacts with a peak acceleration of 147m/s², making it suitable for complex industrial field environments.

Intuitive signal display:

It is equipped with green and red LED indicator lights, with one point corresponding to one green LED, which lights up when a signal is input. It can also switch the display status in units of 16 points. The red ERR indicator light is used for abnormal alarm, facilitating staff to quickly troubleshoot module operation faults.

Typical application scenarios

This module, with its 32-point input capability and high-speed pulse processing capacity up to 20kHz, is widely used in various industrial automation control systems.

For instance, in machine tool processing, the position pulse signals of the servo motor can be collected to assist in achieving precise processing and positioning of the workpiece.

In the assembly line sorting equipment, capture the high-frequency trigger signals of the sensors to control the start and stop rhythm of the sorting mechanism.

It can also be used in packaging machinery, printing machinery and other equipment to collect pulse signals for counting and positioning, ensuring the accuracy of the equipment's automated operation.
