FUJI NP1AYH4I-MR current output module

The NP1AYH4I-MR is a multi-range analog 4-channel current output module in the MICREX-SX series of Fuji Electric.

It is often installed on this series of substrates and is responsible for converting InT-type digital data into analog current signals, adapting to signal conversion and control scenarios in industrial automation.

The following is a detailed introduction to its core information:

Core technical parameters

Basic electrical specifications

As a 14-bit resolution current output module, it is suitable for multi-range current output requirements and can accurately complete the conversion from digital signals to analog current signals.

Its internal consumption current is below DC24V 300mA, and this power supply is provided by the power module.

In terms of insulation, optocouplers are used for insulation between the external terminals and the internal logic (signal side) and the insulated power supply (DC/DC converter).

The insulation endurance between the external terminals and the ground reaches AC500V/1 minute, and the insulation resistance is ≥10MΩ under the measurement condition of DC500V.

Environment and physical parameters

The operating environment temperature range is 0 to +55°C, and the storage and transportation temperature is -20 to 70° C.

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

The external dimensions are W35×H105×D111mm (with a protruding part of 21mm), the weight is approximately 240g, the protection grade is IP30. it is a built-in tray type, and it is cooled by natural air cooling.

Structure and interface related:

The detachable terminal block (M3 screw 20 poles) is adopted, occupying 1 slot.

The number of characters occupied in the I/O area is 8 characters for input and 4 characters for output (fixed). It is recommended to use shielded twisted-pair cables for external connections to ensure signal stability.

Core functional features

Flexible range setting

Support setting different ranges for each channel separately to meet the current signal requirements of different devices in industrial scenarios.

It also has the overall switch setting function. After being turned on, there is no need to write an additional range setting application program. However, in this mode, the ranges of all four channels need to remain consistent, taking into account both flexibility and convenience.

Adaptive programming and anti-interference:

Compatible with D300win V2.2.0.0 and above version programmers, facilitating users' program setting and debugging.

It has excellent anti-interference performance, capable of withstanding static interference from ±6kV contact discharge and ±8kV air discharge.

It can also resist 10V/m radiated electromagnetic field interference at frequencies ranging from 80MHz to 1000MHz, ensuring the stability of signal output in complex industrial electromagnetic environments.

Stable operation guarantee

It has good mechanical stability and can withstand vibrations with a single-sided amplitude of 0.15mm and a fixed acceleration of 19.6m/s² (2 hours each for the X, Y, and Z axes), as well as impacts with a peak acceleration of 147m/s² (3 times in each direction).

It can adapt to conventional mechanical vibrations in industrial sites and impacts during transportation.

Typical application scenarios

This module, with its precise multi-range current signal conversion capability, is widely applied in various industrial automation control systems.

For instance, in the sensor signal feedback system of chemical production, the digital instructions output by the controller are converted into current signals that are compatible with the actuators.

In the control circuits of machine tools and assembly line equipment, it provides stable analog current drive signals for components such as servo mechanisms and control valves.

It can also be used in monitoring and control equipment in industries such as power and metallurgy to achieve signal connection between digital systems and analog actuating elements.
