PC-based IO board with Smart Interrupt function

Introducing the new AX92351 DiO Board, available in both 32-channel and 64-channel configurations, with standout features designed to enhance industrial automation and control systems:

Key Features:

• PCIe x1 Interface: Ensures high-speed, reliable connectivity.
• Isolated Inputs/Outputs: Choose between 16 isolated DI (Digital Input) and 16 isolated DO (Digital Output), or 32 isolated DI and 32 isolated DO, depending on your requirements.
• Smart IRQ (Interrupt Function): Allows any combination of DI to trigger interrupts (INT0/INT1), ensuring real-time responsiveness.
• Advanced Digital Filter: Each DI input supports up to 16 filter stages to eliminate signal noise and ensure accurate data processing.
• Comprehensive Programming Support: Includes DLLs for seamless integration with C, C#, C++, and LabVIEW applications.

One of the AX92351’s standout features is the ability of its DI channels to support both sink and source input types, offering maximum flexibility for various industrial applications. Its smart IRQ function, paired with digital filtering, makes it highly suitable for demanding environments like factory automation, ON/OFF control, and switch status sensing.

Enhanced Performance for Critical Inputs

The AX92351 card features smart interrupt technology, allowing instantaneous input response without overloading the computer system. This is particularly beneficial when dealing with critical inputs from sensors or fast pulses from industrial equipment. The smart interrupt reduces the need for constant input scanning, optimizing system performance.

Digital Filtering for Noise Reduction

To ensure signal accuracy, the AX92351’s digital input channels come equipped with a digital filtering function. This feature filters out noise by defining a minimum pulse width for high/low signals. Signals shorter than the set time width are automatically filtered out, preventing inaccurate pulse counts. Each digital input channel includes 16 filter stages, and each stage can be independently configured for optimal performance.

The AX92351 DiO Board is engineered to meet the demands of industrial environments, providing flexibility, accuracy, and high-speed response for critical automation tasks.

The pictures above show how Smart interrupt can be designed and set in the software to handle instantaneous response on inputs or a combination of inputs triggered. With this feature, the computer system will not be overloaded with excessive scanning of the inputs especially in handling some critical inputs from the devices, sensors, and fast response pulse from other instruments.

The AX92351 card’s digital input supports digital filter time function to help filter out noise that can affect the accuracy of the pulse count. The digital filter defines the pulse time width for high/low signals. Signals with time width less than the defined value will be filtered out. Each digital input channel has 16 filter stages and each stage can be set independently with a specific filter time

Beside the industrial PC products and solutions, Axiomtek Malaysia offers Variety of industrial PCIe IO boards for machine building and Automation includes Multiple serial IO, Remote IO modules, Motion control board, Real Time High speed DIO etc for reliable machine control and automation.
