Mitsubishi Electric FX2N 2DA Specification

The Mitsubishi Electric FX2N-2DA is a versatile and compact analog output module designed for use with the FX2N series of programmable logic controllers. This module enhances the functionality of PLC systems by providing two analog output channels, allowing for precise control of devices that require variable voltage or current signals. Each channel can output a voltage range of 0 to 10V or a current range of 4 to 20mA, making the module suitable for a wide array of industrial applications, such as driving actuators or controlling variable speed drives.

The FX2N-2DA is engineered to seamlessly integrate with the FX2N series base units, ensuring compatibility and ease of installation. It employs a 12-bit digital-to-analog conversion process, providing high-resolution output that ensures accurate and reliable signal representation. The module features a robust build, designed to withstand the rigors of industrial environments, and operates within a temperature range of 0 to 55 degrees Celsius. It also supports a wide power supply voltage range, from 20.4 to 28.8V DC, offering flexibility in different setups.

In terms of communication, the FX2N-2DA connects to the base unit via a dedicated expansion bus, which facilitates seamless data exchange and ensures rapid response times. Its compact design allows for space-efficient integration into control panels, and its low power consumption contributes to overall system efficiency. The module is equipped with LED indicators for easy monitoring of operational status and fault conditions, aiding in quick diagnostics and maintenance. Overall, the Mitsubishi Electric FX2N-2DA is a reliable solution for enhancing analog control capabilities in industrial automation systems.

Mitsubishi Electric FX2N 2DA F.A.Q.

How do I connect the Mitsubishi FX2N-2DA to my PLC system?

To connect the FX2N-2DA to your PLC system, ensure that the module is mounted on a DIN rail adjacent to the base unit. Connect the extension cable from the base unit to the FX2N-2DA and ensure that the power supply is correctly wired to the module.

What are the steps to configure the analog output channels on the FX2N-2DA?

To configure the analog output channels, first designate the channel settings in your PLC program. Use the appropriate FROM/TO instructions to set the output values. Refer to the programming manual for specific register settings.

How can I troubleshoot if the FX2N-2DA module is not outputting the correct voltage/current?

Check all wiring connections for secure contact. Verify the configuration settings in the PLC program and ensure that the correct registers are being used. Additionally, measure the output using a multimeter to confirm the output levels.

What maintenance is required for the FX2N-2DA module to ensure optimal performance?

Regularly inspect the module for dust and debris and clean with a soft brush or compressed air. Ensure that all connections are tight and free from corrosion. Periodically check the output levels to ensure accuracy.

Can the FX2N-2DA be used with both voltage and current output simultaneously?

No, the FX2N-2DA cannot output both voltage and current simultaneously on the same channel. Each channel can be configured for either voltage or current, but not both at the same time.

How do I update the firmware on the FX2N-2DA module?

Mitsubishi FX2N-2DA modules do not typically require firmware updates as they are designed for specific hardware functionality. Ensure you have the latest PLC programming software for best compatibility.

Is it possible to expand beyond two analog outputs with the FX2N-2DA?

To expand beyond two analog outputs, additional FX2N-2DA modules can be connected to the PLC system. Each module provides two extra analog outputs. Ensure your PLC system can handle the additional modules.

What precautions should be taken when wiring the FX2N-2DA?

When wiring the FX2N-2DA, ensure that power is off to prevent electrical shock. Use shielded cables to minimize electrical noise, and follow the wiring diagrams provided in the manual to prevent incorrect connections.

How do I reset the FX2N-2DA module to factory settings?

The FX2N-2DA does not have a factory reset function. Configuration settings are controlled through the PLC software, and you can reprogram the relevant registers to the default state as needed.

What is the maximum load the FX2N-2DA can handle on its output channels?

The FX2N-2DA can handle a maximum load of 600 ohms for current output (4-20mA) and a minimum load of 2k ohms for voltage output (0-10V). Ensure your connected devices fall within these parameters.
