Functional Description
Channel Configuration
The FX2N-4DA offers flexible channel configuration options. Each of the four channels can be independently set to either voltage or current output mode through software configuration. This flexibility allows users to tailor the module to specific application requirements without hardware modifications.
Programming Interface
The module communicates with the FX2N PLC through FROM/TO instructions in the ladder logic program. Buffer memory areas are used to set output modes, write digital values, and read status information. The programming is straightforward and follows Mitsubishi's standard communication protocol for special function modules.
Output Characteristics
In voltage mode, the module provides 0-10V DC output with a maximum load current of 2mA. In current mode, it delivers 4-20mA output with a maximum load resistance of 500Ω. The 4-20mA current loop provides inherent noise immunity, making it suitable for industrial environments with electrical interference.
Application Tip: For optimal performance in current mode applications, ensure proper grounding and use shielded cables for signal transmission to minimize electrical noise interference.
Installation and Wiring
The FX2N-4DA module installs directly onto the FX2N PLC base unit or extension unit. The connection diagram (shown in image 3) illustrates the proper wiring configuration for both voltage and current output modes. Key installation considerations include:
- Proper grounding of the module and connected equipment
- Use of appropriate cable types for analog signal transmission
- Separation of analog signal cables from power cables to prevent interference
- Verification of power supply requirements (24V DC external power)
Applications in Industrial Automation
The FX2N-4DA finds extensive application in various industrial sectors:
Process Control Systems
In chemical plants, food processing, and pharmaceutical manufacturing, the module controls process variables such as temperature, pressure, flow rate, and pH levels through analog actuators and control valves.
Motion Control
For controlling variable frequency drives (VFDs) and servo systems, the analog outputs provide speed and torque reference signals with high precision and stability.
Environmental Control
In HVAC systems and clean room environments, the module regulates temperature, humidity, and pressure control systems through analog output signals to actuators and dampers.
Test and Measurement
Laboratory equipment and test benches utilize the FX2N-4DA for generating precise analog signals for calibration and testing purposes.
