Mitsubishi Analog Output Module FX2N-4DA – Extended Overview

The Mitsubishi FX2N-4DA is a high-performance analog output module designed for use with Mitsubishi FX series programmable logic controllers (PLCs). It provides four independent analog output channels, each capable of delivering either voltage or current signals, allowing for flexible control of external devices such as actuators, inverters, valves, and other analog instrumentation.

Signal Types and Ranges

●Voltage output: DC -10V to +10V

●Current output: DC 0 to 20mA

Each channel can be individually configured for either voltage or current output, enabling mixed-signal applications within a single module.

Resolution

●Voltage mode: 11-bit binary plus 1 sign bit (total 12-bit resolution, including sign)

●Current mode: 10-bit binary

This resolution ensures precise analog signal generation suitable for a wide range of industrial control tasks.

Channel Configuration

The module supports 4 independent analog output channels. All channels can be set for voltage or current output independently, providing maximum flexibility for multi-loop control systems.

Compatible PLC Models

The FX2N-4DA is compatible with the following Mitsubishi PLC series:

●FX1N

●FX2N

●FX3U

●FX2NC (requires FX2NC-CNV-IF adapter)

●FX3UC (requires FX2NC-CNV-IF or FX3UC-1PS-5V adapter)

Electrical and Operational Characteristics

●The module is designed for direct connection to the PLC expansion bus, simplifying installation and wiring.

●It supports high-speed data transfer with the PLC for real-time analog output updates.

●Built-in isolation between the output channels and the PLC system helps reduce noise and improve signal integrity.

●The module provides short-circuit protection on output terminals, enhancing system reliability.

●Output accuracy and stability are maintained over a wide temperature range, making it suitable for industrial environments.

Application Examples

●Controlling variable frequency drives (VFDs) for motor speed regulation

●Positioning servo amplifiers with analog velocity or torque commands

●Driving analog-input valves, dampers, or actuators in process control

●Generating reference signals for PID controllers or chart recorders

●Multi-channel signal generation in test and measurement systems

Programming and Configuration

●The module is configured using Mitsubishi’s GX Works2 or GX Developer software.

●Output values are controlled by writing digital data to specific buffer memory addresses.

●Each channel’s output mode (voltage or current) is set via buffer memory settings or hardware switches (depending on the module version).

●The module supports both 8-bit and 12-bit data formats for compatibility with different PLC programming styles.

Physical and Environmental Specifications

●Compact design for mounting on DIN rails or within PLC cabinets

●Operating temperature range: 0°C to 55°C (32°F to 131°F)

●Storage temperature range: -20°C to 70°C (-4°F to 158°F)

●Humidity tolerance: 5% to 95% RH (non-condensing)

●Vibration and shock resistance per industrial standards

Summary

The FX2N-4DA is a versatile, reliable, and easy-to-integrate analog output module for Mitsubishi FX series PLCs. With four individually configurable channels, high resolution, and broad PLC compatibility, it is well-suited for a wide range of automation and process control applications requiring precise analog signal generation.
