FX2N-4DA 4-Channel Analog Output Module 12-bit 4-20mA | Mitsubishi

The Original New Mitsubishi FX2N-4DA is a 4-channel analog output special function block for MELSEC-F FX series PLC systems (FX0N, FX1N, FX2N, FX2NC, FX3U, FX3UC). It converts digital values from the PLC into precise analog signals for industrial control applications. Each of the 4 output channels can be independently configured for voltage (-10 to +10V DC, 0-10V DC, 0-5V DC) or current (4-20mA DC, 0-20mA DC) via wiring selection. All four channels update simultaneously with a conversion speed of 2.1ms. The module features a 12-bit resolution (5mV for voltage, 20µA for current) and is programmed via buffer memory (BFM) using FROM/TO instructions. The module draws 30mA from the 5V rail of the FX2N main unit or powered extension unit. This product is discontinued and available as a spare part for maintaining existing FX2N-based systems.

⚠️ Important Product Status Note:

This product has been discontinued by Mitsubishi Electric as of December 2015. The recommended replacement is the FX3U-4DA (for FX3U/FX3G series PLCs) or FX5-4DA-ADP (for MELSEC iQ-F series). This product remains available as a spare part for maintaining existing FX2N-based systems while supplies last. For new installations, please consider the recommended replacement models.

Core Engineering Highlights:

Key Features:

• Original New Mitsubishi FX2N-4DA module

• 4 analog output channels, individually configurable for voltage or current per channel

• Voltage output: -10 to +10V DC (resolution 5mV), 0-10V DC, 0-5V DC

• Current output: 0-20mA DC, 4-20mA DC (resolution 20µA or 4µA)

• 12-bit high-precision resolution for accurate analog control

• 2.1ms conversion time for all 4 channels (number of selected channels does not affect speed)

• Output range selection via wiring for each channel

• Occupies 8 I/O points from the PLC allocation

• 32 buffer memory (BFM) locations for mode settings, output data storage, offset/gain adjustment

• Offset and gain adjustment per channel for calibration

• Photocoupler isolation between analog output area and PLC; DC/DC converter isolation for power supply

• Screw terminal block for secure and reliable field wiring

• DIN rail mounting for space-efficient installation

• Compatible with FX0N, FX1N, FX2N, FX2NC, FX3U, FX3UC series PLCs

Applications:

• Speed reference control for variable frequency drives (VFDs) and servo systems

• Positioning of proportional valves and electric actuators

• Process control analog signal generation (4-20mA current loops)

• Legacy system spare part replacement for FX2N PLC configurations

• OEM equipment requiring multi-channel analog output

Technical Specifications:

Buffer Memory (BFM) Allocation:

• BFM #0: Output mode selection (voltage/current per channel)

• BFM #1 to #4: Digital value output data for channels 1 to 4

• BFM #5: Output data in STOP mode setting

• BFM #10 to #13: Offset data per channel

• BFM #14 to #17: Gain data per channel

• Refer to the FX2N-4DA User's Manual (JY992D65901a) for complete BFM details

Output Modes (BFM #0):

• 0: -10 to +10V → digital value -2000 to +2000

• 1: 4 to 20mA → digital value 0 to +1000

• 2: 0 to 20mA → digital value 0 to +1000

Compatibility:

• Compatible PLC series: FX0N, FX1N, FX2N, FX2NC, FX3U, FX3UC

• Connects directly to the right side of the main unit or extension units

• For connection to FX3UC or FX3GC, FX2NC-CNV-IF or FX3UC-1PS-5V adapter is required

• Up to 8 special function modules can be connected (depends on PLC main unit type)

Recommended Replacement:

• FX3U-4DA: 4-channel analog output block for FX3U series. Provides 16-bit resolution for voltage and 15-bit for current, offering significantly higher resolution than FX2N-4DA. Compatible with FX3G, FX3GE, FX3GC, FX3U, FX3UC series PLCs. Note that buffer memory addresses and output mode settings differ from FX2N-4DA; program migration is required.

• FX5-4DA-ADP: 4-channel analog output adapter for MELSEC iQ-F (FX5U, FX5UC) series for new system designs.
