Compatible Replacement & Equivalent Models
When the FX2N-16EX-ES/UL is discontinued, unavailable, or requires a cost-effective alternative, the following models offer functional compatibility or direct replacement capability:
- Mitsubishi FX2N-16EX — Standard 16-point input module for FX2N; identical I/O count, without ES/UL certification markings. Direct functional equivalent for non-UL applications.
- Mitsubishi FX3U-16EX — FX3U-series 16-point input expansion; backward-compatible with FX2N base units via FX2N-CNV-BC adapter. Recommended upgrade path.
- Mitsubishi FX3G-16EX/ES-L — Compact FX3G-series equivalent; suitable for space-constrained panel designs.
- Mitsubishi FX5U-16EX/ES — FX5U-series high-speed input module; requires FX5 base unit. Ideal for new system designs replacing legacy FX2N.
- Mitsubishi FX2N-32EX — 32-point input expansion; use when additional I/O consolidation is required in a single slot.
Note: Always verify bus compatibility and power budget before substituting expansion modules. Contact Konmask for cross-reference verification.

Typical Applications
- Machine tool control and CNC auxiliary I/O expansion
- Conveyor and material handling systems
- Packaging and labeling machinery
- HVAC and building automation panels
- Water treatment and pump station monitoring
- Automotive assembly line control
- Food and beverage processing equipment
- Textile and printing machinery
System Compatibility
The FX2N-16EX-ES/UL is compatible with the following Mitsubishi FX2N base units and system configurations:
- Base Units: FX2N-16MR, FX2N-32MR, FX2N-48MR, FX2N-64MR, FX2N-80MR, FX2N-128MR (and MT/ES/UL variants)
- Maximum Expansion: Up to 8 expansion modules per FX2N base unit (subject to I/O point and power budget limits)
- Special Adapters: Compatible with FX2N-CNV-BD for communication board integration
- Not Compatible With: FX1S, FX1N series (different bus architecture); FX5U series (requires FX5 expansion bus)
Selection Guide
Use the following criteria to select the correct expansion module for your application:
- I/O Count: Choose FX2N-16EX-ES/UL for 16 additional input points. For 32 points, consider FX2N-32EX.
- Certification Requirement: ES/UL suffix indicates UL Listing — required for North American installations. Standard FX2N-16EX is sufficient for non-UL markets.
- Input Voltage: Confirm field devices operate at 24 VDC. For AC input applications, consider FX2N-16EX-A1 (100–120 VAC input).
- Response Time: Default 10 ms suits most applications. For high-speed counting or encoder inputs, use dedicated FX2N-1HC or FX2N-4HSX modules instead.
- Future Expansion: If migrating to FX3U or FX5U platform, select FX3U-16EX or FX5U-16EX/ES for forward compatibility.
- Power Budget: Each FX2N-16EX-ES/UL consumes 90 mA from the 5 VDC bus. Verify total expansion current does not exceed base unit supply rating.

Replacement & Compatibility FAQ
Q: Can I use FX2N-16EX-ES/UL with an FX3U base unit?
A: Yes, with the FX2N-CNV-BC adapter, FX2N expansion modules can be connected to FX3U base units. However, Mitsubishi recommends using native FX3U expansion modules for new designs.
Q: What is the difference between FX2N-16EX and FX2N-16EX-ES/UL?
A: The ES/UL variant carries UL Listing certification, required for installations in North America. Functionally, both modules are identical.
Q: Is the FX2N-16EX-ES/UL still in production?
A: The FX2N series has reached end-of-life status with Mitsubishi Electric. Konmask maintains stock of genuine new-old-stock (NOS) and sourced units. Contact us for current availability.
Q: Can this module handle 120 VAC inputs?
A: No. The FX2N-16EX-ES/UL accepts 24 VDC inputs only. For AC input requirements, use the FX2N-16EX-A1 (100–120 VAC) variant.
Q: How many FX2N-16EX-ES/UL modules can I connect to one base unit?
A: Up to 8 expansion modules total (combined input and output), subject to the base unit’s 5 VDC bus current limit. Always calculate total expansion current before finalizing the configuration.
Q: Do you provide a datasheet or wiring diagram?
A: Yes. Contact support@konmask.com to request the official Mitsubishi FX2N-16EX-ES/UL hardware manual and wiring diagrams.
