Mitsubishi FX2NC-CNV-IF – Extension Bus Conversion Module | MELSEC FX2NC Series
Engineering Background
The MELSEC FX2NC series was engineered by Mitsubishi Electric for space-constrained machine control applications where compact form factor and high I/O density are critical. The FX2NC-CNV-IF serves as the essential interface bridge that unlocks the full expansion capability of the FX2NC CPU by enabling connection to the broader FX2N expansion unit ecosystem.
Product Positioning
Designed for OEM machine builders and system integrators who require maximum I/O flexibility within a minimal cabinet footprint, the FX2NC-CNV-IF eliminates the need for a separate FX2NC-series expansion bus, allowing engineers to leverage existing FX2N peripheral investments alongside FX2NC main units. It is the standard-specified conversion interface for all FX2NC CPU expansion configurations.

System Architecture & Signal Flow
The FX2NC-CNV-IF installs directly onto the right side of the FX2NC CPU unit via the compact extension connector. It converts the FX2NC proprietary compact bus signals to the standard FX2N extension bus format, allowing up to 8 FX2N extension modules (I/O blocks, special function modules, or communication adapters) to be cascaded downstream. Signal integrity is maintained through the conversion without introducing additional scan-cycle latency.
Typical Configuration:
FX2NC CPU → FX2NC-CNV-IF → FX2N-32EX (Input Extension) → FX2N-2AD (Analog Input) → FX2N-232-BD (Serial Communication)

Technical FAQ
Q: Can the FX2NC-CNV-IF connect FX3U or FX3G expansion modules?
A: No. The FX2NC-CNV-IF is designed exclusively for FX2N-series expansion units. FX3U/FX3G expansion requires the FX3UC-1PS-5V or FX3UC-CNV-ADP adapters.
Q: How many FX2N expansion modules can be connected downstream?
A: Up to 8 FX2N extension modules can be connected, subject to the total I/O point limit and power budget of the FX2NC CPU.
Q: Does the FX2NC-CNV-IF require any configuration in GX Works2?
A: No configuration is required. The module is automatically recognized by the FX2NC CPU during power-up hardware scan.
Q: Is this module compatible with FX2NC-32MT-D (DC input/transistor output) variants?
A: Yes. The FX2NC-CNV-IF is compatible with all FX2NC CPU variants regardless of I/O type.
Q: What is the lead time for out-of-stock units?
A: Standard lead time is 3–7 business days for in-stock units. For special orders, contact us for a confirmed delivery schedule.
