Mitsubishi FX0N-16EYR (FXON-16EYR) – 16-Point Relay Output Programmable Controller | FX0N Series Platform
The Mitsubishi FX0N-16EYR (also catalogued as FXON-16EYR) is a compact, high-reliability programmable logic controller from Mitsubishi Electric’s FX0N Series. Designed for cost-sensitive yet performance-demanding automation applications, this unit delivers 8 DC inputs and 8 relay outputs in a slim DIN-rail-mountable housing. It is the preferred choice for procurement engineers sourcing proven, field-hardened control hardware for machine OEM, panel building, and process retrofit projects.
Product Positioning: The FX0N-16EYR occupies the entry-to-mid tier of Mitsubishi’s FX family, offering deterministic scan-cycle performance, broad I/O expansion capability via FX0N extension modules, and full compatibility with GX Developer / GX Works2 programming environments — making it a low-risk, long-lifecycle selection for industrial control panels.

- Deterministic scan cycle: Sub-microsecond instruction execution ensures precise timing for high-speed sequencing tasks.
- Wide software ecosystem: Compatible with GX Works2, enabling IEC 61131-3 ladder, SFC, and structured text programming.
- Long product lifecycle: FX0N series has extensive installed base globally, ensuring spare-parts availability and engineering familiarity.
System Architecture & Signal Flow
The FX0N-16EYR integrates the CPU, power supply, and I/O in a single compact housing. Input signals (24 VDC, optically isolated) are scanned each cycle and stored in the input image register. The CPU executes the ladder program against the image registers and writes output states to the relay output coils. Relay contacts switch the connected load circuit independently of the PLC logic voltage, providing galvanic isolation between the control and field circuits. Expansion modules connect via the right-side bus connector, extending the I/O image seamlessly.
Sourcing & Quality Verification

Technical FAQ
- Q: What is the difference between FX0N-16EYR and FXON-16EYR?
- A: They are the same product. “FXON” is an alternate catalogue notation used in some regional markets; the hardware, firmware, and specifications are identical.
- Q: Can the FX0N-16EYR communicate with HMI panels?
- A: Yes. Via the RS-422 port or optional RS-232C/RS-485 adapter, it connects to Mitsubishi GOT series HMIs and most third-party HMIs supporting Mitsubishi FX protocol.
- Q: Is the FX0N-16EYR compatible with GX Works3?
- A: No. GX Works3 supports iQ-R and iQ-F series only. Use GX Works2 or GX Developer for FX0N programming.
- Q: What expansion modules are compatible?
- A: FX0N-8EX, FX0N-8EYR, FX0N-8EYT, FX0N-3A (analog), and other FX0N-series extension units. Maximum 128 total I/O points.
- Q: What is the warranty period?
- A: New units carry a 12-month warranty from date of dispatch. Refurbished units carry a 6-month warranty. Contact us for extended warranty options.
