Mitsubishi MELSEC iQ-F FX5U Compact PLC

The Mitsubishi MELSEC iQ-F FX5U Compact PLC is the flagship of Mitsubishi Electric's compact controller family, bridging the gap between entry-level micro-PLCs and mid-range modular systems with a feature set that was previously unavailable below the MELSEC Q series. The FX5U supports 32 to 256 I/O points (onboard + expansion) with execution speeds of 34 ns per basic instruction, making it one of the fastest compact PLCs available for Saudi Arabia's OEM machine market. Standard onboard connectivity includes a built-in Ethernet port (100 Mbps) for Modbus TCP/IP, EtherNet/IP (adapter), and MC protocol communications, an SD card slot for data logging and program backup, and a USB mini-B port for engineering laptop connection — all without requiring additional communication modules or extra budget.

The FX5U supports IEC 61131-3 structured text, ladder diagram, function block diagram, and sequential function chart programming in GX Works3 software, enabling Saudi automation engineers to apply modern software engineering practices — version control, modular program design, structured documentation — to compact machine PLC projects. Its motion positioning function supports up to 4 axes of open-collector or differential pulse output positioning without a motion module, covering the majority of simple pick-and-place, XY table, and indexing applications. The built-in analog I/O (2 input, 1 output) eliminates the need for a separate analog module in many process control applications, further reducing system cost and panel space.

The FX5U is widely adopted across Saudi Arabia's fast-growing OEM manufacturing sector, where the National Industrial Development & Logistics Programme (NIDLP) and MODON industrial city expansion are driving investment in locally produced food processing, packaging, and light industrial machinery. The FX5U's combination of Ethernet connectivity, SD card data logging, and 256-point expansion capacity gives Saudi machine builders a PLC capable of integrating into Industry 4.0 factory architectures — connecting to MES systems via EtherNet/IP and logging production data to SD card for OEE analysis — at a compact PLC price point. NWC district pressure station panels across Saudi municipalities also deploy FX5U for multi-pump sequencing, where the built-in Ethernet connects to SCADA via Modbus TCP.

Razz Middle East holds comprehensive FX5U stock in Riyadh including main units (32MT, 64MT, 80MT), expansion I/O modules, and communication cards. Our automation engineers provide full project services from specification to commissioning for Saudi machine builders and end-user projects. Sample units are available for OEM evaluation programmes. SAR pricing with 18-month warranty is provided within 2 hours of RFQ.
