Mitsubishi MELSEC FX5U-64MT Ethernet PLC

The Mitsubishi MELSEC FX5U-64MT/ESS Ethernet PLC is the top-specification model in Mitsubishi Electric's highly successful FX5U compact PLC series, integrating 32 transistor source outputs and 32 DC 24 V digital inputs in a single base unit that occupies less than 180 mm of panel DIN rail. What distinguishes the FX5U from previous FX-series generations — and from competitive compact PLCs in the Saudi market — is the built-in EtherNet/IP and SLMP (Seamless Message Protocol) communication port as standard, enabling direct integration with Rockwell ControlLogix, Omron Sysmac, and any EtherNet/IP-compliant device without a dedicated gateway module. This dramatically reduces total system cost in Saudi panel builders' projects where mixed-brand automation architectures are the norm rather than the exception, as they frequently are in the oil and gas downstream and water treatment sectors.

The FX5U-64MT features built-in data logging to SD card — capable of recording up to 100 triggers of 10,000 data points each — without any specialist data logger software or additional hardware, enabling direct traceability of process conditions for Saudi Aramco quality management systems, Saudi Food and Drug Authority (SFDA) regulatory compliance records in pharmaceutical and food-processing facilities, and MAADEN production batch records in mining and processing operations. The built-in high-speed counter function handles up to 200 kHz pulse inputs on six channels simultaneously, supporting encoder position feedback, flowmeter totalisation, and cam switch applications without requiring dedicated high-speed I/O expansion cards. Motion control of up to 8 axes via built-in SSCNETIII/H (optical) or pulse output removes the traditional barrier between compact PLC and motion control, allowing simple multi-axis positioning applications — rotary indexing tables, labelling machines, carton erectors — to be solved with a single controller without a separate servo motion module.

The Saudi automation market for compact PLCs is driven by the rapid growth of local manufacturing under Vision 2030's National Industrial Development and Logistics Programme (NIDLP), with new facilities for food processing, pharmaceuticals, medical devices, construction materials, and consumer goods being established across MODON industrial cities in Riyadh, Jeddah, Dammam, Khamis Mushait, and Taif. The FX5U-64MT's compact size, built-in EtherNet/IP, and GX Works3 IEC 61131-3 programming environment make it the preferred controller for Saudi OEM machine builders supplying these facilities, as it allows engineers trained on any IEC-compliant PLC brand to adapt to Mitsubishi quickly without extensive retraining. The 50°C ambient rating and conformal coating option ensure reliable operation in the humid coastal environments of Jeddah, Yanbu, and Jizan where uncontrolled panel temperatures can challenge lower-rated compact PLCs.

Razz Middle East is a certified Mitsubishi Electric distributor with local stock of FX5U-64MT/ESS and key expansion modules in Riyadh. We offer GX Works3 programming software licensing, one-day QuickStart application development workshops for Saudi panel builders, and remote programming assistance. Our engineers can develop complete FX5U application programs for standard Saudi process control applications — pump control, conveyor sequencing, batch control — from our Riyadh office. SAR pricing and delivery schedules are provided within four working hours of RFQ. Volume pricing for OEM orders exceeding 10 units per month is available on application.
