FX3UC-16MR/DS-T - Mitsubishi Programmable Controllers Melsec

Engineered by Mitsubishi Electric, the FX3UC-16MR/DS-T stands out for its balance of size, capability, and reliability. Operating on a 24V DC power supply, this PLC integrates 8 digital inputs and 8 relay outputs, offering precise control over automation processes in limited panel spaces. The unit features a program memory of 64K steps (EEPROM), enabling storage of complex control logic while ensuring data retention during power outages.

With a power consumption of just 6W and support for up to 256 local I/O points (expandable to 384 with remote modules), the FX3UC-16MR/DS-T provides scalability without compromising speed. It maintains LD instructions at 65 ns and MOV instructions at 642 ns, making it suitable for moderate-speed control loops in real-time applications. The buffer battery ensures data backup, and compliance with global standards like CE, UL/cUL, and UKCA certifications guarantees international installation flexibility.

The module offers solid protection with its IP10-rated enclosure and IEC 60068-2-6 vibration compliance, making it a dependable choice for demanding industrial conditions. A compact footprint (only 34 mm wide) enables easy mounting in dense cabinets, while the optional 2-wire RS-485 interface and integrated EMC filtering ensure clean signal integrity and seamless network communication. Trusted in automotive, packaging, and light manufacturing sectors, this MELSEC-F Series PLC delivers proven durability and adaptability.
