FX3U-80MT/ESS MITSUBISHI MELSEC FX3U 80 I/O Transistor PLC Base Unit

The FX3U-80MT/ESS MITSUBISHI (Model: FX3U-80MT/ESS) is a high-performance compact programmable logic controller main unit from the Mitsubishi Electric MELSEC FX3U Series. Featuring 40 digital inputs and 40 source-type (PNP) transistor outputs, the FX3U-80MT/ESS MITSUBISHI offers high-density onboard control capacity for automated machinery, OEM equipment, and industrial processing systems.

Powered by an integrated 100-240V AC power supply, the FX3U-80MT/ESS MITSUBISHI operates at processing speeds as fast as 0.065 microseconds per basic instruction. It features built-in high-speed counter inputs (up to 100 kHz) and high-speed pulse outputs (up to 100 kHz on 3 axes), making it suitable for multi-axis servo positioning, high-speed counting, and complex machine automation.

Key Features of the FX3U-80MT/ESS MITSUBISHI

• High-Density Onboard I/O: Integrates 40 24V DC inputs and 40 source transistor (ESS / PNP) outputs in a single compact housing.

• Source Transistor Outputs (ESS): Short-circuit protected PNP transistor outputs designed for switching European-standard PNP control logic and solenoid valves.

• Multi-Axis High-Speed Positioning: Includes 3 onboard 100 kHz pulse train outputs for driving servo amplifiers and stepper drives.

• High-Speed Counter Inputs: Features 6 channels of high-speed counters (up to 100 kHz single-phase / 50 kHz A/B phase) for encoder feedback.

• Large Memory & Fast Processing: 64,000 steps of internal RAM program memory with execution speeds down to 0.065 us/instruction.

• Broad Expansion Capacity: Expandable up to 256 local I/O points (or 384 points with CC-Link network I/O) using FX series expansion blocks and adapters.
