FX3U-32MR/ES MITSUBISHI MELSEC FX3U 32 I/O Relay Output PLC Base Unit

The FX3U-32MR/ES MITSUBISHI (Model: FX3U-32MR/ES) is a highly versatile compact programmable logic controller main unit from the Mitsubishi Electric MELSEC FX3U Series. Featuring 16 digital inputs and 16 electro-mechanical relay outputs, the FX3U-32MR/ES MITSUBISHI delivers robust, medium-density logic control and power-switching capabilities for automated industrial machinery, control panels, and process skids.

Powered by an integrated 100-240V AC power supply, the FX3U-32MR/ES MITSUBISHI operates at impressive execution speeds down to 0.065 microseconds per basic instruction. It includes built-in high-speed counter inputs (up to 100 kHz) and supports expansive local and networked I/O options, making it ideal for both standalone processing and networked machine automation.

Key Features of the FX3U-32MR/ES MITSUBISHI

• 32 Onboard Digital I/O Points: Equipped with 16 24V DC sink/source inputs and 16 dry contact relay outputs in a compact base module.

• Heavy-Duty Relay Outputs: Electro-mechanical relay contacts switch up to 240V AC or 30V DC at 2A per point for direct control of solenoids, contactors, and indicators.

• Universal AC Input Power: Integrated 100V to 240V AC power supply with a built-in 24V DC service supply for powering field sensors.

• High-Speed Counter Inputs: Features 6 onboard high-speed counter channels (up to 100 kHz) for fast encoder tracking and frequency counting.

• Large Memory Capacity: Standard 64,000 steps of internal RAM memory, easily expandable via optional FX3U flash memory cassettes.

• Flexible Modular Expansion: Supports right-side I/O blocks and left-side high-speed analog/communication adapters (via FX3U expansion boards).
