Product Introduction
When your factory automation system demands reliable control, the Mitsubishi FX2N-48MR-001 delivers. This Fx2n Series Programmable Controller manages up to 48 input/output points, with 24 inputs and 24 relay outputs. Powered by 100-240VAC, it consumes 50VA. The compact design (182x90x87 mm, 0.85 kg) fits easily into control panels. Built-in 8K RAM memory extends to 16K, and the CPU processes basic instructions in 0.08 microseconds. For maintenance engineers, this means fast, dependable operation with straightforward service access.
Technical Specifications Breakdown
- Max I/O Points: 48 points total — 24 inputs and 24 outputs. This provides balanced control for medium-sized applications.
- Output Type: Relay. Relay outputs handle higher currents and offer electrical isolation, making them robust for switching inductive loads like motors and solenoids.
- Power Supply: 100-240VAC. This wide range accommodates global voltage standards, reducing the need for external transformers.
- Power Consumption: 50VA. Low power draw minimizes heat buildup in enclosures, enhancing reliability.
- Memory: 8K RAM (expandable to 16K). Sufficient for complex logic sequences, with room for expansion.
Industry Applications
In packaging lines, the FX2N-48MR-001 controls conveyor sequencing and actuator timing. Its relay outputs directly switch 24VDC sensors and pneumatic valves. For material handling systems, the 24 inputs monitor limit switches and photo-eyes, while the 24 outputs drive motor contactors. The quick-disconnect terminal blocks simplify maintenance — engineers can replace cables without rewiring the entire panel. This reduces downtime during shift changes or emergency repairs.
Installation & Setup Guidance
Mount the FX2N-48MR-001 on a DIN rail inside a clean, dry enclosure. Ensure adequate ventilation around the unit to dissipate the 50VA heat load. Connect the 100-240VAC supply to the dedicated power terminals. For input wiring, use 24VDC sensors; the PLC accepts DC24V input signals. Outputs are relay type — verify load current does not exceed relay ratings. The RS-422 function expansion board enables serial communication for programming and monitoring.
Maintenance & Reliability
From a maintenance engineer’s perspective, the FX2N-48MR-001 offers easy serviceability. The quick-disconnect terminal blocks allow fast module replacement without disturbing field wiring. Periodically inspect the relay outputs for contact wear, especially in high-cycle applications. Keep the enclosure free of dust and moisture to extend component life. The built-in 8K RAM retains programs during power loss, but consider a backup battery for extended memory retention.
Compatibility & Integration
This PLC integrates with Mitsubishi’s FX2N series expansion modules and special function modules. Connect input/output expansion units on the right side of the base unit. The RS-422 communication port supports programming via GX Developer or similar software. For analog control, add the analog output expansion board (1 channel). The 2-axis positioning function (transistor output type) is available on other models, but the FX2N-48MR-001 focuses on reliable relay control.
Selection Guide & Purchasing Advice
Before ordering, verify your I/O count: this model provides exactly 24 inputs and 24 relay outputs. Confirm the 100-240VAC supply matches your facility voltage. The 0.85 kg weight and 182x90x87 mm dimensions fit standard enclosures. For replacement or new installations, SpareTechPLC stocks the FX2N-48MR-001 and compatible accessories.
