FX1N-24MR-D Mitsubishi Digital Input Module

Product  Description：

A Mitsubishi Digital Input Module is a hardware interface designed to convert external DC or AC electrical signals into digital logic data that the PLC’s Central Processing Unit (CPU) can process. These modules are known for their rugged industrial design, high-speed processing capabilities, and varying densities—ranging from 8-point modules for small tasks to 64-point high-density modules for complex automation.

Product Parameters

While specific values vary by model (e.g., QX40 vs. RX40C4), the following parameters define the performance of these modules:

• Input Type: Available in DC (Sinking or Sourcing) and AC variants.

• Number of Points: Common configurations include 16, 32, or 64 points per module.

• Rated Input Voltage: Standard options include 12V DC, 24V DC, and 100-240V AC.

• Rated Input Current: Typically ranges from 4mA to 6mA per point for DC modules.

• Response Time: Adjustable filter times, often ranging from 0.1ms to 70ms to prevent noise interference.

• Isolation Method: Photocoupler isolation is standard to protect the internal PLC circuitry from external electrical surges.

• Connection Type: Removable terminal blocks, 40-pin connectors, or MIL connectors depending on the density.

Product Advantages

Mitsubishi modules are preferred in the industry for several key reasons:

• Exceptional Reliability: Built with high-quality components that withstand harsh electromagnetic interference (EMI) and vibrations.

• High-Speed Processing: Minimal delay between signal detection and CPU updates, which is critical for precision manufacturing.

• Scalability: The modular design allows users to expand their I/O count easily without replacing the entire system.

• Diagnostic Features: Many modules include LED indicators for each point and software-based diagnostics to identify wiring faults or disconnected sensors.

• Energy Efficiency: Low power consumption designs reduce the heat load within control cabinets.

Precautions for Use

To ensure long-term stability and safety, users should adhere to the following guidelines:

• Wiring Polarity: For DC modules, ensure the distinction between "Sinking" (NPN) and "Sourcing" (PNP) logic matches your field devices.

• Voltage Limits: Never exceed the rated voltage, as this can permanently damage the photocouplers.

• Noise Mitigation: Keep high-voltage power lines separate from digital input signal cables to prevent "ghost" signals.

• Terminal Tightening: Periodically check terminal screws; loose connections can lead to intermittent signal loss or overheating.

• Environment: Ensure the module is operated within the specified temperature and humidity ranges, typically 0 to 55 degrees Celsius.

Product Applications

These modules are used across virtually every sector of industrial automation:

• Automotive Assembly: Monitoring the position of robotic arms and the presence of parts on a conveyor.

• Packaging Machinery: Detecting bottle fill levels, cap presence, and emergency stop triggers.

• Semiconductor Manufacturing: High-speed tracking of wafers through vacuum chambers and lithography tools.

• Building Automation: Managing HVAC sensors, lighting switches, and security gate inputs.

• Water Treatment: Reading float switches and pressure sensors to regulate pump operations.
