Product Overview
When space is tight and control requirements are precise, the Mitsubishi FX1S-14MT-001 delivers a compact yet powerful solution. This PLC from the FX1S series offers 14 total I/O points—8 inputs and 6 relay outputs—making it an excellent choice for small mechanical equipment. Operating on AC220V, it provides reliable switching for a variety of industrial applications. Designed for the smallest packages, it is the preferred target for cost-conscious users seeking powerful control over a limited I/O range.
Technical Specifications Breakdown
The FX1S-14MT-001 features 8 input points and 6 output points, all relay type. The input signal uses platinum temperature resistance with a 3-wire, 4-point configuration, and sensor current is 1mA. This module supports up to 4 channels and can be set to Celsius or Fahrenheit. Resolution is 0.2–0.3 degrees, offering high precision. Memory format is EEPROM, with up to 16,000 steps available. No battery support is required. Writing and deleting programs is done via peripheral devices when the unit is installed on the PLC. Total input and output points are 48, with 24 inputs and 24 outputs, all relay type. Power supply voltage is AC100-240V, and input signal voltage is DC24V. RAM memory capacity is 8K, expandable to 16K. CPU arithmetic processing speed is 0.08 µs per basic instruction. The FX2N series can connect input/output expansion modules and special function modules on the right side. The basic unit includes a 2-axis independent maximum 20kHz positioning function (transistor output type). Quick-disconnect terminal blocks improve maintainability. Clock and hour meter functions are standard, along with continuous scanning, input filter adjustment (x000 to x017), note recording, online program editing, RUN/STOP switch, remote maintenance, and password protection.
Industry Applications
This PLC excels in small machinery such as packaging equipment, labeling machines, and simple conveyor systems. The relay outputs handle inductive loads like small motors and solenoids, while the precise temperature input supports monitoring in heating or cooling processes. For maintenance engineers, the compact form factor simplifies panel layout, and the quick-disconnect terminals reduce downtime during servicing.
Installation & Setup Guidance
Mount the FX1S-14MT-001 on a DIN rail or directly to a panel using the provided slots. Ensure the AC220V supply is stable and within the specified range. Connect input devices (sensors, switches) to the 8 input points using the 3-wire platinum resistance configuration. Wire relay outputs to loads, respecting current ratings. Use the RUN/STOP switch on the panel for easy operation. For programming, connect a peripheral device and use the online editor to modify logic without stopping production.
Maintenance & Reliability
Regularly inspect terminal connections for tightness and cleanliness. Verify that the ambient temperature and humidity remain within specified limits. The EEPROM memory retains programs without battery backup, reducing maintenance. The quick-disconnect terminal blocks allow fast replacement of cables, minimizing downtime. Periodic testing of input filters and clock functions ensures consistent performance.
Compatibility & Integration
This module is compatible with FX1N, FX2N, FX3U, FX2NC (via FX2NC-CNV-IF), and FX3UC (via FX2NC-CNV-IF or FX3UC-1PS-5V) PLCs. It can connect to input/output expansion modules and special function modules on the right side of the FX2N series. Serial communication data transmission is supported. For remote maintenance, use modem communications to monitor, upload, or uninstall programs.
Selection Guide & Purchasing Advice
Before ordering, verify your system voltage (AC220V) and I/O count requirements. The FX1S-14MT-001 is ideal for applications needing up to 14 I/O points. For larger systems, consider the FX2N series. SpareTechPLC stocks this model and can provide current lifecycle status and availability. Contact us for replacement options if needed.
Troubleshooting & Common Issues
If the PLC fails to start, check the AC220V supply and RUN/STOP switch position. For input issues, verify sensor wiring and input filter settings. Output problems may stem from relay contact wear or overloads. Use the online programming tool to diagnose logic errors. The password protection feature prevents unauthorized changes.
