Mitsubishi FX3U-80MR/DS | MELSEC-F FX3U Series PLC

1. Product Overview 📄

2. Core Advantages & Key Features ⭐

1. Stable DC 24 V Power Supply Design
   
   
   Rated DC 24 V operating voltage (allowable range: DC 16.8 V ~ 28.8 V), low power consumption of 45 W. It can keep normal operation under instantaneous power failure within 5 ms, adapting to industrial power grid fluctuations.
2. Dual-mode Digital Input
   
   
   40 DC 24 V universal digital inputs support both sink and source types, compatible with mainstream proximity sensors, photoelectric sensors and limit switches on the market for flexible wiring and configuration.
3. Reliable Relay Output
   
   
   40 relay contact outputs feature strong load capacity, suitable for AC/DC mixed load circuits. With a response time of about 10 ms, it works well for low-speed on-off control of ordinary actuators and has excellent anti-surge performance.
4. Large Program Memory & Fast Operation
   
   
   Built-in 64K steps RAM program memory, supporting extended memory cassette. High-speed instruction processing ensures efficient execution of complex logic, floating-point operation and string processing programs.
5. Powerful Expansion Capability
   
   
   The maximum local I/O points reach 256, and the total I/O points can be expanded to 384 when matching remote I/O modules. It supports connection with multiple special function modules such as positioning, communication and analog modules to expand control functions.
6. Diversified Communication Interfaces
   
   
   Standard RS-422 communication port is reserved, supporting serial communication, Modbus protocol and connection with Mitsubishi HMI, frequency converters and other equipment to realize data interaction of the whole system.
7. Complete Built-in Functions
   
   
   Integrated high-speed counter, pulse function, real-time clock, RUN/STOP switch and online program writing function, convenient for on-site debugging, program modification and equipment maintenance.
8. Industrial-grade Durability
   
   
   Compact structure with standard DIN rail mounting. Wide working temperature range and good vibration resistance, suitable for long-term continuous operation in harsh workshop environments.
