Product Overview
When your factory automation demands a reliable and flexible controller for digital input and output control, the Mitsubishi FX2N-16MR-001 delivers a proven solution. This main processing unit (MPU) from the FX2N series provides 16 total I/O channels with relay output, making it suitable for a wide range of industrial applications. Its compact footprint and built-in features allow you to manage up to 256 points when expanded, offering scalability for growing production lines.
Technical Specifications Breakdown
The FX2N-16MR-001 operates on a supply voltage of 100-240VAC, allowing direct connection to standard mains power. It consumes only 20W, keeping energy costs low. The unit features 8 input points and 8 output points, all with relay output type for robust switching of loads. Built-in 8K step RAM memory is standard, expandable to 16K for larger programs. The CPU processes basic instructions at 0.08 microseconds, ensuring fast logic execution. Dimensions are 130x90x87 mm (WxHxD), and weight is 0.6 kg.
Industry Applications
This PLC excels in discrete manufacturing environments such as packaging lines, material handling systems, and simple machine control. For example, in a conveyor sorting system, the 8 inputs can read sensor signals while the 8 relay outputs drive actuators or motor contactors. The relay output type provides galvanic isolation and can switch AC or DC loads up to typical relay ratings, making it versatile for mixed voltage systems.
Installation & Setup Guidance
Mount the FX2N-16MR-001 on a DIN rail or panel using the provided slots. Ensure adequate ventilation around the unit. Connect the 100-240VAC supply to the designated terminals. Wire input devices (sensors, switches) to the input terminals and output loads (relays, contactors) to the output terminals. Use the quick-disconnect terminal blocks for easy maintenance. The built-in 8K EEPROM memory retains the program without a battery, simplifying startup and reducing maintenance.
Maintenance & Reliability
The relay outputs have a finite mechanical life; for high-cycle applications, consider derating or using external solid-state relays. Periodically inspect terminal connections for tightness and cleanliness. The unit's low power consumption (20W) reduces heat buildup, contributing to long service life. The FX2N series is known for robust construction, and the 0.6 kg weight indicates solid build quality.
Compatibility & Integration
This main unit can connect to FX2N series input/output expansion modules and special function modules on its right side, allowing you to increase I/O count or add analog, temperature, or communication capabilities. For serial communication, install an FX2N-232-BD or FX2N-485-BD board (not included) to enable RS232, RS485, or RS422 links. The transistor output variant (MT) offers high-speed pulse outputs, but the MR model focuses on reliable relay switching.
Selection Guide & Purchasing Advice
Before purchasing, verify that your application requires exactly 8 inputs and 8 relay outputs. If you need more I/O, consider the FX2N-30MR model (16 inputs, 14 outputs) or add expansion modules. The FX2N-16MR-001 is ideal for small to medium machines. SpareTechPLC stocks this model and can advise on compatibility with your existing system.
