Can I connect this PLC directly to a 220V AC power source?

No, this PLC strictly requires a DC 24V power supply. Connecting it to AC or 220V will instantly burn out the control board.

Is this board compatible with my existing HMI touch screen?

Yes, it can connect to the vast majority of commercially available HMI touch screens and text displays, provided the wiring and communication protocols are set correctly.

Why can't my computer connect to the PLC using the DB9 cable?

Ensure your ladder logic project is open or newly created in the software before attempting to read/write. Also, verify that your COM port is correct and the baud rate is set to 9.6K for the FX1N protocol.

Does this board come with a pre-written program for my machine?

No, the PLC is sold as a blank hardware carrier. You must write your own ladder logic program or import an existing one to control your specific machinery.

Can I get a replacement DB9 programming cable at your Sham Shui Po store?

Yes, we stock standard DB9 serial cables and USB-to-RS232 adapters at our Sham Shui Po retail shop to help you connect the PLC to modern laptops.

Full Product Description

High-Performance Industrial Automation

This FX1N-32MR compatible Programmable Logic Controller (PLC) is engineered for reliable industrial automation. Powered by a highly anti-interference 32-bit industrial MCU, its processing speed far exceeds the original FX1N series while remaining highly cost-effective. It is fully compatible with standard ladder logic programming using Mitsubishi GX Developer or GX Works2, allowing for seamless integration into existing workflows without the need to learn new software.

Versatile I/O and Connectivity

The board features 16 digital inputs (NPN/Low-level active) and 16 relay outputs, capable of driving up to 5A per relay, making it suitable for directly controlling intermediate relays, solenoid valves, and contactors. It includes a standard DB9 RS232 port for programming and HMI communication, and supports an optional RS485 interface (MODBUS RTU) for expanded network capabilities. The unit is housed in a protective DIN-rail mountable case with anti-corrosion, anti-moisture, and anti-static treatments.

Technician Tip

Always ensure you are using a strictly regulated DC24V power supply; connecting this PLC to AC power or 220V will instantly destroy the board. When connecting to a PC for programming, ensure your COM port baud rate is set correctly to 9.6K for the FX1N protocol. Our Sun Cheong Computer Co. Ltd. technical team reminds users that this board is sold blank; you must write or import your own ladder logic program before it will execute any machine commands.
