This programmable logic controller uses an industrial-grade 32-bit MCU with strong anti-interference capability and high processing speed. The PLC board is compatible with GX programming software for ladder diagram programming and supports direct download and online monitoring. It features password protection; once a password is set, the program cannot be read. It delivers stable and reliable performance, with a built-in watchdog circuit to ensure long-term operation. It is widely used in industrial automation applications, including metallurgy, chemical processing, plastics, textiles, food, packaging, printing, building materials, woodworking, HVAC systems, environmental equipment, and single-process control in assembly lines and machine tools. Voltage: 10–28 VDC Rated current: 5 A Dimensions: 7.2 × 3.5 cm (2.83 × 1.38 inches) Color: As shown Material: PC + plastic Notes: 1. A USB-TTL adapter board is required to connect the PLC to a computer when using GX programming software. 2. The PLC has one built-in analog input (AD0) with a voltage range of 0–10 V. 3. The PLC has one built-in analog input (AD1) with a voltage range of 0–10 V. 4. Connecting the PLC to a touch screen or text display requires an external RS232-to-TTL module. Slight variations in appearance may occur between production batches; these do not affect functionality. Package contents: 1 × PLC industrial control board 1 × programming cable Note: Color representation may vary slightly due to lighting conditions and display settings. Dimensional tolerance: ±1–3 cm.
