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 enabled, the program cannot be read without the correct password. It delivers stable and reliable performance, with a built-in watchdog circuit to ensure continuous, 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 in) Color: As shown Material: PC + Plastic Notes: 1. A USB-TTL adapter is required when connecting the PLC to a computer for programming with GX software. 2. The PLC includes one built-in analog input (AD0) with a 0–10 V input range. 3. The PLC includes one built-in analog input (AD1) with a 0–10 V input range. 4. Connecting the PLC to a touchscreen 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 screen settings. Dimensional tolerance: ±1–3 cm.
