Product Description

The SM-302F-PA20 integrates the SM302F sensor module and PA20 signal converter, designed for robust industrial applications including manufacturing, automation, and process control. The SM302F sensor module features dual 4-20mA analog inputs and two configurable switch outputs, supporting direct connection to up to three auxiliary modules. It operates on 12-24V DC with a wide temperature tolerance (-20°C to 60°C). The PA20 signal converter enables seamless RS-485 communication with Modbus protocol compatibility. Key specifications include a 0-30m detection range, compact 2.5-inch display, and integrated 2000mAh backup battery. Advantages include high-precision sensing, rugged construction, and plug-and-play installation, though its limited screen size may require external interfaces for detailed data visualization. This system excels in harsh environments while maintaining reliable signal conversion and modular scalability.
