Product Description

The SM-306U-PA651 module is a high-performance signal isolator converter designed for PA651 process automation systems. It features 2-channel universal inputs (supports 4-20mA, 0-10V, thermocouples) and 1 isolated 4-20mA output, enabling direct connection to up to 4 expansion modules. Equipped with RS-485 Modbus communication and HART protocol support, it operates within 12-36V DC and -20°C to +60°C. Widely used in chemical, oil/gas, and water treatment industries, its key advantages include 0.1% precision, galvanic isolation, and rugged construction. Limited to wired connectivity and no built-in display, it compensates with a compact 85x40x25mm design. The module integrates surge protection for harsh environments and offers a 3000V isolation barrier, ensuring reliable signal transmission across sensor distances up to 500 meters.
