Product Description

The SP377 Valve Positioner, also known as the SP377 SmartPositioner, is an advanced electropneumatic device designed to precisely control valve actuation in industrial automation systems. Equipped with dual analog/digital inputs and configurable outputs, it directly interfaces with process controllers and supports HART, PROFIBUS, or Foundation Fieldbus communication protocols. Operating within a 12-30V DC range and temperatures from -40°C to 85°C, it excels in harsh environments across oil & gas, chemical, and power generation industries. The SP377 Electropneumatic model features a compact 2.5-inch LCD interface for real-time diagnostics, 24-month battery backup for critical operations, and a sensing range of 0-100% valve travel. Key advantages include high linearity (±0.5%), dust/water resistance (IP66), and self-calibration, though installation requires proper pneumatic alignment. Its rugged aluminum housing ensures durability while maintaining precise stroke feedback detection up to 200 mm.
