Product Description

The Fisher 9956L positioner, a key component of the DVC6000 series valve controller family, is a high-performance pneumatic valve positioner designed for precise valve actuation. It features a 4-20 mA analog input, a pneumatic output (3-15 psi or 0.2-1.0 bar), and direct integration with Fieldbus or HART communication protocols for real-time data exchange. Operating within 12-30V DC and a temperature range of -40°C to +85°C, it is widely used in oil & gas, chemical, and power industries. The device includes a 2.5-inch LCD display for configuration, supports valve strokes up to 100 mm, and offers IP66/IP67-rated ruggedness for harsh environments. Advantages include exceptional linearity (±0.5% span) and diagnostics, while its relative complexity may require specialized calibration. No onboard battery is required due to loop-powered operation.
