Samson 4763-01200321000000.05 4763 Electropneumatic Positioner

The Samson 4763-01200321000000.05 is an electro-pneumatic valve positioner designed for precise control of pneumatic actuators in industrial processes. As part of the Samson 4763 series, it combines reliability, adaptability, and advanced functionality to meet the demands of various applications, particularly in harsh or complex environments.

Key Features and Functions

Signal Input & Compatibility

Accepts a standard 4–20 mA analog input signal for seamless integration with DCS (Distributed Control Systems) or PLC (Programmable Logic Controllers).

Built-in HART communication protocol enables digital communication for configuration, diagnostics, and remote monitoring, enhancing operational efficiency.

Precision Control Mechanism

Utilizes a piezoelectric valve with improved sealing technology to ensure stable air output and minimize air consumption, reducing operational costs.

Features an adjustable proportional band (P-band) to fine-tune control sensitivity, allowing customization for different process requirements.

Offers reversible action direction (direct or reverse), making it adaptable to various valve types (e.g., air-to-open or air-to-close).

Technical Specifications

Air Supply Pressure: 1.4–6 bar (20–90 psi).

Output Pressure Range: 0–6 bar (0–90 psi), compatible with most pneumatic actuators.

Temperature Range: Operates reliably in -40°C to +85°C (-40°F to +185°F), suitable for extreme industrial environments.

Protection Level: IP65-rated enclosure provides robust protection against dust and water jets.

Explosion Resistance: Certified for use in hazardous areas (e.g., ATEX, IECEx) with Ex ib IIC T6/T4 compliance, ensuring safety in explosive atmospheres.

Installation and Adaptability

Mounting Options:

Directly compatible with linear or rotary actuators via NAMUR flanges (VDI/VDE 3845 standard) or IEC 60534-6-1 rod-style brackets.

Can be integrated with Samson’s proprietary mounting systems for seamless alignment and reduced installation time.

Modular Design: Easy maintenance and calibration, with optional accessories like pressure gauges for monitoring supply and signal pressure.
