Bray 6A6DR50200NN005KA0 Series 6A Electro-Pneumatic Positioner 4-20mA Double Acting

The Bray 6A6DR50200NN005KA0 is a Series 6A electro-pneumatic positioner designed for precise control of double-acting pneumatic actuators in modulating service applications. This intelligent positioner provides reliable control over final control elements across a broad range of process industries, featuring advanced diagnostics and adaptive control capabilities.

Key Features:

• 4-20mA analog input signal with 2-watt power consumption for efficient operation
• Online adaptive control continuously optimizes control behavior and travel times in response to changing line pressure conditions
• Industry-leading low air consumption rate of 0.0059 SCFM, reducing compressor energy costs and CO2 emissions
• Auto-calibration system completes setup in less than 5 minutes using simple keypad push buttons
• LCD display provides visual confirmation of valve position in precise one-degree increments
• Integrated diagnostics with corrective and preventative maintenance self-checks that run constantly
• Air supply monitor transmits fault signal alarm if air supply fails, shown locally and remotely
• Friction clutch locking device for high-vibration applications
• Available in three fail-safe modes: Fail-Safe, Fail-in-Place, and Fail-Open

Technical Specifications:

• Supply Pressure: 20-102 PSI (1.4-7 Bar)
• Temperature Range: -22°F to +176°F (-30°C to +80°C)
• Connections: 1/4" NPT (G 1/4")
• Protection Class: NEMA 4, 4X and IP66
• Housing: Waterproof fiberglass reinforced polymer with metalized coating for EMC protection
• Mounting Standard: VDI/VDE 3845 (NAMUR)

This positioner is compatible with Bray Series 92-119 and Series 92-128 pneumatic actuators when used with the appropriate mounting kit (6A1180-24610536, sold separately). The unit features internal flow restrictors for precise control even with small actuators, and includes both LCD display and yellow visual position indicator for at-a-distance monitoring.
