Johnson Controls D-9502-5 Positioner

For technicians maintaining complex pneumatic logic, the Johnson Controls D-9502-5 serves as a high-precision relay for discrete positioning of damper actuators. This Pneumatic Damper Actuator Positioner is designed to interface seamlessly with D-3244, D-3246, and D-251 Number 5 Series Actuators, providing the dynamic stabilization necessary to overcome friction and high static pressure. Featuring a 2-12 PSI adjustable starting point and a 3-13 PSI adjustable operating span, the D-9502-5 allows for exacting sequential control and field calibration to meet specific system requirements. The unit is built with a rugged die-cast aluminum body and a Noryl cover, ensuring durability in mechanical rooms with ambient temperatures ranging from -20 to 150°F. Equipped with versatile 5/32" or 1/4" OD barb fitting air connections, this positioner facilitates easy integration into existing poly tubing lines. With a low air consumption of 5 SCIM and an output flow capacity of 1,000 SCIM, it ensures rapid response times and consistent performance across your HVACR control loops.

• Precise Actuator Control: Maintains exact damper positions by compensating for external forces and internal actuator friction.
• Field Adjustability: Independent starting point and operating span adjustments allow for customized staging and sequencing.
• Wide Compatibility: Direct-mount design specifically engineered for Johnson Controls D-3244 and D-3246 Series pneumatic actuators.
• Robust Construction: Die-cast aluminum housing and fabric-reinforced rubber diaphragms provide long-term reliability in demanding environments.
• Flexible Installation: Universal barbed fittings accommodate both 5/32" and 1/4" OD tubing for standard pneumatic infrastructure.

• Can this positioner be used for sequential operation? Yes, the 2-12 PSI adjustable starting point allows you to sequence multiple dampers from a single controller signal.
• Does the D-9502-5 require special mounting for D3246 actuators? While compatible, note that specific applications on D-3246 series may require a separate spring and pull arm (D-9502-100) for proper mechanical linkage.
• What is the maximum supply pressure? This unit is rated for a maximum supply air pressure of 25 PSIG, with recommended clean, dry, and oil-free air.
