As a trusted global supplier with over a decade of experience since 2011, Rossonix Co., Limited specializes in providing high-performance industrial automation components. We are proud to offer the genuine Foxboro SRD960-BHNDMN6EDZNC‑X1 Electro-pneumatic Positioner, a critical component for precise valve control in demanding process environments. This device translates a control signal into precise pneumatic pressure to accurately position control valves, ensuring optimal flow, pressure, and level regulation in your pipelines. Our commitment to quality, backed by ISO9001 certification, ensures you receive a reliable and durable solution that enhances your system's efficiency and reliability.
The Foxboro SRD960 positioner is engineered for exceptional accuracy and robust performance. Its core function is to receive an electrical control signal (typically 4-20 mA) and convert it into a proportional pneumatic output to drive a valve actuator, ensuring the valve reaches and maintains the exact position commanded by the control system.
Key Features and Technical Advantages:
High Precision & Repeatability: Advanced feedback mechanism and microprocessor control ensure precise valve positioning with minimal hysteresis, leading to consistent process control.
HART Communication Enabled: This model supports the HART protocol, allowing for digital configuration, calibration, diagnostics, and communication with asset management systems without interrupting the 4-20 mA signal.
Rugged Construction: Featuring an IP66/NEMA 4X enclosure rating, it is designed to withstand harsh industrial environments, including exposure to dust, moisture, and corrosive atmospheres.
Versatile Mounting & Actuation: Can be directly mounted to a wide range of linear and rotary valve actuators. It supports both single-acting (spring-return) and double-acting actuator configurations.
User-Friendly Interface: Local configuration and calibration are facilitated through an intuitive interface, reducing setup time and maintenance complexity.
Low Air Consumption: Efficient design minimizes instrument air usage, reducing operational costs associated with compressed air systems.
Technical Specifications:
| Parameter | Specification |
| Input Signal | 4-20 mA DC, two-wire, with HART |
| Air Supply Pressure Range | 1.4 to 7 bar (20 to 100 psi) |
| Output Pressure Range | 0 to 100% of supply pressure |
| Enclosure Protection | IP66 / NEMA 4X |
| Ambient Temperature Range | -40°C to +85°C (-40°F to +185°F) |
| Communication | HART Protocol (Bell 202 FSK) |
| Mounting | Direct to valve actuator (linear or rotary) |
Benefits for Your Operation:
Improved Process Control: Delivers precise and repeatable valve positioning, leading to tighter control over critical process variables like flow, pressure, and temperature.
Reduced Maintenance & Downtime: Robust design and diagnostic capabilities via HART help predict maintenance needs and troubleshoot issues quickly.
Enhanced Safety & Reliability: The rugged enclosure protects internal components, ensuring reliable operation in challenging conditions, which contributes to overall plant safety.
Integration Ease: Standard 4-20 mA input and HART protocol ensure seamless integration into existing DCS, PLC, or control system architectures.
Long-Term Cost Savings: High accuracy reduces product waste and energy consumption, while durability lowers total cost of ownership.

Frequently Asked Questions (FAQ)
What is the primary function of this electro-pneumatic positioner?
It converts a standard 4-20 mA electrical control signal into a proportional pneumatic output pressure to accurately position a valve's actuator, ensuring the valve opens or closes to the exact degree required by the process control system.Does this model support digital communication for setup and diagnostics?
Yes, the SRD960-BHNDMN6EDZNC‑X1 is equipped with HART protocol. This allows for digital configuration, calibration, and access to diagnostic information using a HART communicator or compatible software without disrupting the analog signal.What types of valves and actuators is this positioner compatible with?
It is designed for direct mounting on a wide array of linear (e.g., globe valve) and rotary (e.g., ball, butterfly valve) actuators from various manufacturers. It supports both single-acting (requiring air to one side) and double-acting (air to both sides) configurations.What is the significance of the IP66/NEMA 4X rating?
This rating indicates a high degree of protection. It is dust-tight (IP6x) and protected against powerful water jets (IPx6), making it suitable for outdoor installation and harsh industrial environments where exposure to moisture, dust, and corrosion is a concern.What is the required instrument air supply for this positioner?
The unit typically operates with a clean, dry air supply within a pressure range of 1.4 to 7 bar (approximately 20 to 100 psi). The specific required pressure may depend on the actuator it is controlling.Can this positioner be used in safety instrumented functions (SIF)?
While it is a highly reliable and accurate device, its suitability for a specific Safety Integrity Level (SIL) rated loop must be evaluated as part of a full safety instrumented system (SIS) design by a qualified engineer, considering all components and the required risk reduction.How do I calibrate the Foxboro SRD960 positioner?
Calibration can be performed locally using the manual buttons and display on the device or remotely via the HART communication channel using dedicated configuration tools, following the procedures outlined in the official product manual.What are the main application industries for this product?
It is widely used in industries requiring precise fluid control, including oil & gas production and refining, chemical processing, power generation (thermal, nuclear), water and wastewater treatment, pharmaceuticals, and food & beverage.
