Our commitment, backed by ISO9001 certification, is to deliver components that enhance process efficiency and minimize downtime for our partners across diverse markets from North America to Oceania.
The SRD960-BHNDMN6BDZNC-X1 is a microprocessor-based smart positioner designed to precisely control the position of a valve actuator based on an electrical input signal. It translates standard control signals into proportional pneumatic output, enabling automated, precise, and responsive flow control in demanding industrial environments.
Core Features & Technical Advantages:
High Precision Control: Incorporates advanced non-contact sensing technology and a high-gain pilot valve for exceptional positioning accuracy and repeatability, typically within ±0.5% of span, ensuring consistent process parameters.
Robust Communication & Diagnostics: Native support for the HART communication protocol allows for easy configuration, calibration, and remote diagnostics using standard handheld communicators or asset management software, facilitating predictive maintenance.
Superior Environmental Protection: The housing is rated IP66/67 and NEMA 4X, making it resistant to dust ingress and powerful water jets. It is engineered to perform reliably in harsh conditions, from freezing cold to high temperatures.
Wide Compatibility & Flexible Mounting: Designed for direct mounting on a vast range of linear and part-turn rotary actuators from major manufacturers. Its universal mounting kit simplifies installation and reduces inventory needs.
Low Air Consumption: Features an efficient spool valve design that minimizes instrument air consumption during steady-state operation, leading to significant energy savings in compressed air systems over time.
User-Friendly Interface: Equipped with a local push-button interface and a clear LCD display for on-site configuration, status indication, and troubleshooting without the need for external tools.

Frequently Asked Questions (FAQ):
Q: Can this positioner be used on both linear and rotary valve actuators?
A: Yes, absolutely. The SRD960-BHNDMN6BDZNC-X1 is designed with universal mounting capabilities. It comes with adaptable mounting kits that allow for straightforward installation on most linear (stem-type) and part-turn rotary actuators available on the market.Q: What is the benefit of having HART protocol on a positioner?
A: HART protocol enables two-way digital communication over the standard 4-20mA wiring. This allows for remote configuration, calibration, and access to valuable diagnostic information (like valve travel, supply pressure, etc.) without needing to visit the valve in the field, saving significant time and labor for maintenance teams.Q: Is the device suitable for use in hazardous areas?
A: The standard model is built with a robust IP66/67 and NEMA 4X enclosure for general harsh environments. For installations requiring certification for specific hazardous area classifications (like ATEX or IECEx), please inquire with our sales team for available options or compatible models.Q: How do I configure the positioner after installation?
A: Configuration can be done easily in three ways: using the local push buttons and LCD display on the device, with a standard HART handheld communicator, or via asset management software on your control system if it supports HART integration. An auto-calibration function simplifies the initial setup.Q: What is the expected air supply quality for optimal operation?
A: For reliable and long-lasting performance, we recommend using clean, dry instrument air according to ISA 7.0.01 quality standard (e.g., dew point at least 10°C below ambient temperature, particle sizeQ: Do you offer different communication protocols besides HART?
A: Yes. While HART is the standard and most common protocol, the SRD960 platform can be optionally configured to support other major fieldbus protocols such as PROFIBUS PA and Foundation Fieldbus (FF). Please specify your requirement when ordering.Q: What is the typical lead time for this product?
A: As a trading company with established supply chains, we generally maintain stock for popular models. Lead times can vary based on specific configuration and order quantity. We strive to provide accurate delivery estimates upon inquiry to ensure your project planning proceeds smoothly.Q: Can you provide technical support or documentation?
A: Certainly. We provide comprehensive product manuals, datasheets, and mounting instructions. Our technical team is also available to assist with integration queries and application suitability to ensure you get the right solution for your needs.
