StoneL Quartz QX97 AS-Interface Extended Addressing Valve Communication Terminal
The StoneL Quartz QX97 AS-Interface Extended Addressing Valve Communication Terminal is designed to connect automated on/off valves to industrial AS-Interface networks. As part of the StoneL Quartz QX product family, the QX97 combines valve position sensing, auxiliary discrete inputs and solenoid output control in a compact field-mounted communication terminal.
The QX97 supports AS-Interface extended addressing, allowing up to 62 appropriately addressed devices on a compatible network. This makes the product relevant to process automation systems where multiple valve assemblies need to exchange discrete feedback and control signals with an AS-i master. Its integrated design helps organize field communication while retaining the rugged enclosure characteristics of the Quartz platform.
Wuhan Yuli Automation supplies quotation support for QX97E02NRA, QX97E03NRA, QX97R05NRA and QX97R06NRA. Customers should identify the complete ordering code before requesting replacement equipment because mechanical connections, indication arrangements and approvals can differ between configurations.

How AS-Interface Extended Addressing Works
AS-Interface is an industrial communication system used to connect field-level sensors and actuators. The StoneL QX97 communicates through an AS-i network and provides the valve-related signals needed by a compatible control system. Two sensor inputs can indicate the end positions of an automated valve, while two auxiliary inputs accommodate additional discrete information.
The extended addressing feature enables a compatible AS-i network to accommodate up to 62 addressed devices. Compared with standard addressing, this can offer greater flexibility when designing systems with numerous automated valves. However, actual network capacity and compatibility depend on the AS-i master, addressing arrangement, power budget and other connected devices.
The QX97 also provides one output for a compatible solenoid circuit. This output must remain within the manufacturer’s voltage, current and power limits. Therefore, electrical specifications should be reviewed carefully when selecting a replacement terminal or planning a new installation.
Industrial Applications
The StoneL Quartz QX97 is suitable for consideration in industrial valve automation projects that use AS-Interface communication. Common application sectors include oil and gas, petrochemical processing, chemical manufacturing, power generation, water and wastewater treatment, pulp and paper, and other process industries.
For example, a processing facility may operate many automated on/off valves across production equipment. Valve position feedback helps the control system confirm whether each valve has reached the expected open or closed position. The integrated communication terminal can then transfer the relevant information through a compatible AS-i network.
In addition, auxiliary inputs can provide additional field information when supported by the application. The actual installation must consider actuator compatibility, mounting arrangements, wiring requirements and any applicable safety or hazardous-location approvals.
StoneL Quartz QX97 vs. QX96
The QX96 and QX97 are both AS-Interface valve communication terminals, but their standard network addressing and output configurations differ. The QX96 supports standard addressing for up to 31 devices and provides two solenoid outputs. By comparison, the QX97 supports extended addressing for up to 62 devices and provides one solenoid output in the documented Quartz configuration.
Therefore, these series should not be treated as direct substitutes. When replacing a QX96 with a QX97, or vice versa, the control system, AS-i master, output requirements and full ordering codes must be checked. Choosing the correct communication module is essential for reliable integration with existing industrial automation equipment.
Ordering and Replacement Guidance
Before ordering a StoneL Quartz QX97, check the complete model number on the existing device nameplate. Customers should also confirm the AS-i communication configuration, mounting interface, electrical connections, visual indicator and any required certification markings.
For replacement projects, photographs of the original unit can help identify its physical configuration. Providing the existing AS-i network information may also help clarify whether the required device uses extended addressing. When different models appear similar, it is important to verify compatibility rather than relying on enclosure appearance alone.
