StoneL Quartz QN97 AS-i Extended Addressing VCT QN97C02NRA QN97C03NRA QN97D05NRA QN97D06NRA

StoneL QN97C02NRA is a Quartz AS-i Extended Addressing Valve Communication Terminal (VCT) associated with industrial on/off valve monitoring and field-level communication. This WooCommerce product includes four ordering references: QN97C02NRA, QN97C03NRA, QN97D05NRA and QN97D06NRA. Customers can select the exact reference required for an existing installation, replacement project or compatible valve automation system.

The StoneL Quartz QN97 family uses the AS-Interface communication concept with extended addressing. This feature helps compatible networks accommodate more addressed field devices than conventional AS-i arrangements. However, actual system capacity depends on the AS-i master, addressing configuration and other connected equipment.

Industrial process plants depend on automated valves to manage fluid flow, isolate equipment and coordinate production operations. In many installations, the control system needs information about valve position and equipment status. A valve communication terminal provides an interface between compatible valve-mounted components and an industrial field communication network.

The Quartz platform includes several sensing and communication configurations. StoneL identifies function code 97 as an AS-Interface Valve Communication Terminal with extended addressing. This distinguishes the QN97 family from conventional QN96 AS-Interface configurations and QN92 DeviceNet products.

AS-i extended addressing uses a compatible addressing arrangement to accommodate additional devices on the same network. Valmet’s technical documentation identifies support for up to 62 devices per network for the extended-addressing function. Nevertheless, this is a network capability rather than a guarantee that every existing system can accept additional equipment without changes.

For purchasing and maintenance, the complete ordering reference remains important. Two QN97 terminals may share the same communication family while having different mechanical or electrical configurations. Therefore, buyers should compare the original nameplate, installation requirements and manufacturer ordering information.

Available StoneL Quartz QN97 Models

Four complete QN97 ordering references are included in this variable product. Each variation should have its own SKU in WooCommerce. The descriptions below identify the family and ordering configuration without assigning unverified specifications to individual models.

Model Verification Notice: The exact meaning of the C02, C03, D05 and D06 suffixes must be confirmed using the manufacturer’s applicable ordering guide. Do not assume that these variations are electrically or mechanically interchangeable.

Features and Functions of the QN97 Series

AS-Interface Extended Addressing

Extended addressing is the defining communication characteristic of the QN97 function family. In a compatible AS-i system, the addressing method allows more field devices to be represented on the network. This can be useful in automation architectures containing numerous discrete sensors and actuators.

Valmet’s Quartz technical literature identifies the extended-addressing function as an AS-i version 3.0 configuration supporting up to 62 devices per network. Network design, master compatibility and device profiles should still be verified for the specific installation.

Valve Status Communication

A valve communication terminal helps connect valve-related information to a compatible automation network. This may support monitoring of open and closed positions and coordination of connected valve equipment.

Actual signal availability depends on the selected terminal and its installed configuration. The complete manufacturer’s documentation should be consulted before assigning specific input or output functions to an individual ordering code.

Quartz Industrial Enclosure Platform

The StoneL Quartz product family provides valve-mounted monitoring and communication solutions for industrial environments. Different enclosure and indication configurations are available within the wider platform.

Enclosure protection, material selection, temperature ratings and hazardous-location approvals must be checked for the complete model. A family-level description does not establish that every ordering variation carries the same approval.

Replacement and Maintenance Applications

Existing industrial plants often require replacement components that match established field communication systems. Selecting the exact StoneL reference helps purchasing teams communicate their requirements clearly.

For example, QN97C02NRA and QN97C03NRA should be checked against their original configuration records. Likewise, QN97D05NRA and QN97D06NRA require individual verification before substitution.

Industrial Applications

StoneL Quartz QN97 terminals may be relevant to compatible AS-Interface valve automation installations across process industries. Final suitability depends on the network architecture, valve assembly and environmental requirements.

• Oil and Gas: Valve status communication in compatible field networks.
• Petrochemical: Monitoring of automated on/off valves.
• Chemical Processing: Field-level communication for process valve assemblies.
• Power Generation: Valve monitoring in auxiliary systems.
• Water Treatment: Network integration of automated valves.
• Pulp and Paper: Communication with compatible valve equipment.
• Industrial Utilities: Maintenance of existing AS-i installations.

For applications with hazardous-location requirements, buyers should review the exact equipment markings and installation instructions. Approval requirements cannot be determined from the model family name alone.

How to Select the Correct StoneL QN97 Model

Step 1: Identify the full part number. Record every character from the original product nameplate. The complete reference is necessary for accurate replacement identification.

Step 2: Confirm the AS-i addressing arrangement. Verify that the control network supports the extended-addressing configuration required by the QN97 family.

Step 3: Check network compatibility. Review the installed AS-i master or gateway, addressing method, device profile and network power arrangement.

Step 4: Compare mechanical connections. Confirm the mounting interface, conduit entries, wiring arrangement and available installation space.

Step 5: Review site conditions. Verify environmental limits, enclosure requirements and any necessary certifications using the manufacturer’s applicable documents.

Step 6: Request commercial confirmation. Provide the exact model, required quantity, delivery destination and project schedule when contacting a supplier.
