StoneL Quartz QX92 DeviceNet Valve Communication Terminal
The StoneL Quartz QX92 DeviceNet Valve Communication Terminal is an industrial valve communication and control device designed to integrate automated on/off valves with DeviceNet networks. As part of the StoneL Quartz QX series, it combines valve position feedback, network communication and solenoid output control in one compact field-mounted assembly.
Instead of treating valve monitoring and solenoid control as separate network devices, the QX92 platform brings essential valve automation signals together. This arrangement can simplify system integration and help maintenance teams obtain useful information from remote valve installations. Furthermore, the Quartz enclosure platform is designed for challenging process environments where dependable field equipment is important.

How the QX92 DeviceNet Terminal Works
The QX92 connects valve position information and control outputs to a DeviceNet network. Its discrete inputs represent valve position sensing, while its outputs support compatible solenoid control functions. The additional analog input can communicate a 4–20 mA measurement when an appropriate external transmitter is used. As a result, several useful signals can be integrated into a single valve communication device.
The communication module supports polling, cyclic messaging and change-of-state communication. Network parameters, including baud rate and node address, must match the connected control architecture. Because DeviceNet systems can include different hardware revisions and configuration files, buyers should confirm the applicable module revision when replacing an existing unit.
Valmet provides DeviceNet design tools and EDS files for StoneL communication terminals. Selecting the appropriate revision can help engineering teams identify the correct device profile for their existing automation project.
Industrial Applications
The StoneL Quartz QX92 is relevant to industrial process installations that use automated valves and DeviceNet-based communication. Typical application sectors include oil and gas processing, petrochemical plants, chemical manufacturing, pulp and paper facilities, power generation, water treatment and general manufacturing operations.
In these environments, valve position confirmation and communication with the control system are important for operational visibility. For example, an automated process valve may need to report its open or closed position while receiving a control command through the network. The QX92 platform is designed to support this type of integrated valve automation architecture.
Nevertheless, suitability depends on the specific actuator, electrical load, communication configuration and site requirements. Where hazardous-area approvals are necessary, the complete product certification and applicable installation instructions must be checked.
QX92 DeviceNet vs. QX96 AS-Interface
The StoneL Quartz QX92 and QX96 both belong to the Quartz valve communication family, but they use different industrial network protocols. The QX92 is intended for DeviceNet systems, whereas the QX96 is intended for AS-Interface networks. Although both series provide valve automation communication functions, their network interfaces are not interchangeable.
Therefore, replacement selection should begin with the existing control system protocol. A customer using a DeviceNet network should verify the QX92 ordering code rather than selecting another Quartz communication terminal based only on similar enclosure appearance.
Ordering and Replacement Guidance
Before requesting a replacement, check the original nameplate for the complete model number. In addition, record the network configuration, existing device revision, conduit or connector requirements and any applicable hazardous-area approvals. Photographs of the original unit and its packaging can also help identify the required configuration.
When replacing an older StoneL Quartz QX92 terminal, the correct DeviceNet EDS file and firmware or hardware revision may be relevant to compatibility. Consequently, it is advisable to provide this information when available. Complete identification can reduce purchasing errors and unnecessary downtime.
