Tag:

Technical Specifications Supply: 24 V DC ±10%; communication: DeviceNet 2.0A/B; flow range: 0–45 kg/h natural gas; operating pressure: 0.5–10 bar(g); operating temperature: -30 °C to +120 °C; enclosure: IP65; position resolution: 12-bit.

Functional Features DeviceNet fieldbus interface; closed-loop position control; remote configuration; fault diagnostics; flow metering; electronic nameplate.

Application Scenarios DeviceNet engine control systems, distributed plant automation, networked gas engine management, smart factory fuel control.

Performance Parameters Flow accuracy: ±2% FS; communication update rate: 20 ms; position resolution: 12-bit; fault response time: < 100 ms.

Material Composition Aluminum valve body; stainless steel internals; position sensor; DeviceNet controller; solenoid assembly.

Structural Characteristics In-line flow body; top-mounted electronics and solenoid; DeviceNet connector; threaded process connections.

Working Principle On-board DeviceNet interface receives flow commands from the network master, executes closed-loop position control via internal position feedback, and reports valve status and diagnostics back over the bus.

Installation Requirements Install inline with flow direction; connect DeviceNet trunk cable; set MAC ID and baud rate; calibrate during commissioning.
