Product Performance

The module adopts a dual-protocol processor parallel architecture, with protocol conversion response time ≤8ms, which can synchronize all monitoring data in the 3500 frame in real time (including vibration peak-to-peak, shaft displacement, differential expansion, bearing temperature, equipment status word), and data transmission delay ≤50ms to ensure the real-time performance of remote monitoring. It supports custom data acquisition cycles (100ms-10s adjustable) and data filtering rules, transmitting only valid monitoring data, reducing network bandwidth usage by ≥30%.

It has Ethernet link redundancy and data path redundancy. When the main link fails, it automatically switches to the backup link with switching time ≤30ms; combined with the local data breakpoint resume mechanism, it can recover all monitoring data during the link interruption period to ensure no data loss. Integrated with a full-link self-test system, it real-time monitors the status of communication interfaces, protocol stacks, power supply circuits, and frame bus connections, with fault diagnosis coverage ≥99.5%. Fault information is fed back through three channels: LED indicators, system bus, and external alarm terminals, facilitating quick problem location.

Fully compatible with Bently Nevada System 1® equipment health management software and third-party DCS (Siemens PCS 7, Rockwell PlantPAx, Emerson DeltaV), it supports online configuration of communication parameters, protocol mapping, and redundancy strategies through a web interface or System 1® software, with no shutdown required for configuration updates. The mean time between failures (MTBF) is ≥500,000 hours, meeting the 24/7 continuous operation needs of industrial scenarios.
