Product Description

Overview

The Bently Nevada 286566-01 is a high-precision HART I/O Module for the 3500/62 Process Variable Monitor, part of the Bently Nevada 3500 Machinery Protection System. This 6-channel module enables simultaneous analog monitoring and digital communication, allowing operators to read primary process variables, diagnostic information, and device status from HART-enabled field instruments.

By combining analog and digital data acquisition, the 286566-01 enhances condition monitoring, reduces unnecessary downtime, and provides actionable insights for critical rotating machinery, including turbines, compressors, and pumps.

Key Features

• Six independent analog channels for 4–20 mA signals

• Full HART protocol support (versions 5, 6, 7) for device diagnostics and configuration

• Internal termination simplifies cabinet wiring and reduces installation complexity

• Galvanic isolation between channels and from the system backplane for fault protection

• Precision 16-bit A/D conversion for high-resolution process monitoring

• Hot-swappable design for continuous operation without rack shutdown

• Rugged industrial construction with EMI resistance and wide temperature tolerance

• Power consumption under 5 Watts, minimizing rack load

Technical Specifications

Applications

• Monitoring pressure, temperature, and flow for high-speed machinery

• Integrating smart transmitters into Bently Nevada 3500 systems

• Real-time device health tracking to prevent false alarms

• Critical plant operations where distinguishing between process alarms and instrumentation faults is essential

• Industrial facilities including power generation, petrochemical, and turbine-driven equipment

FAQ
