Equipped with LED indicators for power input, output status, and fault alerts, providing visual feedback to operators for quick troubleshooting of power-related issues.

Function

The primary function of the Bently Nevada 3500/91 161204-01 is to supply stable, regulated 24 VDC power to all connected modules within the 3500 Machinery Protection and Condition Monitoring System. It converts incoming AC or DC power from the plant grid into a clean, consistent output, ensuring that critical monitoring components (e.g., vibration monitors, temperature transmitters, communication gateways) receive uninterrupted power. By maintaining voltage stability and incorporating protective features, it prevents power-related disruptions that could compromise machinery health monitoring, enabling continuous data collection and real-time alerts.

Use

In industrial settings, the 3500/91 161204-01 serves as the “power backbone” of the 3500 system. It is installed in 3500 system racks, where it supplies power to modules responsible for monitoring equipment vibrations, temperatures, rotational speeds, and other critical parameters. For example, in a power plant, it powers vibration monitoring modules on a steam turbine, ensuring the system continuously tracks machinery health and triggers alarms if anomalies are detected. Its reliability is critical—any power failure could halt monitoring, increasing the risk of unplanned equipment downtime or catastrophic failures.

Application Fields
