Bently Nevada 3500/93 135785-01 Machinery Protection Display Module

Product Description

The 3500/93 135785-01 from Bently Nevada is a rack-mounted operator display module developed for the 3500 Series Machinery Protection System. It provides direct, on-rack visualization of machinery condition data, allowing operators to monitor system status without relying on external HMIs or engineering workstations.

This module serves as a local interface for real-time diagnostics, presenting critical parameters such as vibration levels, rotational speed, temperature readings, and alarm states. It communicates internally with the system via the 3500/22M Transient Data Interface (TDI), ensuring synchronized and accurate data representation.

Functional Overview

The 3500/93 135785-01 enables on-site personnel to quickly assess machine health and system integrity. Key capabilities include:

• Continuous display of live process and condition monitoring data

• Immediate visualization of alarm and danger states

• Multiple viewing formats for different diagnostic needs

• Local interaction via integrated keypad controls

Display modes allow users to switch between summarized rack data and detailed channel-level information, supporting both routine monitoring and troubleshooting tasks.
