The Bently Nevada 135785-02 3500/93 Display Unit is a back-lighted operator display interface designed for use with the 3500 machinery protection and condition monitoring system. The display unit provides graphical and text-based visualization of monitored machinery parameters, rack conditions, and alarm status information.
The display communicates with the Display Interface Module through an RS422 communication interface and supports both Bently Nevada proprietary protocol and Modbus protocol based on the AEG PI-MBUS300 Rev. E reference manual.
The display unit incorporates multiple status LEDs for rack condition indication and monitored channel status visualization. Alarm indicators provide visual notification for OK, Alert, and Danger operating states within the monitoring system.
The transflective FSTN dot matrix LCD includes a white electroluminescent backlight for visibility in low ambient light industrial environments. The unit is suitable for machinery monitoring systems installed in power generation, oil and gas, petrochemical, and industrial process facilities.
