Product Description

The 3500/93 (Part Number 135785-01) is a high-resolution Graphical LCD System Display designed for the Bently Nevada 3500 Machinery Protection System. This module provides localized visualization of critical asset condition data, allowing operators to monitor real-time machinery health without a separate workstation. With a 640 x 480 pixel resolution, the 135785-01 delivers clear, actionable information including system event lists, alarm logs, and all rack-resident data such as channel values, monitor statuses, relay states, and Keyphasor* tachometer readings.

Engineered for extreme industrial environments, the 3500/93 features an exceptionally wide operating temperature range from -40°C to +85°C, making it suitable for outdoor cabinets or high-heat processing areas. The display can be face-mounted directly onto the 3500 rack or remotely positioned for improved ergonomic access. By adhering to API 670 requirements, this display module ensures that safety-critical information is always available to maintenance personnel, facilitating rapid response to vibration anomalies or mechanical faults in turbines, compressors, and large-scale pump trains.

System Integration & Installation

The 135785-01 operates in conjunction with the 3500/93 Display Interface Module (DIM). For face-mount applications, the DIM must be installed in Slot 15 (the right-most slot) of the 3500 chassis to properly drive the display. Unlike the 3500/94, which utilizes a VGA output for larger external touchscreens, the 3500/93 (135785-01) provides a compact, ruggedized integrated viewing solution directly at the machinery protection rack. It is the preferred choice for petrochemical and power generation facilities requiring reliable, local situational awareness in harsh field conditions.

Frequently Asked Questions

Is the 135785-01 compatible with the 3500/94 VGA system?No. The 135785-01 is a proprietary LCD designed specifically for the 3500/93 system architecture. The 3500/94 uses standard VGA monitors and is a different hardware branch.

Can I mount this display several meters away from the rack?Yes. The 3500/93 system supports independent and panel mounting. However, ensure that the cable length between the DIM and the display remains within Bently Nevada's specified signal integrity limits for Ethernet/IP or proprietary links.
