3500/94M-07-12-01 | Bently Nevada VGA Display Module - Petro Auto Tech

Product Overview

The 3500/94M-07-12-01 is a VGA Display Module from Bently Nevada, designed for industrial machinery monitoring systems. This module provides a clear visual interface for system data, status, and alarms, making it essential for operators in power generation, oil and gas, and manufacturing environments.

Technical Specifications Analysis

The 3500/94M-07-12-01 operates on a power consumption of 4.6 watts max and requires a +24 Vdc ± 6% input with a range of 22.5 to 25.5 Vdc. It includes a VGA port for analog red, green, blue, and sync signals, an RS232 port for touch controller data, and a front port for 24 Vdc power out, VGA signal out, and touch commands in. The module supports an operating temperature range of -20°C to 65°C (-22°F to 149°F) and storage temperature from -40°C to 85°C (-40°F to 185°F), with humidity tolerance up to 95% non-condensing. The monitor module requires 1 full-height front slot, and the I/O module needs 1 full-height rear slot in a rack.

Application Scenarios & Usage Methods

In a turbine monitoring system, the 3500/94M-07-12-01 displays real-time vibration and temperature data from Bently Nevada sensors, helping operators detect anomalies early. In a compressor control panel, it shows process values and alarm logs, enabling quick response to faults. For usage, connect the module to a 3500/22 Transient Data Interface (TDI) module via the high-speed network, and attach a compatible display (e.g., 15-inch Advantech FPM-8151) to the VGA port for visual output.

Installation Guide & Packing List

Install the monitor module in a 1 full-height front slot and the I/O module in a 1 full-height rear slot of a 3500 rack. Ensure the power supply provides +24 Vdc within 22.5 to 25.5 Vdc. Connect the VGA cable and RS232 cable as per the manual. The package typically includes the 3500/94M VGA Display Module (I/O module and monitor module), a display router box cable (20 ft/6 m), and mounting hardware. Verify all components before installation.

Purchasing Advice

When buying the 3500/94M-07-12-01, confirm compatibility with your existing 3500/22 TDI module and firmware versions (3500/94M Firmware 4.06 Rev. C or newer). This module is ideal for upgrading legacy systems or building new monitoring stations.

Repair & Maintenance Tips

Regularly inspect the module for dust accumulation on the VGA port and front port, cleaning with a dry cloth if needed. Keep the operating environment within -20°C to 65°C and humidity below 95% non-condensing. Check the OK LED for proper operation; if it fails, verify power input and connections. Store spare modules at -40°C to 85°C in a dry location.
