18745-03 Bently Nevada 3500 Communication Gateway Module 24 VDC IP20 2×RJ45

18745-03 Bently Nevada 3500 Communication Gateway Module 24 VDC IP20 2×RJ45

I. Product Overview
The 18745-03 is a dedicated communication gateway module for the 3500 series from Bently Nevada. It converts real-time vibration, displacement, and temperature signals within the machine frame into common protocols such as Modbus/TCP and Ethernet/IP, enabling seamless integration into DCS, SCADA, or PLCs. This single module enables high-speed, two-way data exchange between the 3500 system and the upper layers of the Industrial Internet, serving as the core gateway for remote diagnostics and predictive maintenance in smart factories.

II. Core Selling Points
- Open Protocol: Supports Modbus/TCP, Ethernet/IP, and OPC-UA, requiring no secondary development
- Plug-and-Play: Directly connects to the 3500 rack via the backplane, automatically identifies I/O modules, and enables zero-configuration online deployment
- Data Integrity: Parallel output of over 50 tags, including raw waveforms, total vibration values, alarm status, and speed
- Millisecond Refresh: Minimum 100 ms cycle time meets the transient capture requirements of turbomachinery
- Industrial-grade wide operating temperature range: -40°C to +70°C for long-term operation, and CE/FCC Class A electromagnetic interference resistance
