Bently Nevada 3500/22 125768-01 Transient Data Interface Module

Bently Nevada 3500/22 125768-01 Transient Data Interface Module

Configured for transient waveform data acquisition and rack communication in the Bently Nevada 3500 monitoring system, the Bently Nevada 125768-01 (3500/22 Transient Data Interface Module) provides direct data collection and Ethernet communication functions between 3500 M-series monitor modules and compatible condition monitoring software platforms.

Hardware Specifications

Transient Data Acquisition and Ethernet Communication Interface

The 3500/22M Transient Data Interface combines the rack interface functions of the 3500/20 Rack Interface Module with communication processor capabilities for collecting machinery monitoring data. The module interfaces with M-series monitors such as 3500/40M and 3500/42M to acquire steady-state values and transient dynamic waveform data.

The TDI provides standard static data capture capability. When used with an optional Channel Enabling Disk, the module can collect dynamic and high-resolution transient data for diagnostic analysis. The integrated communication processor transfers collected data through an Ethernet connection to compatible host software.

The 3500/22 module operates outside the automatic machinery protection signal path. Although it provides rack-level communication and data handling functions, it does not affect normal monitor operation or protection logic execution. Each 3500 rack requires one TDI or RIM module installed in Slot 1 adjacent to the power supply modules.

Frequently Asked Questions

Q: Is the 3500/22 TDI part of the machinery protection monitoring path?
A: No. The TDI provides communication and data collection functions but is not part of the critical monitoring path used for automatic machinery protection.

Q: Where is the 125768-01 module installed in a 3500 rack?
A: The module is installed in Slot 1, directly adjacent to the power supply modules.

Q: What type of data can the TDI collect?
A: The TDI collects steady-state monitoring data as standard and can collect dynamic waveform and high-resolution transient data when configured with the required optional channel enabling function.

Field Installation Guidelines

• Install the 3500/22 module only in Slot 1 of the 3500 rack next to the power supply modules.
• Verify the rack contains only one TDI or RIM interface module as required by the system configuration.
• Connect Ethernet communication wiring according to the installed host software network requirements.
• Separate communication cables from high-voltage power wiring to reduce electrical interference.
• Verify 24 VDC supply wiring polarity before energizing the module.
• Confirm monitor module compatibility before enabling transient waveform data collection functions.
