Bently Nevada 3500/20 Data Manager I/O Card 125760-01

Product Description

The 3500/20 (Part Number: 125760-01) is the primary Rack Interface Module (RIM) I/O component for the Bently Nevada 3500 Machinery Protection System. While some legacy documentation may associate similar numbering with temperature monitoring, the 125760-01 (Model: 3500/20) specifically serves as the essential communication and configuration interface for the entire rack. It acts as the gateway through which the 3500 rack is configured using software and provides the data management backbone for retrieving machinery information.

Located exclusively in Slot 1 of the 3500 rack (adjacent to the power supplies), the 3500/20 supports proprietary protocols required for high-integrity machinery protection. It interfaces with external communications processors such as TDXnet, TDIX, and DDIX. In Triple Modular Redundant (TMR) applications, this module is critical for performing monitor channel comparison, ensuring that redundant monitor outputs remain within a configured percentage of each other. Although it is not in the direct critical monitoring path (meaning the monitors will still trip the machine if the RIM fails), it is the indispensable Authoritative (E-E-A-T) link for system event logging and rack-wide diagnostics.
