Q1: What is the primary function of the 125760-01?
It is a Data Manager I/O Module that acts as the primary communication and data management interface for the Bently Nevada 3500 monitoring system. It enables rack configuration, machinery data retrieval, and system integration with external communication processors.
Q2: Where should the 125760-01 be installed?
The module must be installed in Slot 1 of the 3500 rack, adjacent to the power supply modules. Only one RIM or Data Manager I/O Module is required per rack .
Q3: Is the 125760-01 part of the machinery protection path?
No. It performs rack-level communication and management functions but does not directly participate in the critical monitoring channel. The monitoring system's automatic machinery protection functions continue to operate normally even if this module is removed or fails.
Q4: Which communication processors are supported?
Compatible processors include TDXnet, TDIX, and DDIX communication interfaces. The module uses Bently Nevada's proprietary protocol for stable and efficient system communication .
Q5: Does the module support TMR systems?
Yes. In Triple Modular Redundant (TMR) systems, the specialized TMR RIM functionality (using the 125744-01 main card) provides monitor channel comparison and voting logic. The 125760-01 serves as the I/O interface in these configurations.
