Bently Nevada 3500/20

Key Features

Communication Bridge: Bently Nevada 3500/20 acts as a crucial communication conduit, supporting a proprietary protocol for configuring the rack and retrieving machinery data accurately and securely. This allows for seamless data exchange between the machinery and the control system.

Strategic Positioning: The module must be placed in the first slot of the rack (next to the power supplies). This strategic placement ensures stable and efficient communication with other components within the rack.

External Communication Processor Compatibility: Bently Nevada 3500/20 is compatible with Bently Nevada's external communication processors such as Tdxnet, Tdix, and Ddix, enhancing the system's flexibility and expandability. This enables the connection of the 3500 system to a wider range of external devices and systems.

Non-Intrusive in Monitoring Path: Although Bently Nevada 3500/20 provides certain common functions for the entire rack, it is not part of the critical monitoring path. This means that its presence does not affect the overall operation and monitoring efficiency of the system. Instead, it acts as an intelligent coordinator, enhancing the accessibility of data retrieval.

Redundancy Option for High Reliability: For applications demanding high levels of redundancy and reliability, a TMR (Triple Modular Redundant) version is available. This version features a "monitor channel comparison" function, which continuously compares the outputs of three redundant monitors to improve the system's reliability and safety.

Technical Specifications

Power Consumption: It has a typical power consumption of 4.75 watts.

Communication Interfaces: The front panel has an RS-232 serial interface with a maximum baud rate of 38.4k. The cable length for this interface is up to 30 meters.

The I/O (Input/Output) module has RS-232/RS-422 serial interfaces, also with a maximum baud rate of 38.4k. The cable length for the RS-232 interface is up to 30 meters, and for the RS-422 interface, it is up to 1200 meters.

LED Indicators:The OK LED flashes when the module is operating normally. The TX/RX LED flashes when the module is communicating with other modules in the 3500 rack. The TM LED flashes when the 3500 rack is in the alarm multiplication state. The Config OK LED flashes when the configuration of the 3500 rack is correct.

Environmental Adaptability: The module can operate within a temperature range of -30°C to 65°C (-22°F to 149°F), enabling it to adapt to various industrial environments.
