Bently 3500/20 is the Rack Interface Module (RIM) of the Bently Nevada 3500 series. It is the core communication component of the 3500 vibration monitoring system and must be installed at Slot 1 of the rack (adjacent to the power module).

The module supports proprietary protocols for configuring racks and obtaining mechanical vibration data, and interacts with external communication processors such as TDXnet, TDIX, DDIX.

Provide system access (such as Trip Multiply, Alarm Inhibit, Rack Reset), support RS232/RS422 serial communication, facilitate host software connection and data acquisition.

The front panel includes a reset button, address switches (up to 63 addresses), and a configuration key lock (RUN/GRAM mode).

Power supply: 18-36 VDC, power consumption of approximately 4.75W, transducer power supply of 24 VDC.

Communication: RS232 (front board, 38.4 kbaud, cable length 30m); RS422 (I/O module, 1200m); Internal modem 14.4 kbaud.

Environment: -30 ° C to+65 ° C, size approximately 10.2 × 11.4 × 13.2 cm, weight 0.5 kg.

LED indicators: OK, TX/RX, TM (Trip Multiply), CONFIG OK.

Specially designed for 3500 system racks (such as 3500/05 series), tightly integrated with monitor modules (such as 3500/40M 125680-01) and power modules, supporting System 1 condition monitoring (specific backplane required).

Commonly used for rotating equipment such as turbines and generators, providing real-time protection and data interfaces.

The English name for SCSI is "Small Computer System Interface", which is translated as "Small Computer System Specific Interface" in Chinese; As the name suggests, this is an expansion interface designed for small computers, which allows computers to install other peripheral devices to improve system performance or add new features, such as hard drives, optical drives, scanners, etc.

Early computers were classified into various levels based on speed and functionality, including mainframes, small computers, and microcomputers. Some small workstations and servers were classified as small computers, while personal computers were classified as microcomputers; Therefore, at that time, the models that used SCSI interfaces were mainly mid to high end devices such as workstations and servers. In recent years, due to the significant increase in personal computer performance and expansion requirements, the application of SCSI in PCs (ordinary microcomputers) has also been increasing.

In fact, SCSI is not a new interface type. It has been almost 20 years since someone noticed the issue of extending the functionality of small computers, started developing new unified expansion interfaces, and officially established the SCSI standard in 1986. In the early days, Apple was the first to select SCSI as the standard interface for Macs computers, and many peripherals were connected to the main system through this unified interface. On the PC side, SCSI interface cards and devices are expensive, and almost all peripherals have cheaper interfaces to replace them, so SCSI is not favored; On the other hand, there are not many available SCSI devices. On the other hand, today's peripheral products that support SCSI interface have expanded from only hard drives and tape drives to various devices such as scanners, optical drives, burners, MOs, etc. The opportunities for people to come into contact with SCSI are gradually increasing; In addition, with the advancement of manufacturing technology, the prices of SCSI cards and peripherals are no longer high, indicating that the SCSI market has become quite mature.
