描述
一、产品概述
BENTLY 3500/20 125768-01是本特利（Bently Nevada）3500监测系统的核心接口模块（RIM，Rack Interface Module），用于框架组态、数据采集及通信管理。该模块必须安装在框架的第一个插槽（紧邻电源模块），支持RS-232/RS-422通信协议，兼容TDXnet、TDIX等外部通信处理器，是3500系统运行的基础组件。其TMR（三重模块冗余）版本还具备通道比较功能，确保高可靠性监测。
二、核心功能与技术特性
1.核心功能
框架组态与数据交互：
支持Bently专有协议，通过RS-232/RS-422接口与上位机或外部处理器通信，波特率最高38.4K（自动调节）。
提供菊花链连接功能，支持多框架级联，扩展系统规模。
冗余监测（TMR版本）：
持续比较三个冗余监测器的输出数据，若任一通道偏离设定百分比范围，标记故障并触发系统事件列表报警。
状态监控与控制：
前面板LED指示模块运行状态（OK、TX/RX、TM、CONFIG OK），支持框架复位、地址设置及组态模式切换（RUN/PROGRAM）。
2.技术参数

1.Product Overview
BENTLY 3500/20 125768-01 is the core interface module(RIM)of the Bently Nevada 3500 monitoring system,used for framework configuration,data acquisition and communication management.This module must be installed in the first slot of the frame(close to the power module),supports RS-232/RS-422 communication protocol,is compatible with external communication processors such as TDXnet and TDIX,and is the basic component for the operation of the 3500 system.Its TMR(Triple Module Redundancy)version also has channel comparison function to ensure high reliability monitoring.
2.Core functions and technical characteristics
1.Core functions
Framework configuration and data interaction:
Supports Bently’s proprietary protocol,communicates with the host computer or external processor through the RS-232/RS-422 interface,with a baud rate of up to 38.4K(auto-adjustment).
Provide daisy chain connection function,supports multi-frame cascade,and expands system scale.
Redundant monitoring(TMR version):
Continuously compare the output data of the three redundant monitors,if any channel deviates from the set percentage range,mark a fault and trigger a system event list alarm.
Status monitoring and control:
The front panel LED indicates the module’s operating status(OK,TX/RX,TM,CONFIG OK),and supports frame reset,address setting and configuration mode switching(RUN/PROGRAM).
2.Technical parameters
Parameters Specifications
Communication interface RS-232(maximum 30m),RS-422(maximum 1200m)
Baud rate max.38.4K(auto-adjustment)
Power consumption Typical value 4.75W
Address range 63 optional addresses(TMR version supports 127 addresses)
Relay output 24Vdc/120Vac,5A,20W/600VA
Protocol supports Bently proprietary protocol,Modbus RTU/ASCII
Certification Standards API 670,IEEE 1156,ATEX Zone 2(optional)
3.Hardware design
Installation specifications:
Must be installed in frame slot 1,close to the power supply module,ensuring power supply stability(-24VDC±0.5%).
Supports hot swapping,but avoids removing RIM or TMR modules during runtime to prevent data loss.
Scalability:
It can be combined with the Transient Data Interface Module(TDI)to achieve dynamic data acquisition and Ethernet communication(10/100 Base-T or optical fiber).
III.Application scenarios
Industrial machinery monitoring:
Used for vibration,displacement and speed monitoring of rotating machinery(such as turbines,compressors),meeting API 670 standards.
Electricity and Energy Systems:
Monitor the operating status of generators and transformers to provide fault warning and protection.
Chemical and petroleum industries:
Collect key equipment data in real time to prevent production interruptions caused by mechanical failures.
