描述
本特利3500/20是一款机架接口模块（RIM），是3500机架的主要接口。以下是其产品详情：
功能：支持专有协议，用于配置机架和检索机械数据，可与兼容的本特利内华达外部通信处理器（如TDXnet、TDIX和DDIX等）配合使用。
安装位置：必须位于机架的插槽1中，靠近电源。
功耗：典型功耗为4.75瓦。
通信参数：前面板数据通信采用RS232串行通讯，数据速率38.4k波特；输入/输出模块通信支持RS232/RS422串行通讯，内部调制解调器通讯数据率为38.4k波特，串行通讯为14.4k波特。
指示灯：前面板有正常LED、发射/接纳LED、TM LED、装备正常LED等，用于指示模块的工作状态、通讯状态等。
继电器：配备正常继电器，用于指示3500机架的运转状况，24伏直流电/120伏交流电时额定电流为5A，正常继电器为“正常通电”运转，用户可选择“翻开”或“已封闭”的联系人告诉不正常状况。
其他功能：机架复位按钮可清除锁定的警报和定时正常机架中的路径失败；地址转换用于设置63个可能的机架地址；配置钥匙锁用于将3500机架放入“运转”形式或“程序”形式。
此外，对于三模冗余（TMR）应用，3500系统需要TMR版本的RIM，除了标准RIM功能，TMR RIM还执行“监控”渠道对比功能。3500/20模块的尺寸为高9.5英寸，宽0.96英寸，深9.52英寸，重量约0.91公斤。
The Bentley 3500/20 is a rack interface module(RIM),the primary interface for the 3500 rack.The following are product details:
Function:Supports proprietary protocols for rack configuration and mechanical data retrieval,and can be used with compatible Bently Nevada external communication processors(such as TDXnet,TDIX,and DDIX).
Mounting Location:Must be located in slot 1 of the rack,near the power supply.
Power Consumption:Typical power consumption is 4.75 watts.
Communication Parameters:Front panel data communication uses RS232 serial communication at a data rate of 38.4 kbaud;input/output module communication supports RS232/RS422 serial communication,with an internal modem communication data rate of 38.4 kbaud and serial communication at 14.4 kbaud.
Indicators:The front panel features a normal LED,a transmit/receive LED,a TM LED,and an equipment normal LED to indicate module operating status and communication status.Relays:A normal relay is provided to indicate the operating status of the 3500 rack,rated at 5A at 24VDC/120VAC.The normal relay operates in”normally energized”mode,while the user can select”open”or”closed”contact notification for abnormal conditions.
Other features include a rack reset button to clear latched alarms and timed path failures in a normal rack;address translation allows for setting 63 possible rack addresses;and a configuration key lock allows the 3500 rack to be placed in”operational”or”program”mode.
In addition,for triple modular redundancy(TMR)applications,the 3500 system requires the TMR version of the RIM.In addition to the standard RIM functionality,the TMR RIM also performs”monitoring”channel comparison functions.The 3500/20 module measures 9.5 inches high,0.96 inches wide,and 9.52 inches deep,and weighs approximately 0.91 kg.
