描述
主要产品详情及功能
超速保护：该模块的主要功能是持续监测关键机械（如涡轮机、压缩机和泵）的转速并检测超速情况。这对于防止灾难性故障和确保人员安全至关重要。
符合API 670和612标准：其设计符合美国石油学会(API)标准670和612的严格超速保护要求，这些标准在石油、天然气和石化行业得到广泛认可。
I/O模块：133396-01是一个I/O模块，这意味着它可以处理来自速度传感器的输入信号并进行处理。它还可以向控制和保护系统中的其他组件提供输出信号。
传感器兼容性：每个模块只接受一个传感器信号，通常来自：
接近探头：用于非接触式速度测量，提供精确读数。
磁性拾音器：另一种常见的速度传感器。
输入信号电压范围为+10.0 V至-24.0 V。
高精度、快速响应：
精度：通常为满量程的±0.1%，确保高精度转速测量。
响应时间：非常快，通常小于5毫秒（在某些情况下甚至小于1毫秒），能够快速响应超速事件并及时触发警报或跳闸。
报警设定点：用户可以配置多个转速报警设定点：
警报级别：用于警告操作员即将发生的危险。
危险（超速）设定点：用于启动跳闸或停机以保护机器。
所有报警设定点均可通过软件配置，通常可在满量程转速范围的0至100%之间调节。
冗余系统功能：为了实现最高可靠性，3500/54（通常与3500/53搭配使用）可配置为2选2或2选3表决系统。这种冗余设计可确保单个模块故障不会导致误跳闸或漏跳闸，从而实现高度容错。
输出：
记录仪输出：提供与模块满量程转速范围成比例的+4至+20 mA直流输出，可与DCS、SCADA或其他数据采集系统集成。这些输出短路不会影响模块功能。
报警LED：前面板LED指示报警状态和系统状态（正常、TX/XR、旁路、测试模式）。
环境密封：模块采用环氧树脂密封，可在恶劣的工业环境下提供卓越的防护。
3500系列集成：它是机架式Bently Nevada 3500系列监控系统的组成部分，与机架中的其他模块共享电源、通信和处理功能。

Key Product Details and Functions
Overspeed Protection:The primary function of this module is to continuously monitor the rotational speed of critical machinery(like turbines,compressors,and pumps)and detect overspeed conditions.This is vital for preventing catastrophic failures and ensuring personnel safety.
API 670&612 Compliance:It’s engineered to meet the stringent overspeed protection requirements of American Petroleum Institute(API)Standards 670 and 612,which are widely recognized in the oil,gas,and petrochemical industries.
I/O Module:The 133396-01 is an I/O module,meaning it handles the input signals from speed sensors and processes them.It also provides output signals to other components in the control and protection system.
Transducer Compatibility:It accepts a single transducer signal per module,typically from:
Proximity Probes:For non-contact speed measurement,providing precise readings.
Magnetic Pickups:Another common type of speed sensor.
The input signal has a voltage range of+10.0 V to-24.0 V.
High Accuracy and Fast Response:
Accuracy:Typically±0.1%of the full scale,ensuring highly accurate rotational speed measurement.
Response Time:Very fast,often less than 5 milliseconds(or even<1 millisecond in some contexts),enabling rapid reaction to overspeed events and timely activation of alarms or trips.
Alarm Setpoints:Users can configure multiple speed alarm setpoints:
Alert levels:For warning operators of approaching danger.
Danger(Overspeed)setpoint:For initiating trips or shutdowns to protect the machine.
All alarm setpoints are software-configurable and typically adjustable from 0 to 100%of the full-scale speed range.
Redundant System Capability:For maximum reliability,the 3500/54(often paired with the 3500/53)can be configured in a 2-out-of-2 or 2-out-of-3 voting system.This redundancy ensures that a single module failure won’t lead to a false trip or a missed trip,making it highly fault-tolerant.
Outputs:
Recorder Outputs:Provides a+4 to+20 mA DC output proportional to the module’s full-scale speed range,allowing integration with DCS,SCADA,or other data acquisition systems.Short circuits on these outputs do not affect module functionality.
Alarm LEDs:Front panel LEDs indicate alarm conditions and system status(OK,TX/XR,Bypass,Test Mode).
Environmental Sealing:The module is epoxy sealed,providing excellent protection against harsh industrial environments.
3500 Series Integration:It is an integral part of the rack-based Bently Nevada 3500 Series Monitoring System,sharing power,communication,and processing with other modules in the rack.
