1900/65A 172323-01 通用设备监视器

本特内华达1900/65A通用设备监视器旨在持续监测和保护各种应用和行业中使用的设备。该监视器的低成本使其成为通用机器和过程的理想解决方案，可以从持续监控和保护中受益。

1900/65A提供4个传感器输入和4个温度输入。软件可以配置每个传感器输入，以支持2线和3线加速度计，速度传感器或接近传感器。每个温度输入支持E、J、K和T型热电偶，以及2线或3线rtd。

1900/65A提供6个继电器输出，4个4-20 mA记录仪输出和一个专用缓冲输出。用户可以使用1900配置软件配置继电器触点打开或关闭根据OK，警报和危险状态的任何通道或通道的组合，并提供数据从任何通道上的任何变量的任何记录器输出。专用缓冲输出可以为每个换能器输入提供信号。

Modbus®网关选项允许监视器直接向任何Modbus客户端提供静态变量，状态，事件列表，时间和日期信息，包括分布式控制系统(dcs)，监控和数据采集(SCADA)系统，可编程逻辑控制器(plc)或System 1®软件。监视器使用内部计数器和Modbus客户端/主时间引用来生成时间和日期信息。用户可以通过订购1900/01通信升级(参见订购信息部分)来升级没有Modbus网关的监视器。1900/65A支持通过以太网和软件可配置的RS232/485串口进行Modbus通信。

用户使用在笔记本电脑或PC机上运行的软件创建配置文件，并通过内置的以太网连接将配置文件下载到监视器上，从而定义监视器操作和Modbus Gateway寄存器映射。1900/65A将配置信息永久存储在非易失性存储器中，并可以将这些信息上传到PC以进行更改。

1900/65A支持一个可选的显示/键盘来查看通道信息或进行较小的配置更改。这允许1900/65A作为一个独立的包操作。如果需要，用户可以将显示器安装到距离监控模块75米(250英尺)的地方。

The Bently Nevada 1900/65A General Purpose Equipment Monitor is designed to continuously monitor and protect equipment that is used in a variety of applications and industries. The monitor’s low cost makes it an ideal solution for general-purpose machines and processes that can benefit from continuous monitoring and protection.

The 1900/65A provides four transducer inputs and four temperature inputs. Software can configure each transducer input to support 2- and 3-wire accelerometers, velocity sensors or proximity sensors. Each temperature input supports Type E, J, K, and T thermocouples, and 2- or 3-wire RTDs.

The 1900/65A provides six relay outputs, four 4-20 mA recorder outputs, and a dedicated buffered output. The user can use the 1900 Configuration software to configure the relay contacts to open or close according to the OK, Alert and Danger statuses of any channel or combination of channels, and to provide data from any variable from any channel on any recorder output. The dedicated buffer output can provide the signal for each transducer input.

A Modbus® Gateway option allows the monitor to provide static variables, statuses, event list, time and date information directly to any Modbus client, including Distributed Control Systems (DCSs), Supervisory Control and Data Acquisition (SCADA) systems, Programmable Logic Controllers (PLCs), or System 1® software. The monitor uses an internal counter and a Modbus client/master time reference to generate time and date information. Users can upgrade monitors without the Modbus Gateway by ordering the 1900/01 Communications Upgrade (see the Ordering Information section). The 1900/65A supports Modbus communications via Ethernet and a software-configurable RS232/485 serial port.

The user defines monitor operation and the Modbus Gateway register map by using software running on a laptop or PC to create a configuration file and download the file to the monitor through the built-in Ethernet connection. The 1900/65A permanently stores configuration information in non-volatile memory, and can upload this information to the PC for changes.

The 1900/65A supports an optional display/keypad to view channel information or make minor configuration changes. This allows the 1900/65A to operate as a stand-alone package. If desired, the user can mount the display up to 75 metres (250 feet) from the Monitor Module.
