本特內(nèi)華達(dá)1900/65A通用設(shè)備監(jiān)視器旨在持續(xù)監(jiān)測和保護(hù)各種應(yīng)用和行業(yè)中使用的設(shè)備。該監(jiān)視器的低成本使其成為通用機(jī)器和過程的理想解決方案，可以從持續(xù)監(jiān)控和保護(hù)中受益。

1900/65A提供4個(gè)傳感器輸入和4個(gè)溫度輸入。軟件可以配置每個(gè)傳感器輸入，以支持2線和3線加速度計(jì)，速度傳感器或接近傳感器。每個(gè)溫度輸入支持E、J、K和T型熱電偶，以及2線或3線rtd。

1900/65A提供6個(gè)繼電器輸出，4個(gè)4-20 mA記錄儀輸出和一個(gè)專用緩沖輸出。用戶可以使用1900配置軟件配置繼電器觸點(diǎn)打開或關(guān)閉根據(jù)OK，警報(bào)和危險(xiǎn)狀態(tài)的任何通道或通道的組合，并提供數(shù)據(jù)從任何通道上的任何變量的任何記錄器輸出。專用緩沖輸出可以為每個(gè)換能器輸入提供信號(hào)。

Modbus®網(wǎng)關(guān)選項(xiàng)允許監(jiān)視器直接向任何Modbus客戶端提供靜態(tài)變量，狀態(tài)，事件列表，時(shí)間和日期信息，包括分布式控制系統(tǒng)(dcs)，監(jiān)控和數(shù)據(jù)采集(SCADA)系統(tǒng)，可編程邏輯控制器(plc)或System 1®軟件。監(jiān)視器使用內(nèi)部計(jì)數(shù)器和Modbus客戶端/主時(shí)間引用來生成時(shí)間和日期信息。用戶可以通過訂購1900/01通信升級(jí)(參見訂購信息部分)來升級(jí)沒有Modbus網(wǎng)關(guān)的監(jiān)視器。1900/65A支持通過以太網(wǎng)和軟件可配置的RS232/485串口進(jìn)行Modbus通信。

用戶使用在筆記本電腦或PC機(jī)上運(yùn)行的軟件創(chuàng)建配置文件，并通過內(nèi)置的以太網(wǎng)連接將配置文件下載到監(jiān)視器上，從而定義監(jiān)視器操作和Modbus Gateway寄存器映射。1900/65A將配置信息存儲(chǔ)在非易失性存儲(chǔ)器中，并可以將這些信息上傳到PC以進(jìn)行更改。

1900/65A支持一個(gè)可選的顯示/鍵盤來查看通道信息或進(jìn)行較小的配置更改。這允許1900/65A作為一個(gè)獨(dú)立的包操作。如果需要，用戶可以將顯示器安裝到距離監(jiān)控模塊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.
