190065A

1900/65A 提供四个传感器输入和四个温度输入。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 提供六个继电器输出、四个 4-20 mA 记录仪输出和一个专用缓冲输出。用户可以使用 1900 配置软件根据任何通道或通道组合的正常、警报和危险状态将继电器触点配置为打开或关闭，并在任何记录仪输出上提供来自任何通道的任何变量的数据。专用缓冲器输出可为每个传感器输入提供信号。

用户通过使用笔记本电脑或 PC 上运行的软件来定义显示器操作和 Modbus 网关寄存器映射，创建配置文件并通过内置以太网连接将文件下载到显示器。1900/65A 将配置信息永久存储在非易失性存储器中，并可以将此信息上传到 PC 进行更改。

1900/65A 支持可选的显示屏/键盘来查看通道信息或进行较小的配置更改。这使得 1900/65A 能够作为独立套件运行。如果需要，用户可以将显示器安装在距离显示器模块 75 米（250 英尺）的地方。

The Bently 1900/65A universal device monitor is designed to continuously monitor and protect devices used in a variety of applications and industries. The low cost of this monitor makes it an ideal solution for general-purpose machines and processes that can benefit from continuous monitoring and protection.

The 1900/65A offers four sensor inputs and four temperature inputs. The software can configure each sensor input to support 2-wire and 3-wire accelerometers, speed sensors, or proximity sensors. Each temperature input supports E, J, K, and T thermocouples and 2 – or 3-wire RTDS.

The 1900/65A offers six relay outputs, four 4-20 mA recorder outputs, and a dedicated buffer output. Users can use the 1900 configuration software to configure relay contacts to open or close based on the normal, alarm, and hazardous states of any channel or combination of channels, and to provide data on any variable from any channel on any logger output. A dedicated buffer output provides a signal for each sensor input.

Users define display operations and Modbus gateway register maps by using software running on a laptop or PC, create a configuration file and download the file to the display via a built-in Ethernet connection. The 1900/65A stores configuration information permanently in non-volatile memory and can upload this information to a PC to make changes.

The 1900/65A supports an optional display/keyboard to view channel information or make minor configuration changes. This allows the 1900/65A to operate as a standalone package. If desired, the user can install the display 75 meters (250 feet) away from the display module.
