1. Analog signal input(Universal input)
記錄儀設計最大6通道萬能信號輸入，支持mV、V、mA、熱電阻、熱電偶信號。通道信號類型通過輸入組態(tài)設置，記錄儀根據組態(tài)設置的信號類型，自動切換對應的采集電路，信號采集周期為1秒。
The channel can independently configure and set the unit, range, decimal point, adjustment, filtering, disconnection processing, small signal removal and other parameters.

2. Data recording and alarm, power-down and logs
記錄儀根據系統(tǒng)組態(tài)設定記錄間隔實時記錄通道采樣數據，記錄間隔可選：1秒、2秒、5秒、10秒、15秒、30秒、1分、2分、5分、10分、30分、1小時。記錄儀內部存儲器16MB，可儲存90萬條記錄，6通道1秒記錄間隔存儲10天，增大記錄間隔，記錄周期相應增加。記錄儀同時記錄運行時產生的通道報警、儀表掉電、操作日志信息，各256條記錄，記錄模式為循環(huán)覆蓋存儲。

3. Display of data, curves and records
記錄儀采用4寸高清彩色液晶屏，分辨率為800*480像素。記錄儀設計有數顯、棒圖、實時曲線、儀表盤多種數據顯示查看方式，可查看歷史曲線、報警列表、掉電記錄、操作日志等歷史數據。記錄儀配備中英雙語系統(tǒng)，可自主切換使用。

4. Alarm relay output
記錄儀設計最多6路報警繼電器輸出，繼電器類型為常開型。通過報警組態(tài)設置，可任意指定繼電器觸點與通道關聯，可設置高報、低報、高高報、低低報四種報警類型，可設置報警回差、繼電器延時參數。

5. 24VDC Output
The recorder is equipped with 2-loop 24VDC power outputs, which are used to power the sensor, and can directly drive the two-wire sensor. The current loop is connected in series with the input channel of the recorder.

6. RS485 with Modbus RTU
The recorder is equipped with one RS485 communication interface, adopts standard Modbus RTU communication protocol, supports real-time data of channels, alarm status of channels and other data.

7.4-20mA變送輸出
記錄儀可選配最多2路4-20mA變送輸出功能，可通過輸出組態(tài)設置，配置輸出通道與輸入通道的變送關系。

8.微型打印機接口
Optional micro printer port, automatic real-time printing of data and curves, and manual printing of historical data and curves.

9.USB數據備份
The recorder is equipped with USB2.0 interface, which manually exports historical data to USB stick through USB interface and automatically regularly backup historical data.

10.組態(tài)導入及固件更新
Support for importing and exporting configuration parameters and update instrument firmware through USB interface.

11.流量累積（無溫壓補償）
The recorder supports the channel flow accumulation, and does not have the temperature and pressure compensation function.

12.真空度算法
The recorder supports the channel vacuum algorithm, and combines the output signal with the vacuum meter to calculate, store and display the data in the form of vacuum.

13.上位機數據管理軟件
The recorder provides the data management software, supports the data export of superior disk, and supports the real-time monitoring data of single machine. Support the curve and the data display mode, you can export the EXCEL report.
