英國Hansford HS-530型是一款4通道輸出的振動模塊，與100mV/g恒定電流型加速度傳感器配套使用，用于振動監測與分析。HS-530外形緊湊，導軌式安裝在塑料外殼里，工作電壓：24VDC, 25mA.

The HS-530 Quad Output Vibration Module is designed to operate with 100mV/g constant current type accelerometers to provide four outputs useful in vibration monitoring and analysis. The unit is housed in a compact DIN-Rail mounting plastic case and operates from 24VDC at 25mA. Terminal connections are shown in Fig.1.overleaf.

供電加速度傳感器

HS-530能夠給加速度傳感器提供3.6mA的恒定電流，這樣傳感器只需要直接連接振動模塊的輸入端口。

Accelerometer Power. The HS-530 provides a 3.6mA constant current supply to an accelerometer which connects directly to the module input terminals.

LED狀態指示

當傳感器與模塊連接成功后，模塊前面板上會亮起綠色LED燈；當連接錯誤或者電線短路時，LED不會亮起。這樣可以有效避免因輸入信號造成的問題，0-10V輸出會被設定為0V。

TDX OK LED. A green LED on the front of the unit indicates correct connection of the accelerometer. The LED will not light if input wiring short or open-circuits are present. To prevent problems due to spurious input signals, both 0-10V outputs are set to 0V if the TDX OK LED is not lit.

AC輸出

模塊通過前面板的BNC連接器，輸出一個與加速度型號成比例的帶緩沖未過濾AC信號。當數據采集器監測輸入信號，進行振動分析，那么該信號必須是AC輸入信號，并給傳感器供電。

AC Output. A buffered, but un-filtered AC output proportional to the acceleration signal is provided via a BNC connector mounted on the front panel. The 100mV/g signal is not AC coupled and swings about the accelerometer bias voltage level. If a data-collector is used to monitor this signal for vibration analysis, it must set for AC input and have its sensor power function turned off.

速度輸出

HS-535也可以輸出一個0-10V信號，與RMS速度（mm/s）對應。模塊信號調理儀擁有高低通濾波功能，對測量帶寬進行限制，限制范圍：10Hz - 1kHz，符合旋轉電機振動幅度ISO 10816標準。0-10V標準輸出范圍：0-20 mm/s，加速度版本的輸出為 g rms。

Velocity Output. This is a 0-10V output proportional to rms velocity in mm/s. The signal conditioner has high and low pass filters to limit the measurement bandwidth to 10Hz to 1kHz as defined in ISO 10816 which lists recommended vibration limits for rotating machines. The output range is set at the factory at 0-10V = 0-20mm/s as standard. For acceleration versions, this output is 0- 10V proportional to g rms.

加速度g輸出

0-10V輸出可檢測球或滾子軸承的問題，該型號可轉換成對應的軸轉速。輸入電路帶寬為500Hz-10kHz，出廠標準輸出范圍為0-10V-0-10gE。

Enveloped g Output. This 0-10V output is useful for detecting problems in ball or roller bearings where signals from high frequency impacts are masked by the lower frequency vibrations proportional to shaft rotational speed. The enveloper input circuit bandwidth is 500Hz to 10KHz and the output range is set at the factory 0-10V =0-10gE as standard.

AC包絡線輸出

AC包絡線輸出是包絡檢波電路產生的緩沖AC輸出，9VDC的震蕩基準。100mV/g的輸出信號可直接傳輸至數據采集產品，進行振動分析。

6. AC Envelope Output. This is a buffered AC output from the enveloper circuit which swings about a 9VDC reference level. The 100mV/g signal can be used for vibration analysis via a Data-Collector.
