商品說明

Gravity: Analog Signal Isolator 模擬信號隔離器 DFRobot原廠

在許多情況下,需要電隔離以確保傳感器的可靠操作。有些傳感器,例如 pH傳感器 和電導率傳感器,當它們連接到相同的電源時,它們會相互干擾並且不能在同一容器中正確測量。為了確保傳感器穩定可靠地運行而沒有干擾,有必要隔離信號和電源。

重力:模擬信號隔離器可有效防止傳感器之間的電氣干擾。該模塊具有板載5V隔離電源,可直接為傳感器供電。因此,您不需要準備外接電源,這樣簡單實用!電線連接器專為DFRobot 3Pin模擬傳感器設計,即插即用,無需焊接。模擬信號傳輸比為1:1,當該模塊連接到電路時,這對傳感器的輸出信號的影響非常小。此外,您不需要更改主板的代碼。

該anlaog信號隔離器適用於防止傳感器之間的干擾,例如需要防止水傳感器之間干擾的多參數水質監測系統。

該產品幾乎與DFRobot生產的所有模擬傳感器兼容。它可以滿足需要電隔離的情況下的各種需求。
  • MCU端子(非隔離端子)應提供5.0±0.1V的精確電壓。輸入電壓精度越高,模擬輸出信號的精度越高。
  • 該模塊在工作期間消耗相對較大的電流,因此您最好為Arduino板提供外部電源,以保證足夠的功率和電壓精度。
  • 請注意傳感器或模塊的工作電流,SEN端子的最大輸出電流為170mA。
  • MCU端子(非隔離端子)的GND和SEN端子(隔離端子)的GND彼此隔離。不要將它們短路。
  • 隔離器工作時產生熱量是正常的。

Gravity: Analog Signal Isolator

In many cases, electrical isolation is required to ensure reliable operation of the sensors. Some sensors, such as pH sensors and conductivity sensors,they will interfere with each other and do not measure properly in the same container when they connect to the same power .To ensure stable and reliable operation of the sensors with no interference,it is necessary to isolate the signal and the power.

Gravity: Analog Signal Isolator is efficient in preventing the electrical interference between sensors. This module has an onboard 5V isolation power which could directly supply to the sensor. Therefore, you do not need to prepare the external power, such an easy and practical! The connector of wires are special designed for DFRobot 3Pin analog sensor, plug and play, no need for soldering. The analog signal transmission ratio is 1:1, which contributes to a very small impact on output signals of sensors when this module connect into the circuit. Futher more, you do not need to change the code of the mainboard.

This anlaog signal isolator is applicable to prevent interferences between sensors, such as multi-parameter water quality monitoring system that need to prevent interferences between water sensors.

Gravity: Analog Signal Isolator Interface - DFRobot
Gravity: Analog Signal Isolator Interface

This product is almost compatible with all analog sensors produced by DFRobot. It could satisfy varied demands in situations which require electrical isolation.

  • The MCU terminal (non-isolation terminal) should be provided with precise voltage of 5.0±0.1V. The higher the precision of input voltage, the higher the precision of analog output signal.
  • This module consumes relatively large current during operation, so you’d better to provide external power supply to Arduino board to guarantee enough power and voltage precision.
  • Please pay attention to the operating current of your sensor or module, the maximum output current from SEN terminal is 170mA.
  • The GND of the MCU terminal(non-isolation terminal) and the GND of SEN terminal (isolation terminal) are isolated from each other. Do not short circuit them.
  • It is normal for the isolator generates heat while working.
