描述

1 路 5V 繼電器模組 光耦隔離 可設定高低電平觸

  1. 模塊採用正品優質繼電器,常開接口最大負載:交流250V/10A,直流30V/10A;
  2. 採用貼片光耦隔離,驅動能力強,性能穩定;觸發電流5mA;
  3. 模塊工作電壓 5V
  4. 模塊可以通過跳線設置高電平或低電平觸發;
  5. 容錯設計,即使控制線斷,繼電器也不會動作;
  6. 電源指示燈(綠色),繼電器狀態指示燈(紅色)
  7. 接口設計人性化,所有接口均可通過接線端子直接連線引出,非常方便
  8. 設有4個固定螺栓孔,孔3.1mm

二 模塊接口:

  • DC+:接電源正極(電壓按繼電器要求)
  • DC-:接電源負極
  • IN:可以高或低電平控制繼電器吸合

繼電器輸出端:

  • NO:繼電器常開接口,繼電器吸合前懸空,吸合後與COM短接
  • COM:繼電器公用接口
  • NC:繼電器常閉接口,繼電器吸合前與COM短接,吸合後懸空

高低電平觸發選擇端:

  • 跳線與LOW短接時為低電平觸發;
  • 跳線與high短接時為高電平觸發。

 1 Channel Optocoupler High/Low Level Relay Module 5V DC

  • The module uses genuine quality relay, normally open interfaces Maximum load: AC 250V/10A, DC 30V/10A;
  • Using SMD optocoupler isolation, driving ability, stable performance; trigger current 5mA;
  • The module Operating voltage 12V;
  • The module can be high or low by a jumper setting trigger;
  • fault-tolerant design, even if the control line is broken, the relay will not operate;

Module description:
1. the module uses genuine quality relay, normally open interfaces Maximum load: AC 250V/10A, DC 30V/10A;
2. using SMD optocoupler isolation, driving ability, stable performance; trigger current 5mA;
3. the module Operating voltage 12V;
4. the module can be high or low by a jumper setting trigger;
5. fault-tolerant design, even if the control line is broken, the relay will not operate;
6. the power indicator (green), the relay status indicator (red)
7. the interface design of human nature, all interfaces are available through a direct connection terminal leads, very convenient
8. module size: 50mm*26mm*18.5mm (L*W*H)

Module interface:
1. DC+: positive power supply (VCC)
2. DC-: negative power supply (GND)
3. IN: can be high or low level control relay

Relay outputs:
1. NO: normally open relay interface
2. COM: Common Interface Relays
3. NC: normally closed relay interface

High and low level trigger options:
It is low level trigger when jumper connect to LOW pin
It is high level trigger when jumper connect to HIGH pin
