描述
8 路 5V 繼電器模組 光耦隔離 可設定高低電平觸
- 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;
- 採用貼片光耦隔離，驅動能力強，性能穩定；觸發電流5mA；
- 模塊工作電壓 5V
- 模塊可以通過跳線設置高電平或低電平觸發；
- 容錯設計，即使控制線斷，繼電器也不會動作；
- 電源指示燈（綠色），繼電器狀態指示燈（紅色）
- 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
- 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。
接線參考
8 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 5V;
- 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:
