1 Channel 5V Relay Module with Optocoupler Isolation Relay Single-chip Extended Plate High Level Trigger

Description 1 The module meets the safety standards and there are isolation grooves between the control area and the load area 2 Module with optocoupler isolation can trigger more reliably and stably 3 Adopt double sided FR 4 circuit board design and high end patch technology 4 Use genuine relay control 5 It has power supply and relay action instructions It can absorb and close brightly and disconnect lightly 6 When there is a high level signal at the input end of the signal the common end and the normal beginning will be connected 7 Relays can directly control all kinds of equipment and loads 8 There is a normally open and a normally closed contact 9 Blue KF301 terminal connection control line is more convenient 10 Module size 53x18x18 5mm Net weight 16gModule Interface VCC Connect the positive pole of the power supply supply by relay voltage GND Connect power supply negative poleIN Relay Module Signal Trigger High Level Trigger is Effective Meaning of high level and low level High level trigger refers to a trigger mode connected with the trigger terminal by the positive voltage of the VCC terminal When the trigger terminal has a positive voltage or reaches the trigger voltage the relay sucks Low level trigger refers to a trigger mode connected with the trigger terminal by the negative voltage of the GND terminal When the trigger terminal has a voltage of 0V or a voltage low enough to trigger the relay sucks Relay contact capacity 250V 10A AC or
