- Control indicator lamp
- With 4 fixed screw holes, a hole diameter of 3.1mm, convenient installation, and fixation
Pin Descriptions:
- DC +: DC power supply positive;
- DC -: DC power supply module negative;
- IN: Signal input terminal(support High/Low Level switch freely);
- Normally open (NO): Relay normally open;
- Common terminal (COM): Relay common;
- Normally closed terminal (NC): relay normally closed terminal
Note:
On the high-level and low-level-triggered mode, friends who do not understand, have a look:
- High-level trigger refers to the signal voltage between input and trigger and can be understood as a signal input with VCC cathode short-circuit triggered away.
- Low-level trigger refers to the signal voltage between the input terminal and Earth OV trigger, which can be understood as a signal input terminal and the GND negative electrode short circuit triggered is a way 1-channel relay module connection.
