#10Gtek# 12V one Channel Relay Module, high and Low Level Trigger Module
Product Features
- The module can be used as a microcontroller development board module, can be used as home appliance control lights flashing.
- When there is a signal at the signal input end, the common end and the normally open end will be turned on, control DC or AC signal, you can control 220V AC load.
- Low-level triggering refers to the triggering mode of the voltage between the signal input terminal and ground is OV, which can be understood as a way to trigger the short circuit of the signal input terminal and the GND negative terminal.
- Module interface design humane can be connected directly via terminal wiring leads, very convenient.
