5V Relay Module - 1 Channel - Low Level Trigger

• The module complies with international safety standards, control area load area isolation groove
• Genuine relay
• With the power and relay action instructions, pull bright disconnect does not shine
• When a signal in the signal input terminal, the common terminal and the normally start conduction
• Microcontroller development board can be used as a module that can be used as a home appliance control
• The control of the DC or AC signal, can control 220V AC load
• There is a normally open and a normally closed contact
• Blue KF301 terminals to the line of control is more convenient

High level trigger is a trigger voltage between the signal input and ground can be understood as a way of the signal input terminal and VCCcathode short trigger.

Low trigger means is the voltage between the signal input terminal and the ground for the OV trigger mode can be understood as a way of thesignal input terminal and GND negative short trigger 1 relay module wiring.
