1-channel 2-channel 4-channel 8-channel 5V relay low level trigger

Multiple specifications to choose from

Product Introduction

1. This module complies with safety standards and has isolation slots between the control area and the load area;

2. Using relays;

3. Equipped with power and relay action indicators, it lights up when in and out, but does not light up when disconnected;

4. When there is a signal at the signal input terminal, the common terminal and the normal terminal will conduct;

5. Can be used as a microcontroller development board module and can be used for home appliance control;

6. Control DC or AC signals, capable of controlling 220V AC loads;

7. There is a normally open and a normally closed contact;

8. The blue KF301 terminal is more convenient for connecting control wires.

For the explanation of high-level and low-level triggering methods, please take a look if you don't understand:

High level triggering refers to a triggering method where there is a voltage between the signal input terminal and ground, which can be understood as a way of triggering when the signal input terminal is short circuited to the positive pole of VCC;

Low level triggering refers to the triggering method where the voltage between the signal input terminal and ground is OV, which can be understood as a way of triggering when the signal input terminal is short circuited to the negative terminal of GND
