Manufacturer Supplies New 1-Way Relay Module 5V/12V Low Level Trigger Relay Expansion Board

1 relay module 12V low-level trigger relay expansion board 12V

Product Introduction

1. This module meets the standards and has isolation slots between the control area and the load area;

2. Adopting double-sided FR-4 circuit board design and surface mount technology production;

3. Adopting Songle relay control;

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

5. When there is a low-level signal at the signal input terminal, the common terminal and the normal terminal will conduct;

6. Relays can directly control various devices and loads;

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

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

9. Module size: 43x17x18.5mm; Net weight: 15g

Module interface:

Input section:

VCC: Connect to 5V power supply (supply power according to relay voltage)

GND: Connect to a 5V power supply negative

IN: Relay module signal trigger terminal (low level trigger effective)

Meaning of high and low levels:

High level triggering refers to a triggering method that connects the positive voltage of the VCC terminal to the triggering terminal. When there is a positive voltage or triggering voltage at the triggering terminal, the relay will be closed.

Low level triggering refers to a triggering method in which the negative voltage at the GND terminal is connected to the triggering terminal. When there is a 0V voltage at the triggering terminal or the voltage is low enough to trigger, the relay will close.
