Relay Switch Modules

This 1-channel 5V control Single-Pole Double-Throw (SPDT) High-level trigger AC power relay board can be controlled directly via a microcontroller and switch up to 10A at 250 VAC. The inputs of 1 Channel 5V Relay Module are isolated to protect any delicate control circuitry.

The default state of the relay when the power is off for COM (Power) to be connected to NC (Normally Closed). This is the equivalent of setting the relay board IN pin to HIGH (has 5V sent to it).

A wide range of microcontrollers such as Arduino, AVR, PIC, ARM, etc can be used to control this 5V relay module

NOTE : There Is Printing Mistake On  Module 250VAC To 30VAC And 125VAC to 28VAC But Working Will Be Same.

This 1 channel 5V 10A relay control board module with optocoupler modules is compliant with international safety standards, control and load areas isolation trenches it has a single relay a genuine.

The inputs of 5V 1-Channel Relay 10A Relay Module are isolated to protect any delicate control circuitry.

The power supply and relay instructions, lit, a disconnect are off. The input signal, signal, common Terminal and start conducting. It can be used as a single chip module for appliance control and work with both DC or AC signals where you can control the 220V AC load.

A wide range of microcontrollers such as Arduino, AVR, PIC, ARM and so on can control 1 channel 5V 10A Relay Control Board Module with Optocoupler.

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, can be understood as a signal input with VCC cathode short-circuit triggered a way;
• Low-level trigger refers to the signal voltage between the input terminal and Earth OV trigger, can be understood as a signal input terminal and the GND negative electrode short circuit triggered is a way  1-channel relay module connection.

This is a 2 Channel isolated 5V 10A relay module Optocoupler for Arduino PIC ARM. It can be used to control various appliances and other types of equipment with a large current. It can be controlled directly with 3.3V or 5V logic signals from a microcontroller (Arduino, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic).

This relay has a 1×4 (2.54mm pitch) pin header for connecting power (5V and 0V), and for controlling the 2 relays.

The pins are marked on the PCB as:

• GND – Connect 0V to this pin.
• IN1 – Controls relay 1, active Low Relay will turn on when this input goes below about 2.0V
• IN2 – Controls relay 2, active Low Relay will turn on when this input goes below about 2.0V
• VCC – Connect 5V to this pin. Is used to power the optocouplers

Note: This 5V Dual Channel Relay Module is for low level trigger only. 

About high level and low level-triggered mode:

1. High-level trigger refers to the signal voltage between input and trigger, can be understood as a signal input with VCC cathode short-circuit triggered a way;
2. Low-level trigger refers to the signal voltage between the input terminal and Earth OV trigger, can be understood as the signal input terminal and the GND negative electrode short circuit triggered away  1-channel relay module connection

Jumper Instruction = The relay can be turned on when we connect 5v to one end and the other to -5v / Gnd, while talking about the jumper, if we short the VCC and the middle pin, then our relay will act as high level-triggered relay means that when we will apply 5V input on its input pin it will be turned on and when the jumper will be set to “middle and GND”, it will act as a low-level triggered relay, It means that relay will be triggered when we implement the 5V / GND on its input pin.

This is a 2 Channel 5V Relay module, be able to control various appliances, and other equipment with large current. It can be controlled directly by Microcontroller (8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic).5V 2-Channel Relay interface board and each one needs 15-20mA Driver Current Equipped with high-current relay, AC250V 10A; DC30V 10A Standard interface that can be controlled directly by microcontroller (8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic) Indication LED’s for Relay output status.
