5v Dc 4 Channel Relay Module For Arduino In Pakistan

2 Channel Relay Module Relay Board Arduino Relay Module With Optocoupler allows a wide range of microcontrollers such as Arduino, AVR, PIC, ARM with digital outputs to control larger loads and devices like AC or DC Motors, electromagnets, solenoids, and incandescent light bulbs. 4–channel relay interface board and each channel need a 15-20mA driver current. It can be used to control various appliance

1 Channel 5V Arduino Relay Module for Arduino PIC AVR DSP ARM. Single-channel relay, a wide range of microcontrollers such as Arduino, AVR, PIC, ARM, and so on can control it. The 5V relay module circuit, each needs a 15mA-20mA driver current and is equipped with a high current relay: DC 30V / 10A, AC 250V / 10A. This one channel module has a standard interface that can be compatible with a microcontroller. This 5V Arduino relay module has 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 away. Low-level trigger refers to the signal voltage between the input terminal and Earth OV trigger, which can be understood as the signal input terminal and the GND negative electrode short circuit triggered away 1-channel relay module connection.

The Single Channel Relay Module is a convenient board that can be used to control high voltage, high current loads such as motor, solenoid valves, lamps, and AC load. this single-channel 5V 30A Relay Module board with LED indicators can be controlled by microcontrollers such as Arduino, AVR, PIC, ARM any other microcontroller operating at 5V. The user can choose the relay control level, which can be a high level off, also can be low level and off. The Single-channel 5V 30A Relay Module contains a limited flow resistance, can directly use the power supply is a negative control, you can also use the MCU I/O control.
