The 1 channel 5V relay designed specifically for Arduino, PIC, AVR, DSP. In this relay module, Each one needs 15mA – 20mA driver current and Equipped with a high current relay: DC 5V / 10A, AC 250V / 10A As this relay is not optoisolated, So, the relay and signal both operate from a single power source. This module can handle up to 2A of current. This relay works as Single Pole Double Throw (SPDT) switch with common (C), normally open (NC), normally closed (NC) pin connected to the screw terminal for easy accessibility. This high-level trigger ac power relay board can be controlled directly by microcontrollers. This module can switch up to 10A at 250 V AC.
A relay defined as an electromagnetic switch operated by a relatively small current that can control a much larger current. The relay normally open interface maximum load: AC 250V/10A, DC 30V/10A. It offers a trigger current of 5mA, and a module working voltage of DC 5V. A jumper to set a high level or a low level can trigger each channel of the module. Moreover, all the module sizes connected directly via the terminal block, which is quite convenient and practical.
This 1 Channel Relay Module has connections for all 3 terminals of the relay i.e. NO, NC, and COM. There exist 2 LED on the relay module in which red indicates the status of the relay and green for power. When the input digital signal is high, the relay is switched ON (closed), else switch is OFF (opened). This module can control various applications and equipment with a large current that is compliant with international safety.
