12V 1 Channel Relay Module with Optocoupler

This 1 Channel 12V Relay Module with Optocoupler satisfy the safety guideline as control regions and load region have the isolation groove. Optical coupling isolation module.

The setting off of 1 Road/Channel Relay Module is dependable, more steady. The dual FR 4 circuit board configuration, very good quality SMT process. It has power and relay activity directions. Relays terminals (C, NC, NO) are open through screw terminals which makes wiring up the board exceptionally simple. The relay is securely determined by semiconductor BC547 consequently your input device, like Arduino, is safeguarded from the relay circuit.

The inputs of 1 Channel 12V Relay Module are isolated to safeguard any sensitive control circuitry.

A wide scope of microcontrollers like Arduino, AVR,PIC, ARM, etc can control it.

The utilization of such high-voltage relay kills the chance of warming up of the relay as electromechanical relay limits the current consumption as per a voltage rating.

Module interface:

The positive (according to the relay voltage VCC: connect power supply)
GND: connect power negative
IN: relay module (effective) high-level trigger signal trigger end

High level and Low-level Definations

1. High-level trigger refers to using the anode voltage at the VCC connection way of a trigger and triggers the end when the trigger side has a positive voltage or to trigger voltage when the relay is off.
2. Low-level trigger refers to using the negative voltage at the GND connection way of a trigger and triggers the end when the trigger side has 0 v low voltage or voltage to can trigger, the relay is off.
