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:
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.
