1 2 4 8 Channel 5V 12V Relay Module with Optocoupler, High Low Level Trigger Shield for Arduino PIC AVR MCU DIY Projects

8 Channel Relay Module with Optocoupler

Features:
1.Dual trigger design, use a dedicated two-way driver IC.
2.Strong resist interference, use diode continued current to protect it.
3.The relay contact part adopts double cloth line for large current, safe and reliable.
4.The input and output are 5.08mm wiring terminals, wiring is more convenient, suitable for PLC control.
5.Input terminals can be arbitrarily set high and low level, the control mode is more flexible.
6.Equipped with fixing screw hole, easy to install.
7.Each way module can be set high or low triggered by jumper.
