ACEIRMC 10pcs 12v Relay Board for Raspberry Arduino Relay Module 1 Channel Opto-Isolated High or Low Level Trigger (12V)

Product Details

This Relay Board provides a single relay that can be controlled by any12V digital output from your microcontroller.
Fault tolerant design, even if the control line is broken, the relay will not operate; And interface design humanized, all the interface can be directly connected through the terminal lead, so convenient.
These 12v relay board works well for Arduino/ ARM /PIC /AVR /MCU/Raspberry/CNC machine/ PS4 etc.
The isolation circuit prevent damages to I / O port by relay switch current.The module has a jumper so you can set rather the unit state changes with high or low signal. Has screw terminals for relay (NC,C,NO) and for input; Coil +, coil - and trigger.
