【12V 1 Channel Relay Module】- This Relay Board provides a single relay that can be controlled by any12V digital output from your microcontroller.
【Main Specification】- Peak Load of NO Connector: AC125~250V/10A, DC28~30V/10A; Trigger Current: 5mA;The Module Operating Voltage:12V; 4pcs * 3.1 mm Fixed Bolt Hole.
【Adopted SMD Optocoupler Isolation& jumper Set】- 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.
【Wide Application】-These 12v relay board works well with ARM /PIC /AVR /MCU/Raspberry/CNC machine/ PS4 etc.
【Humanization Design On Interfaces】- All interfaces can be directly wired out through the terminals.Fault-tolerant design;fault-tolerant design,even if the control line is broken, the relay will not operate.
