【Control Devices】The 1-channel relay module uses genuine high quality DC5V relay and SMD opto-isolator supporting high/low level trigger, widely apply to control various AC/DC appliances, and other devices with large current.
【Load Range】NO(Normally open) maximum load < AC 250V/10A, < DC 30V/10A. Trigger current of opto-isolator: 5mA.
【Fault-tolerant Design】The relay will not operate even if the control line is disconnected.
【Universal Interface】Equipped with screwed terminal plate and fixed bolt holes(diameter: 3.1 mm) on both sides for easy installation.
【High Compatibility】The relay module can be controlled directly by 5V logic signals from microcontroller(8051, AVR, PIC, DSP, ARM, Raspberry Pi, MSP430, TTL logic etc)

How high/low level triggers selection terminal

High level trigger acts when jumper wire and high pin are short connected

Low level trigger acts when jumper wire and low pin are short connected

Input interface:

DC+ : positive pole of power supply (VCC, voltage=5V)

DC- : negative pole of power supply(GND)

IN : connection to control relay pickup by high/low level trigger

Output interface:

NO : connection of normally open state(the relay switch is dangling before pickup, the switch will connect with "COM" after pickup)

COM : common interface of relay switch

NC : connection of normally closed state(the relay switch is connected with "COM" before pickup, the switch will be dangling after pickup)

Package List:

10x 5V 1-Channel Relay Module


Connection Method of Normally Open Circuit - When the signal trigger terminal has a high or low level signal (as per setting function), the relay picks up, which is equivalent to the switch closing. At this time, the circuit is turned on, the device will be energized and work normally.	Connection Method of Normally Closed Circuit - When the signal trigger terminal has a high or low level signal (as per setting function), the relay picks up, which is equivalent to the switch being turned off(initial switch state is opened). At this time, the device will be powered off and stop working.	Diagrammatic drawing and schematic circuit diagram of relay connection - When there is no voltage in the relay coil, the relay does not pick up, the common contact is connected to the NC contact. - When there is voltage, the relay picks up, and the common contact is connected to the NO contact.
