Product Description

Specification:

Channel: 1 channelControl signal: TTLWork voltage: DC 3V/3.3VMain chip: EL817, SRD-DC03V-SL-CCompatible Load:10A 250VAC, 10A 30VDCResponse time :Less than 20 millisecondsWorking Current: 65mA；Load Current: 10A maxTrigger Current: 3mASingle Socket Length: 7.5mmResponse Time: <20ms

The relay module has the output signal indicator light indicationThe signal input port can connect SCM IO port, high level signal driveDual power supply design with anti-interference ability and high reliability of photoelectric isolation protectionWith diode continuous flow protectionResponse time is less than 20 millisecondsLong life of relay can be absorbed 100,000 times continuouslyThe external connection uses the Rotary crimping terminal, causes the wiring to be more solid

Power interface:VCC: positive pole of power supply (3v/3.3v)GND: connect to the negative pole of the power supplyIN: high level control relay suction

Load interface:NO: normally open interface of the relay. The relay is suspended before suction and shorted with COM after suctionCOM: common interface of relayNC: normally closed interface of relay, short connection between relay and COM before suction and suspension after suction

Note:If you’re switching high voltages, be very careful handling this device.The terminal block screws, in particular, are at full controlled voltages. Turn off all power off before making changes.

3V 1 channel relay interface board support photocoupler isolation control,has the output signal indicator,the signal input port can connect SCM IO port, high level signal drive
Relay board provides a single relay that can be controlled by any 3V/3.3V digital input from your microcontroller IO, support dual power supply input ensure high anti-interference ability,high reliability of photoelectric isolation protection
3V/3.3V power relay module supports photocoupler isolation control and dual power supply input ensure high anti-interference ability. with diode continuous flow protection,response time is less than 20 milliseconds,long life of relay can be absorbed 100,000 times continuously.
You can select whether the relay and the signal use the same power supply or not by removing the jumper caps on the pins. And It is better to share the same power supply, because that is more convenient for using.
