6pcs 1 Channel DC 3V Relay Power Switch Module with Optocoupler Relay Module Isolated Drive Control Board for ESP8266 Microcontroller Development Board 3V Logic Level Boards
Specification: Channel : 1 channel Control signal: TTL Work voltage: DC 3V/3.3V Compatible Load:10A 250VAC, 10A 30VDC Response time :Less than 20 milliseconds Working Current: 65mA Trigger Current: 3mA Load Current: 10A max Response Time: <20ms The relay module has the output signal indicator light indication The signal input port can connect SCM IO port, high level signal drive Dual power supply design with anti-interference ability and high reliability of photoelectric isolation protection With diode continuous flow protection Response time is less than 20 milliseconds Long life of relay can be absorbed 100,000 times continuously The 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 supply IN: 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 suction COM: common interface of relay NC: normally closed interface of relay, short connection between relay and COM before suction and suspension after suction Package include: 10 x1 channel 3v relay board with optocoupler Note : If you're switching high voltages, be very careful handling this device. The terminal block screws, in particular, are at fully controlled voltages. Turn off all power off before making changes.
Product Features
- Relay module: SRD-DC03V-SL-C; Channel: 1 channel; Operating voltage: DC 3-3.3V; Compatible Load: 10A 250VAC / 10A 30VDC; Single socket length: 7.5mm
- 3V 1-channel relay interface card supports optocoupler isolation control, has the output signal display, the signal input port can connect SCM IO port, high-level signal drive
- The relay board provides a single relay that can be controlled by any 3V/3.3V digital input of your microcontroller IO. Support for dual power supply input ensures high anti-interference ability and high reliability of photoelectric isolation protection
- The 3V/3.3V power relay module supports photocoupler isolation control, and dual power supply input ensures high anti-interference ability . With diode continuous current protection, the response time is less than 20 milliseconds, the long life of the relay can be continuously absorbed 100,000 times.
- You can choose whether the relay and the signal use the same power supply or not by selecting the Remove jumper caps on the pins. And it is better to share the same power supply as it is more convenient for use.
