OCTOPUS 1-Channel Relay is a single relay electronic brick:
Note:
Module 5V power supply:
Never use power supply more than 5V, which may cause damage to the module.
Features:
Relay Power Supply Voltage:<V
Relay drive level:
With opto-isolation circuit, can completely isolate the relay controlling signal and the controlled signal, secure and dependable
Contactor control:
Indicator:
Drive circuit: Transistor drive circuit, controlling pin high impedance, and requiring very small drive current, about 5mA
Pulldown relay controlling signal to prevent false triggering
Using high-current relay, DC 24V 2A, AC 120V 2A
PCB positioning holes: 3mm standard positioning holes, can install 3mm standard studs, screws
Applications:
Smart home
Industrial control
Equipment remodel
Motor Control

Jargon buster
Plain-language definitions for the technical terms used above.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- Impedance
- Impedance is the total opposition a component or circuit presents to alternating current, measured in ohms, combining resistance with frequency-dependent reactance. It appears in many contexts, such as matching a speaker's impedance (for example 4 ohm or 8 ohm) to an amplifier or the input and output impedance of signal circuits, and a correct match helps avoid weak signals, distortion or damage.
- PCB
- A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
