4pcs 12V 1 Channel Relay Module Board with Optocoupler Isolation, High and Low Level Trigger, 10A Relay Control for Arduino, MCU, and DIY Automation

Description

Product description Module Description 1. The module uses genuine quality relay, normally open interfaces Maximum load: AC 250V/10A, DC 30V/10A; 2. Using SMD optocoupler isolation, driving ability, stable performance; trigger current 5mA; 3. The module Operating voltage 5V/12V/24V; 4. The module can be high or low by a jumper setting trigger; 5. Fault-tolerant design, even if the control line is broken, the relay will not operate; 6. The power indicator (green), the relay status indicator (red) 7. The interface design of human nature, all interfaces are available through a direct connection terminal leads, very convenient 8. Module size: 50mm*26mm*18.5mm (L*W*H) Oiyagai 4pcs 5V/12V/24V One 1 Channel Relay Module Board Shield with optocoupler Support High and Low Level Trigger Module interface 1. DC+: Positive power supply (VCC) 2. DC-: Negative power supply (GND) 3. IN: Can be high or low level control relay Relay outputs 1. NO: Normally open relay interface 2. COM: Common Interface Relays 3. NC: Normally closed relay interface High and low level trigger options It is low level trigger when jumper connect to LOW pin It is high level trigger when jumper connect to HIGH pin Package Include: 4 x relay module Review: Relays in 12vdc projects. - Used the 12vdc relays for my 12vdc charging project. One for the charging and other to cutoff the load during charging. In a different 12vdc project used a lm358 circuit to triggering the relay in a over voltage cutoff which would cutoff it main 12vdc supply so it could not restart. Review: Works great - Got them right on time, it does the job perfectly well.
