ARCELI 6Pcs 5V One 1 Channel Relay Board Shield with Optocoupler Support High and Low Shooting Power Supply Module for Arduino

• The module uses genuine quality relay, normally open interfaces Maximum load: AC 250V / 10A, DC 30V / 10A
• 1-channel relay module, with photoelectric isolation; relay action and power indicator
• Operating voltage module 5V
• The module can be high or low using a bridge configuration trigger
• Module size: (L x W x H) 50 mm x 26 mm x 18.5 mm

Module description: 1. Using SMD optocoupler insulation, driving capacity, stable performance; 5mA firing current; 2. Failure tolerant design, even if the control line is broken, the relay will not work; 3. Power indicator (green), relay status indicator (red) 4. Human nature interface design, all interfaces are available through a direct connection terminal, very convenient 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 Shooting Options: It is a low-level trigger when the bridge connects to the LOW pin It is a high-level trigger when the bridge connects to the HIGH pin Package includes: Relay Module 6x
