5V 1 Channel H/L Level Trigger Optocoupler Relay Module For Arduino
We have ✅ 41 available of the LB-LR0046 in our Sydney warehouse.
The 5V 1-Channel Optocoupler Relay Module provides safe, isolated switching of high-voltage loads from a microcontroller. An onboard SMD optocoupler isolates the control circuit from the relay, protecting your Arduino, Raspberry Pi, or other development board from voltage spikes.
A jumper setting lets you select either high-level or low-level trigger, giving you flexibility to match your project's logic. A fault-tolerant design ensures the relay remains off if the control line is disconnected.
Key Features
- Optocoupler Isolation – SMD optocoupler separates control and load circuits for safety
- Selectable Trigger Level – Jumper to choose high or low level trigger
