16 Channel 5V Mini-Relay Module BK_RL16_01
100 units available with a short lead time.
A compact 16-channel relay module using HUIKE mini-relays, providing optocoupler-isolated control of up to 16 independent circuits. Despite having 16 channels, the board is close in size to a standard 8-channel relay module thanks to the mini-relay form factor.
Each channel has a dedicated LED indicator showing the relay state, and the board includes a power LED. The optocoupler isolation protects your microcontroller circuit from relay switching noise. An elec-blocks socket allows direct relay control using a shunt cap without requiring an MCU.
