{"title":"16 Channel 5V Mini-Relay Module BK_RL16_01","handle":"16-channel-5v-mini-relay-module-bk_rl16_01","url":"/products/16-channel-5v-mini-relay-module-bk_rl16_01","description":"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.\n\nEach 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.\n\nKey Features\n\n\n16 Independent Channels – Each with optocoupler isolation and LED status indicator\n\nCompact Design – Ultra-small volume, close to the size of an 8-channel module\n\nOptocoupler Isolation – Protects your microcontroller from switching noise\n\n5V/12V TTL Control – Compatible with Arduino, Raspberry Pi, PIC, ARM, and MSP430\n\nElec-Blocks Socket – Direct relay control via shunt cap (no MCU required)\n\n\nSpecifications\n\n\nDrive Voltage – 5V / 12V\n\nDrive Current – 20 mA per channel\n\nControl Signal – 5V/12V TTL level\n\nMax Switching Voltage – 150VAC / 24VDC\n\nMax Switching Current – 2A\n\nRelay Type – HUIKE mini-relay\n\nIndicators – Power LED + 16× channel LEDs\n\nMounting Holes – 3 mm\n\nDimensions – 85 × 72 mm\n\nPCB Colour – White\n\n\n\nWarning: This module switches mains-level voltages (up to 150VAC).
