## 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. 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. Key Features 16 Independent Channels – Each with optocoupler isolation and LED status indicator Compact Design – Ultra-small volume, close to the size of an 8-channel module Optocoupler Isolation – Protects your microcontroller from switching noise 5V/12V TTL Control – Compatible with Arduino, Raspberry Pi, PIC, ARM, and MSP430 Elec-Blocks Socket – Direct relay control via shunt cap (no MCU required) Specifications Drive Voltage – 5V / 12V Drive Current – 20 mA per channel Control Signal – 5V/12V TTL level Max Switching Voltage – 150VAC / 24VDC Max Switching Current – 2A Relay Type – HUIKE mini-relay Indicators – Power LED + 16× channel LEDs Mounting Holes – 3 mm Dimensions – 85 × 72 mm PCB Colour – White Warning: This module switches mains-level voltages (up to 150VAC). Ensure all high-voltage wiring is performed by a qualified person and meets local electrical regulations. Ideal For Home automation and lighting control Multi-channel equipment switching Arduino and microcontroller relay projects IoT control panels Package Contents 1× 16-channel mini-relay module (BK_RL16_01)
