12V 8 Channel Relay board This 12V 8 Channel Relay board meets the safety standard as control areas and load areas have the isolation groove. Optical coupling isolation module. The triggering of the 8-Channel Relay Module is reliable and more stable. The double FR4 circuit board design is a high-end SMT process. It has power and relay operation instructions. Relays terminals (C, NC, NO) are accessible through screw terminals which makes wiring up the board very easy. The inputs of the 8 Channel 12V Relay Module are isolated to protect any delicate control circuitry. A wide range of microcontrollers such as Arduino, AVR, PIC, ARM, and so on can control it. The use of such a high-voltage relay eliminates the risk of heating up the relay as electromechanical relays limit the current consumption in accordance with a voltage rating.

Also check 12V 16 Channel Relay Module with Light Coupling LM2576 Power Supply, suitable for controlling various appliances and equipment with a large current. It can be directly controlled by microcontrollers such as Arduino, 8051, AVR, PIC, DSP, ARM, MSP430, and TTL logic. Each relay on the board requires 15-20mA Driver Current, and there is an indication LED for Relay output status. The module features light coupling protection (optocoupler) for the isolation of control circuitry.
