24V 4 channel relay module with light coupling
This is a 4 channel 24V relay module with light coupling. This board is manufactured from a new and advanced design with high-end SMT processors. The terminals (C, NC, NO) are accessible through screw terminals which makes wiring up the board very easy. The relay is safely driven by transistor BC547 hence your input device, such as Arduino, is secure from the relay circuit. The inputs of this 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 an electromechanical relay limits the current consumption in accordance with a voltage rating.
- Equipped with high-current relay
- It can control both AC and DC appliances such as Motors, lights, fans, etc.
- High-quality screw terminals
- Freewheeling diode to protect your microcontroller
