Rajguru Electronics presents a powerful and versatile 12V 16-Channel Relay Module with Light Coupling, coupled with an efficient LM2576 Power Supply. This module offers you the capability to control a wide range of appliances and high-current equipment, making it an ideal choice for various applications. It seamlessly interfaces with microcontrollers like Arduino, 8051, AVR, PIC, DSP, ARM, MSP430, and TTL logic.
This 12V 16-Channel Relay interface board requires a mere 15-20mA Driver Current for each individual relay. It incorporates LED indicators to provide real-time feedback on the status of relay outputs, enhancing user convenience. The module features a standard interface that allows direct integration with popular microcontrollers such as Arduino, ensuring ease of use.
Notably, our relay module employs 12V electromechanical relays with an AC contact capacity of 250V. It also includes light coupling protection (optocoupler) for isolating the control circuitry, enhancing safety and reliability. Importantly, this module doesn't require an external power supply, as it offers plate load power support, making it compatible with various Single Chip Microcontrollers (SCM).
Furthermore, the LM2596S buck chip within this relay module may exhibit slight heating during operation, which is a normal characteristic shared with relays that undergo long hours of operation. It's worth noting that for optimal product longevity, it's advisable to maintain a moderate relay load power and avoid high-power (approximately 2000W) and extended operational durations, as this can impact the product's overall lifespan.

Functional Discription :16 Channel Relay module 12V
- • A relay is an electrically operated device. It has a control system and (also called input circuit or input contactor) and controlled system (also called output circuit or output contactor). It is frequently used in an automatic control circuit. To put it simply, it is an automatic switch to controlling a high-current circuit with a low-current signal.
- • The advantages of a relay lie in its lower inertia of the moving, stability, longterm reliability and small volume. It is widely adopted in devices of power protection, automation technology, sport, remote control, reconnaissance, and communication, as well as in devices of electromechanics and power electronics. Generally speaking, a relay contains an induction part which can reflect input variable like current, voltage, power, resistance, frequency, temperature, pressure, speed and light etc. It also contains an actuator module (output) which can energize or de-energize the connection of the controlled circuit. There is an intermediary part between the input part and output part that is used to coupling and isolate input current, as well as actuate the output. When the rated value of the input (voltage, current and temperature etc.) is above the critical value, the controlled output circuit of the relay will be energized or de-energized.
