12V 16 Channel Relay Module with Light Coupling LM2576 Power Supply

This 12V 16 Channel Relay Module with Light Coupling LM2576 Power Supply can regulate a wide range of appliances and high-current devices. Micro-controllers (Arduino, 8051, AVR, PIC, DSP, ARM, MSP430, TTL logic) can be used to directly control it.

The 12V 16-Channel Relay interface board requires 15-20mA of driver current for each individual relay. The board has an LED indicator for the state of the relay output and a standard interface that many commonly used microcontrollers, such as Arduino, etc., may control directly.

The 12-volt electromechanical relay module has a 250-volt AC contact capacity and an optocoupler for light coupling protection to isolate the control circuitry. An external power source is not required for the plate load power module. All SCM Drives are supported.

This relay module’s LM2596S buck chip exhibits a mild temperature, which is typical for relays because they typically experience fever during extended workdays. 4 relay load power to allow for wiggle room; steer clear of high-power (about 2000W) and extended operating environments as these will shorten the product’s lifespan.

Note: Brand of Relay (Songle, Bestep, etc.) May vary from the picture shown according to the availability from the supplier. Please note it before placing the order.

Features :

• 12V relay with AC contact capacity of 10A 250V and optocoupler protection.
• Onboard power supply module does not need an external power supply. I / O port driver is active low.
• The module can be used as microcontroller development board module and also as appliance control, PLC extended output.
• It is using the industry’s top -quality isolation optocouplers, strong anti-jamming ability, stable performance.
• The 1-16 road can be any full on/off or any road.
• Each relay common terminal “COM” are independent, user-friendly access to different signals, each relay are normally closed and normally open with the port.
• Each relay is equipped with motion lights.
• All interfaces can be directly connected through the terminal leads, very convenient.
