12V 16-Channel Optocoupler Relay Board Module LM2576 Power Supply

• 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 a 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.

Specifications:

Instructions

• The power supply should meet the scope of use, DC 5V.
• The power supply cannot be reversed.
• The product uses LM2596S step-down chip with slight heat, which is a normal phenomenon. The relay has normal heating phenomenon for a long time, which is a normal phenomenon.
• The load power should have a certain margin for the relay load. Avoid high power (about 2000W) and work for a long time, which will have a certain impact on product life.

Applications:

• Electromagnetic relays are employed for the protection of various ac and dc equipments.
• The over/under current and voltage protection of various ac and dc equipments.
• For differential protection.
• Device switching.
• Multiple DIY projects.

Package Includes

• 1 x 16-Channel 12V Relay Module Board W/ Power LM2576 / Optocoupler Protection
