5V DC SSR Relay Module Low Level Relay For Arduino

A solid state relay (SSR) is an electronic switching device that switches on or off when an external voltage (DC) is applied across its control terminalsThis is a 5V low level trigger 2/4/8-channel relay interface board that can be used to control various appliances and equipment with current consumption of up to 2A. It has a standard interface that can be controlled directly by microcontrollers like Arduino, Raspberry PI e.t.c . Each channel needs a 15-20mA driver current. It is optically isolated from high voltage side for safety requirement and also prevent ground loop when interfaced to a microcontroller. It serves the same function as an electromechanical relay, but has no moving parts and therefore results in a longer operational lifetime.

Features:

• This 8 channel 5V relay has both optical and magnetic isolation, providing a lot of protection to the inputs from electrical faults on the outputs.
• Works well with both 3.3V and 5V logic (Raspberry Pi, Arduino, Teensy..), requiring little current drive.
• Breadboard friendly, using female/male links makes it extremely convenient for prototyping.
• LED indicates its working status. Red refers to errors.
• 2 Terminals AC only as the output 2 Amps Max.
• Input voltage level support TTL as well as CMOS
