Sherlotronics relay board

• Full bridge rectification so you can use AC/DC
• LED indication
• Normally Open
• Normally Closed
• Potentially Free Common contact.

Sherlotronics relay board  is an electrical switch that is operated by an electromagnet. The electromagnet is activated by a separate low-power signal from a micro controller. When activated, the electromagnet pulls to either open or close an electrical circuit.

Relay boards are computer boards with an array of relays and switches. They have input and output terminals and are designed to control the voltage supply. Relay boards provide independently programmable, real-time control for each of several onboard relay channels.

Sherlotronics relay board is commonly used in various electrical and electronic applications to perform tasks such as switching high-voltage loads with a low-voltage control signal, amplifying weak signals, providing isolation between circuits, and allowing for the automation of complex processes.

• User-friendly interface design, all interfaces are available through the wiring terminal direct connection leads, very convenient.
• MD optocoupler isolation, driving ability, stable performance; trigger current 5mA;
• Authentic quality module 30A relay, normally open interfaces Maximum load: AC 250V / 30A, DC 30V / 30A;
• The module uses genuine quality relay, normally open interfaces , Maximum load: AC 250V/10A, DC 30V/10A.
• Using SMD optocoupler isolation, strong driving capability, stable performance; trigger current 5mA.
• Fault-tolerant design, even if the control line is broken, the relay will not move.
• The interface design of human nature, all interfaces are available through a direct connection terminal leads, very convenient.
• The Module can be set by jumper high or low trigger.
