2 relay module consists of two LEDs, four resistors, two NPN transistors, two rectifier diodes and two relays that can handle up to 5A 50V AC.
Relays are widely used in remote control, communication, mechatronics, power electronics, etc. They can also be used to control high power voltage/current electronics (such as AC or DC motors, AC devices, etc.).
Particularities
- Thanks to an additional transistor, the module can be switched with most microcontrollers with little current.
- Equipped with transistors, diodes and optocouplers, the module switches higher loads safely and reliably.
- Generously dimensioned to allow permanent operation even under unfavorable operating conditions.
