Beschreibung
Our relay modules switch quickly and reliably many switching operations. Thanks to an additional transistor, the module can be switched with most microcontrollers with little current. The relays used are generously dimensioned to allow permanent operation even under unfavorable operating conditions.
The optocouplers and diodes protect your controller from damage. The source of the power supply can be configured with a jumper located on the board.
The relays are commonly used in remote control, communications, mechatronics, power electronics, etc. They can also be used to isolate high power voltage/current electronics (such as AC or DC motors, AC devices, etc.) from microelectronics (microcontrollers, sensors, etc.).
Particularities
- Generously dimensioned to allow permanent operation even under unfavorable operating conditions.
- Thanks to an additional transistor, the module can be switched with most microcontrollers with low current.
- Compact design and large capacity: this 8-relay module can switch high currents up to 5A.
