Description
This 8-channel Relay module comes with Optocoupler protection is an active low relay module which means that the relay will conduct when the input signal falls below 2V and if it is above 2V then the relay is turned off you can also make it an active module by changing the jumper position on the power module. It can be controlled directly with both 3.3V and 5V microcontrollers easily. You can use it to control both DC and AC lines and it also has LED indicators to indicate the state of operation of the module. It also has high Impedance input pin so not to draw any more current than required from the controller. Optically Isolated relays protect your microcontroller from damage if the equipment being controlled fails
Features:
- 5V 8-Channel Relay Interface Board, each one needs 15 – 20mA Driver current
- Equipped with high current relays 10A which can handle upto 250VAC
- Contact some independent wiring , safe and reliable
- Standard interface , can be extended in a variety of development board
- With fixed screw holes for easy installation
- Suitable for a variety of platforms such as 51/AVR/AVR/ARM
- Using double-sided FR-4 circuit board design, high-end chip production process
- The signal input has a low signal , often beginning with a common terminal will be turned on
- 8 normally open and 8 normally closed contacts
- Blue KF301 terminals to the control line is more convenient.
