This item is a 5V 8-Channel Relay interface board,It can be controlled directly by microcontrollers such as Arduino, AVR, PIC, ARM and so on.
- Each relay needs 15-20mA driver current.
- Equiped with high-current relay : DC30V 10A AC250V 10A.
- Each relay has normally open and normally closed contact.
- The 8 channels are optically isolated, safe, reliable, anti-interference.
- Can be selected by jumper relay and TTL or ground.
- With power indicator,each channel has a status indicator.
- With a relay coil to absorb the diode protection
- Size: 140mm X 55mm
- 1 x 8 channel relay module
