About this item
5V 8-Channel Relay interface board, each one needs 70mA Driver Current; Equiped with high-current relay, AC250V 10A ; DC30V 10A
Each relay has normally open and normally closed contact. Can be selected by jumper relay and TTL or ground.
With power indicator,8-way road has a status indicator. With a relay coil to absorb the diode protection.
Standard interface that can be controlled directly by microcontroller (Arduino , 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic)
