SainSmart 4-Channel 5V Relay Module

5V 4-Channel Relay interface board, and each one needs 15-20mA Driver Current

– Equiped with high-current relay, AC250V 10A ; DC30V 10A.

– Standard interface that can be controlled directly by microcontroller (Arduino , 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic active low).

– Opto-isolated inputs.

– Indication LED’s for Relay output status.
