_ 5V 8-Channel Relay interface board, each one needs 15-20mA Driver Current
_ Relay output maximum contact is AC250V 10A and DC30V 10A
_ Each relay has normally open and normally closed contact. Can be selected by jumper relay and TTL or ground.
_ Standard interface that can be controlled directly by microcontroller (8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic)
_ With power indicator, 8-way road has a status indicator. With a relay coil to absorb the diode protection.
_ Widely used for all MCU control, industrial sector, PLC control, smart home control.
