ℹ
Products from the USA may come with an input voltage of 110V–120V, requiring a step-down transformer. Check the device wattage to select the correct power converter.
•【Product】5V 8-Channel Relay interface board, each one needs 15-20mA Driver Current; Equipped with high-current relay, AC250V 10A ; DC30V 10A.
•【Contacts Independently】Each relay has normally open and normally closed contact. Can be selected by jumper relay and TTL or ground.
•【Indicator】With power indicator, 8-way road has a status indicator. With a relay coil to absorb the diode protection.
•【Standard Interface】Can be controlled directly by microcontroller ( 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic).
•【Application】8 Channel DC 5V Relay Module Board widely used for all MCU control, industrial sector, PLC control, smart home control. The 8 channels are optically isolated, safe, reliable, anti-interference.
