Description: Can be high and low bidirectional , support a variety of single-chip, support . Anti-interference ability, the use of diode freewheeling protection. Relay contact part of the use of double-sided thick wiring, for large current through, safe and reliable. Each relay output are led to normally open and normally closed two groups of electric shock, easy to use and flexible. Finished product through 100% functional testing and stability testing. Through the MCU control, can achieve external self-locking mode and non-self-locking two ways to the relay. Specification: Material : Metal, Plastic, Eletric Parts Size(LxWxH): Approx. 148x59x17mm/5.83x2.32x0.67inch Color: Red Available Voltage: 3V,5V,12V,24V Relay Contact Capacity: AC250V 10A DC30V 10A Package Includes: 1 piece Relay Module Board 1 piece Remote Cotroller 1 piece Extension Cord Note: Remote control to be equipped with more than 5V voltage, or remote control can not work well with replay module board.
