10 PCS HW-482 5V Relay Module Arduino Board

Overview & Features

. 5V relay module. It can be used as a single-chip development board module, and can be used as a home appliance control. 5V-12V TTL control signal. Control DC or AC signal, can control 220V AC load. There is a normally open and a normally closed contact. Has a power indicator. There is a control indicator light, which is bright when closing, but not bright when disconnecting. Transistor drive increases the relay coil, and the control pin is high impedance. The control pin has a pull-down circuit to prevent the false action of the floating relay..
