The Okdo TelePort relay is an "automatic switch" that uses a small current to control a large current. In daily life, we generally use AC power supply to drive electrical equipment, and sometimes we use switches to control electrical appliances. If the switch is directly connected to a AC circuit, people will be in danger once there is a electricity leakage. Therefore, we design this relay module with NO (normally open) and NC (normally closed) terminals.
Capable of switching a maximum load of AC 250V/10A, DC 30V/10A with a Normally Open (NO) relay Low 5mA trigger current, strong drive capability and stable performance
