16 Channel Relay Module Board With Optocoupler Protection For Microcontrollers

Feature: \n 1. Control signal voltage range: The trigger signal is low level 0-2V; the high level voltage cannot exceed 5V.\n2. Adopting the industry's top quality isolated optocoupler, it has strong anti-interference ability and stable performance; the trigger current only needs 3mA.\n3. 1-16 channels can be turned on/off at will, or any way.\n4. Output form: Directly connected to AC 220V 10A or DC30V 10A load.\n5. Each relay common terminal COM is independent, which is convenient for users to access different signals. Each relay has a normally closed and normally open port. \n\nSpecification: \nFeatures:\n\n1.
