This is a high-performance relay module, which is practical and convenient for users. Features: Module voltage: 5V, 12V, 24V are available. Output capacity: 30V 30A DC or 30A 250V AC. Using optocoupler isolation, strong anti-jamming ability and stable performance. The module can be set to high or low trigger. With power indicator and work indicator. To ensure stability, uses industrial-grade PCB and 9.5mm barrier terminals. All interfaces can be connected directly via terminal wiring wires, very convenient. Interface Module Description: 1. DC +: DC power supply positive; 2. DC -: DC power supply module negative; 3. IN: Signal input terminal (support high / low level switch freely); 4. Normally open (NO): The relay normally open; 5. Common terminal (COM): Relay common terminal; 6. Normally closed (NC) terminal: Relay normally closed terminal; Features: Type: 1-channel / 2-channel (optional) Relay voltage: 5V / 12V / 24V (optional) Output capacity: DC 30V 30A or 30A 250V AC Quiescent: 5mA Maximum current: 5V: 190mA; 12V: 80mA; 24V: 50mA Trigger Current: 5mA Module Size: 1 Channel: 66 * 40 * 22mm; 2 Channel: 69 * 66 * 22mm Module Weight: 1 Channel: 47g; 2 Channel: 90g Package List: 1 * Relay Module
