Application: 1,12V relay contact capacity 10A 250V, with optocoupler protection. The onboard power supply module does not require an external power supply. I / O port is active low. 2, can be used as a single-chip development board module, can be used as home appliances control, can also be used as PLC expansion output. Module Features: 1, the control signal voltage range: the trigger signal is low 0-2V; high voltage can not exceed 5V. 2, using the industry's top quality isolation optocoupler, anti-interference ability, stable performance; trigger current only 3mA. 3, 1-16 way can be all open / close, or any way. 4, the output form: directly AC 220V 10A or DC30V 10A load. 5, each relay common COM are independent, user-friendly access to different signals, each relay with a normally closed and normally open port. 6, each relay with action lights, pull up bright, off off. 7, user interface design, all interfaces can be directly connected through the terminal leads, very convenient. 8, with four fixed bolt holes, easy to install. 9, PCB board size: 180MM (L) * 90MM (W) * 20MM (H). Electrical parameters: Supply voltage: 5V 12V (DC) Supply current: greater than 200mA Each relay can be loaded: 250V 10A (AC) or 30V 10A (DC) product manual: 1. Power supply to meet the scope of use, DC 12V; 2. Power supply according to the wiring diagram requirements, can not be reversed; 3. Product use LM2596S buck chip slightly fever, is a normal phenomenon, the relay work for a long time there are normal fever, are normal phenomenon; 4. Load power to the relay load to leave a certain margin, should avoid high-power (2000W or so) and long hours of work environment, the product life will have a certain impact. Shipping list: 16 relay modules *1
