Specification: _x005f_x000D_ Origin: Mainland China _x005f_x000D_ Type: Module _x005f_x000D_ Condition: New _x005f_x000D_ Model Number: Relay Module Board _x005f_x000D_ Product Name: Relay Module _x005f_x000D_ Optional: 1 way 5V, 1 way 12V, 1 way 24V, _x005f_x000D_            2-way 5V, 2-way 12V, 2-way 24V, _x005f_x000D_            4-way 5V, 4-way 12V, 4-way 24V, _x005f_x000D_            8-way 5V, 8-way 12V, 8-way 24V (optional) _x005f_x000D_ Module size: 50x 26x18.5mm/1.96x1.02x0.72inch _x005f_x000D_ Module interface: _x005f_x000D_ 1. DC+: Connect to the positive power supply (the voltage depends on the requirements of the relay, there are 5V, 12V and 24V options) _x005f_x000D_ 2. DC-: connected to the power negative _x005f_x000D_ 3. IN: High or low level can control the relay pull-in _x005f_x000D_ Relay output: _x005f_x000D_ 1. NO: The relay is normally open interface, the relay is suspended before the pull-in, and it is short-circuited with COM after the pull-in _x005f_x000D_ 2. COM: Relay public interface _x005f_x000D_ 3. NC: The normally closed interface of the relay, the relay is shorted with COM before the relay is pulled in, and it is suspended after the pull-in _x005f_x000D_ High and low level trigger selection terminal: _x005f_x000D_ 1. When the jumper is short-circuited with LOW, it is a low-level trigger; _x005f_x000D_ 2. When the jumper is short-circuited with high, it is a high-level trigger. _x005f_x000D_ Technical Parameters: _x005f_x000D_ Relay Version Quiescent Current High Current Trigger Current Trigger Voltage (Low) High _x005f_x000D_    5V 5mA 190mA 2-4mA 0-1.5V 2.5-5V _x005f_x000D_    12V 5mA 80mA 2-4mA 0-4V 4.5-12V _x005f_x000D_    24V 5mA 50mA 2-4mA 0-8V 8.5-24V _x005f_x000D_ _x005f_x000D_ _x005f_x000D_ _x005f_x000D_ Note: _x005f_x000D_ Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures.
