Description: The module uses real high quality 30A relay. The maximum load of normal interface is 250V/30A AC, 30V/30A DC. Chip optocoupler isolation, strong driving ability, stable performance, trigger current 5mA; Module working voltage 5V Module can be set up by high jump or low level trigger. Humanized interface design, all interfaces can be directly connected through the terminal, very convenient. Specification: Technical parameters: Relay version static current maximum current triggered current 5V 5mA 190mA 2-4mA 12V 5mA 80mA 2-4mA 24V 5mA 50mA 2-4mA Module interface description: DC+: module DC power supply positive pole (trigger terminal voltage positive). DC-: module DC supply negative pole (trigger terminal voltage negative). IN: signal triggering terminal (default trigger voltage is the same as power supply). Selection of high/low level trigger mode. For example, when jumper is connected to L-terminal, IN-terminal is low level trigger, while H-terminal is high level trigger. Normally closed end (NC): normally closed relay. Public terminal (COM): common end of relay Often start (NO): relay normally open. Module size: 70x72x22 mm / 2.75x2.83x0.86 inch Package Includes: 1 piece 2 way 30A high and low level trigger relay module
