DFRobot DFR0017 Gravity: Digital 5A Relay Module

The DFRobot Relay Module is a standard relay used with a controller board tointerface external electrical circuits or modules. Some of the most commonapplications with Arduino are Home lighting, electrical appliances of high powerand other equipment. The modular design makes it easy to integrate with acontroller board. The Relay integrates a status LED, in order to acknowledgevisually it's status On or off. It can be controlled through the digital IOport, with a simple High or Low on Arduino compatible boards. Other boards willwork requiring the same voltage level. Other usages include control of solenoidvalves, lamps, motors and other high current or high voltage devices.Latest Update: V3.1Improved the silkscreen on the bottom layer of the sensor to indicate thehardware connection.Some kits may include acrylic holder and nylon screw set to prevent shorting ofhigh power interface with a metallic surface.Specifications:- Single relay board- Rated through-current: 10A (NO) 5A (NC)- Maximum switching voltage: 150VAC 24VDC- Interface: Digital- Control signal: TTL level- Contact Rating (Res.
