A relay is an electrically operated switch having a set of input terminals for a single or multiple control signals, and a set of operating contact terminals. This is a 4 channel relay module by MAG BEE which can be used to activate up to 250V AC and 30V DC. Power indicator: Green | Relay status indicator: Red | 8550 transistor-driven | Strong driving ability | Fixed bolt hole | Easy installation | Diode effusion protection | Short response time | Board mode selection | Real-time working status indicator This 4 -channel relay module can be used to control various appliances, and other equipments with large current. It is ideally suited to control larger voltages in your project through Wi-Fi. 4-channel Relay Module: Operating Voltage (VDC):2.5~5.5 | Trigger Voltage (VDC):5 | Trigger Current (mA):20 | Switching Voltage (VAC):250@10A | Switching Voltage (VDC):30@10A | Operating Temperature (°C):-40 to 85 | Storage condition (?):-65 to 125 | Transmission Distance:400m (max.)
