Relay Shield v3.0 4CH Channel Large Relay Expansion Board

Feature The Relay Shield provides four high quality relays that can control high current loads to ARDUIN0 Seeeduino boards It also provides NO Normally Open NC Normally Closed interface It could be a nice solution for controlling devices that could not be directly controlled by Digital I Os The standardized shield form factor enables a smooth connection The shield also has four LED indicators to show the on off state of each relay Relays are useful in switching on off AC appliances like fan light motor or high current DC actuators like solenoid valve etc Specification Uno Leonardo Seeeduino compatible Other board or microcontroller via jumper cables Interface via digital I O pins 4 5 6 and 7Relay screw terminalsStandardized shield shape and designLED working status indicators for each relayHigh quality relaysCOM NO Normally Open and NC Normally Closed relay pins for each relayUpdate pin SCL SDA IOREF NC Dimensions100mm x67mm x30mmWeightG W 77gBatteryExcludeOperating Voltage4 75V 5 25VOperating Current 8 250 mASwitching Voltage 250VAC 30VDCSwitching Current 15A 7AFrequency 1HzSwitching Power 70WRelay Life 100 000 CycleESD contact discharge ±4KVESD air discharge ±8Dimension 68 7 x 53 5 x 30 8 mmNet Weight 55±2 gDocumentations Relay Shield v3 0 Eagle FilewikiPackage includes 1 x Relay Shield v3 0
