1. Introduction The Grove-Dry-Reed Relay is a relay module which works through magnetizing the vibration reed via the current in the coils. Compared to electromagnetic relays, the contacts completely sealed is the biggest feature of the Dry-Reed Relay. Besides, it features simplicity in construct, compactness, fast speed and long life, which make it widely applied in many fields such as microelectronic detection, Automatic Control etc.

3. Specification Item Min Typical Max Unit Voltage 4.8 5.0 5.2 VDC Coil Resistance 225 250 275 Ω Pick-Up Voltage 3.75 VDC Switching Current(Max) 0.5 A Switching Voltage(Max) 120 VAC/60VDC - Carrying Current(Max) 1.0 A Operate Time(Max) 1.0 mS Release Time(Max) 0.
4. Usage With Arduino The Dry-Reed Relay can support up to 60VDC 1A load. You can use it to control resistance load, but it is not applicable to inductive load(such as Motor). the usage if this Dry-reed relay is quite alike that of common relays. Connect electric light to Grove - Dry-Reed Relay and power for electric light. Connect Grove - Dry-Reed Relay to port D2 of Grove - Base Shield and plug it into Arduino/Seeeduino. Upload the below code. Please click here if you do not know how to upload.
4.Navigate to the demos' directory: cd yourpath/GrovePi/Software/Python/ To see the code nano grove_relay.py # "Ctrl+x" to exit # import time import grovepi # Connect the Grove Relay to digital port D4 # SIG,NC,VCC,GND relay = 4 grovepi.pinMode(relay,"OUTPUT") while True: try: # switch on for 5 seconds grovepi.digitalWrite(relay,1) print "on" time.sleep(5) # switch off for 5 seconds grovepi.digitalWrite(relay,0) print "off" time.sleep(5) except KeyboardInterrupt: grovepi.
