4 way 5V relay module for Arduino
RM4
5V relay module for Arduino and other microcontroller projects
This module has 4 x 5V changover relays with the option of using them through optocouplers. There is an LED for each relay to indicate when it has been activated.
The relay allows the low current microprocessor outputs to switch higher currents and voltages. With the optocouplers it fully isolates the live side of the relays from your microprocessor, this will require a seperate 5V supply to power the relays.
Trigger voltage : 5VDC
Supply Voltage : 5VDC (only needed if using optoisolators)
AC Switch ratings : 250V 10A
DC Switch ratings : 30V 10A
Size 73x52mm
