This M5Stack 4-Relay Unit is an integrated 4-way relay module that will help you set up such projects as digital signal switching or creating a programmable power switch. The maximum control voltage of each relay is AC-250V/DC-28V, the rated current is 10A, and the instantaneous current can hold up to 16A. It’s super convenient to use, as each relay can be controlled independently by the I2C communication protocol. In addition to this, each relay has a status LED indicator that displays the state of the relay.
