These single Channel 24V Relay Modules offer a 30AMP switching current at up to 240V AC or up to 30V DC, but are controlled with a common 24V DC coil voltage.
This is a 30A 12V Power Relay Module With Optocoupler Isolation H/L Level Trigger: it can be controlled directly by a wide range of microcontrollers such as 8051, AVR, PIC, ARM, DSP and so on.
