Relay Module 16 channels 12V with LM2576

The 16 Relay Opto circuit isolating is used to control switching devices through 16 Relay, the main source of the circuit is 12VDC which is used to feed the relay and power the impulse reducing circuit to create a 5VDC source for Microcontroller. , Opto isolator integrated circuit and anti-jamming IC buffer ensure the system is always stable.

Note 5VDC pin on the circuit is the output pin generated from the pulse relief circuit on the circuit, this pin is only used to power, if not in use please leave it blank.
