SONGLE SRD-12VDC-SL-C relay 240V 10A, 12V DC actuated, NC/NO contact

SONGLE SRD-12VDC-SL-C relay 240V 10A, 12V DC actuated, NC/NO contact

The SONGLE SRD-12VDC-SL-C relay is a reliable output device for electronic projects built around microcontrollers powered at 12V (ideal for Arduino, Raspberry Pi, ESP8266, and ESP32). It provides COL1, COL2, and COM outputs for safe, efficient switching of circuits with a maximum load of 10A at 250V AC or 30V DC.

Its compact 19.6 x 15.4 x 15.5 mm footprint integrates easily into professional and hobbyist setups. With 5 pins and a NC/NO changeover contact, it offers stable operation with very low coil power consumption of just 0.36 W. It is an excellent choice for switching electrical and electronic loads with higher current draw.
