The standard 1 Channel 12v 30A Opto Isolated Relay Module, using of High-level voltage signals to trigger, only needs 3mA current signal to drive the 30A load relay. Use of high-quality power relay, high-withstand voltage transistor, red & green signal lights assures accurate and stable performance. Can be used in various types of power control occasions.
1. Using of high-quality relay, normally open relay contacts maximum load: AC 0--250V/30A, DC 0-- 30V/30A; 2. Using of high-withstand voltage transistor, strong driving ability, stable performance, trigger current of 3mA; 3.Working voltage:12V
4. The relay using of high-level voltage signals to trigger, high-level voltage signals can be DC power supply positive, also can be microcontroller I/O port set high; 5. The power indicator (red LED), relay status indicator (Green LED);
The relay module outputs(3-wire interface with terminal blocks, very convenient) 1.NO: the relay normally open contacts; 2.COM: the Relay common contact; 3.NC: the relay normally closed contacts.
