One-Channel Single-channel 12V 30A Relay Module

Information:

The standard 1-channel relay control module, using of High-level or Low-level voltage signals to trigger, only need 3mA current signal to drive the 30A load relay. And using of high-quality power relay, high-withstand voltage transistor, red & blue signal lights, Double-sided PCB layout, layout considerations accurate and stable performance, Widely used in various types of power control occasions.

Details:

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 DC
4/ The relay using of high-level voltage signals to trigger ,the module contain limited flow resistance, high-level voltage signals can be DC power supply positive, also can be microcontroller I/O port set high;
5/ Fault-tolerant design, if the control line is broken, the relay will not operate;
6/ The power indicator (red LED), 1-channel relay status indicator (blue LED);
7/ The interface humanization design, all interfaces can be drawn through terminals connect directly, very convenient;
8/ The module size: 6.0cm (L) * 3.0cm (W) * 2.5cm (H);
9/ With has four fixed bolt holes for easy installation.

Relay Module Reference:

The module control terminal: 3-wire interface, all interfaces have terminal blocks, very convenient.
1. DC+: external DC power positive electrode
2. DC-: external DC power negative electrode
3. CH1: relay control interface, high level corresponding relay pull.

The relay module outputs: 3-wire interface, all interfaces have terminal blocks, very convenient.
1. NO: the relay normally open contacts;
2. COM: the Relay common contact;
3. NC: the relay normally closed contacts.
