Feature

Bidirectional isolation 2-Channel high-power relay control module, select the high or low signal trigger, only need 3mA current can drive control capability of 30A relay pull.
The module uses high-quality power relay, ultra-small package optocoupler, high-power high-voltage transistor, red and blue signal indicator, double-sided PCB board, cloth board to consider a comprehensive, stable performance can be widely used in a variety of power control The Module operating voltage 5V, 12V, 24V to choose from;
The user can select the relay control level, can be high level pull, it can be low level pull; module with current limiting resistor, you can directly use the power supply positive and negative control, you can also use the microcontroller I / O Mouth control
The module uses high-quality relay, normally open interface Maximum load: AC 250V / 30A, DC 30V / 30A;
Fault-tolerant design, even if the control line is broken, the relay will not work;
