DC 12V 12-Channel 10A Relay Control Module Low Level Trigger Red and Blue Indicators for Arduino

1, The module uses genuine high quality relay, normally open interface maximum load: AC 250V / 10A, DC 30V / 10A;
2, Using high-power high-voltage transistor 2907A, strong driving capability, stable performance; trigger current 5mA;
3, Module working voltage DC 12V;
4, The relay pull-low, the module contains a current-limiting resistor, low-level can be DC-, microcontroller I / O port can also be set low; 5, Fault-tolerant design, even if the control line is broken, the relay will not move;
6, Power indicator (red), 12 relay status indicator (blue);
7, User-friendly interface design, all interfaces can be directly connected leads, very convenient;
8, Module size: 12mm x 9mm x 18mm / 4.72 x 3.54 x 0.71 inch (L * W * H);
9, Weight: 39 g / 0.086lb;
10, With 4 fixing bolt holes for easy installation.

Module interface
Module control side:
