Specification

the module uses genuine high-quality relay, normally open interface Maximum load: AC 250V/10A, DC 30V/10A;
high-power high-voltage transistor 2907A, driving ability, stable performance; trigger current of 5mA;
the relay low pull the module with limited flow resistance, low GND, microcontroller I / O port is set low;
fault-tolerant design, even if the control line is broken, the relay will not operate;
the power indicator (red), 8-way relay status indicator
interface design, user-friendly, all interfaces can be drawn through terminals connect directly, very convenient
module size: 7.9cm * 9.0m * 1.8cm (L * W * H)
has four fixed bolt hole for easy installation

Standard 8-channel relay control module, the use of genuine high-quality power relays, high-power high-voltage transistors, red, blue signal lights, military grade double-sided PCB board, cloth board to consider a comprehensive, stable performance, can be widely used in a variety of powercontrol the types of occasions.

Module control terminal: 10-wire interface, all interfaces can be directly connected to leads, user-friendly

VCC: external 12V
GND: external ground
CL1-CL8: relay control interface, low level corresponding relay

Relay outputs: 24-wire interface, all interfaces can be directly connected to leads, user-friendly

NO1 - NO8: relay normally open interface, the relay becomes vacant before the pull shorted with COM
COM1 - COM8: public interface relay
NC1 - NC8: relay normally closed interface, the relay shorted together with COM, pull vacant
