Specification

1, the module using genuine quality relay, normally open interface Maximum load: AC 250V/10A, DC 30V/10A;
2, using high-power high-voltage transistor 2907A, driving ability, stable performance; trigger current of 5mA;
3, Module operating voltage 12V
4, relay low level pull, the module containing the current limiting resistor, low level can GND, MCU I / O port is set low;
5, fault-tolerant design, even if the control line is off, the relay will not operate;
6, power indicator (red), 4-way relay status indicator (blue);
7, interface design user-friendly, all interfaces can connect directly leads to very convenient;
8, module size: 7.5cm * 5.0cm * 1.8cm (L * W * H);
9, There are four fixed bolt hole for easy installation;

Working voltage: DC 5V, 12V, 24V version,(should not exceed the nominal voltage of the +/-10%)

Operating current: 5V: less than 80mA/per channel ( when relay not action is 1mA)

12V: less than 35mA/per channel (when relay not action is 1mA)

24V: less than 20mA/per channel (when relay not action is 1mA)
