Specification:
Brand new and high quality.
product description:
1, the module control area and the load area has isolation slot;
2, the use of double-sided FR-4 circuit board design, high-end chip production process;
3, using Songle relay control;
4, with power and relay action instructions, pull bright, off does not shine;
5, the signal input low-level signal, the common terminal and normally open will be turned on;
6, the relay can directly control a variety of devices and loads;
7, there is a normally open and a normally closed contact;
8, blue KF301 terminal access control line more convenient.
9, the module size: 43x17x18.5mm;
Module Interface:
Input section:
VCC: connect 5V power positive (according to the relay voltage)
GND: Connect to the negative terminal of 5V power supply
IN: relay module signal trigger terminal (active low trigger)
High and low meaning:
High-level trigger refers to the VCC side of the positive voltage with the trigger-side connection of a trigger, when the trigger side has a positive voltage or trigger voltage, the relay is closed.
Low-level triggering refers to the triggering mode of connecting the negative voltage on the GND terminal to the trigger terminal. When the trigger terminal has a voltage of 0V or the voltage is low enough to trigger, the relay is turned on.
Electrical parameters:
Voltage version, quiescent current, operating current, trigger voltage, trigger current
12V, 5.5mA, 42mA, 0-4V, 3mA
