Dettagli

4 canali 5V High Level Relè Shield With LED

product description:
1, the module in line with international safety standards, the control area and load the region has isolation trough;
2, the use of double-sided FR-4 circuit board design, high-end chip production process;
3, the use of loose music authentic relay control;
4, with power and relay action instructions, pull a bright, off does not shine;
5, the signal input terminal has a high signal, the common side and often open will be turned on;
6, the relay can directly control a variety of equipment and load;
7, there are four normally open and four normally closed contacts;
8, blue KF301 terminal connected to the control line is more convenient.
9, the module size: 72x41x18.5mm; Net weight: 56g
10, the finished product through the 100% functional testing and stability testing
Module Interface:
First, the input part:
VCC: Connect the positive pole of the power (according to relay voltage)
GND: Connect the negative pole of the power supply
IN1: 1-way relay module signal trigger side
IN2: 2-way relay module signal trigger side
IN3: 3-way relay module signal trigger side
IN4: 4-way relay module signal trigger side
Second, the output part (relay output):
1, normally open 1-4: normally open relay interface, the relay before the suction of the floating, after the short-circuit with the public
2, common 1-4: relay common interface
3, Normally closed terminal 1-4: Normally closed relay interface, the relay before the suction with the public short-circuit,
Trigger requirements:
If the signal is connected to other modules, it is necessary to connect the ground (power supply negative) between the two modules. If the power supply is shared, a single signal line can be connected.
High and low meaning:
High-level trigger refers to the signal trigger side (IN) and the negative power supply has a positive voltage between the positive and the power supply is usually connected to the trigger side of a trigger, when the trigger side voltage or trigger to reach the trigger Voltage, the relay is pull.
Low-level trigger refers to the voltage between the signal trigger terminal and the negative terminal of the power supply is OV, or the voltage of the trigger terminal is lower than the voltage of the positive pole of the power supply. When the voltage is low enough to trigger, the relay is pulled in, The negative side of the power supply is connected to the trigger side of a trigger, so that the relay is pull.
