Relay output contact with double - line, can withstand large current more secure

Product introduction:

1, this module is in line with international safety standards;

2, the use of pine music authentic relay;

3, with power supply and relay indicator, pull off bright, bright;

4, when the signal input signal, G1 public and K1 often start will lead;

5, can be used as a microcontroller development board module, can be used as a home appliance control;

6, control the DC or AC signals, can control the 220V AC load;

7, there is a normally open and a normally closed contact;

8, blue KF301 terminal connected to the control line is more convenient.

9, the relay net to theHFor the high level trigger selection, that is, short H

Blue block net to theHEnd to and INShort circuit

10,Net to the relayLLow level trigger selection, that is, short L

Blue block net to theLEnd to and IN short connection

11, VCC for the power cathode,IN is the trigger input,GNDNegative electrode for power supply.

On the high level and the low level of the trigger instructions, do not understand the friend please look at:

High level trigger refers to the signal input terminal and the ground between the trigger mode, can be understood as the signal input and VCC cathode short-circuit trigger a way;

Low level trigger refers to the signal input terminal and the voltage between the ground for the OV trigger mode, can be understood as a signal input terminal and GND negative short-circuit trigger a way
