Red Relay Supports High And Low Level Triggerin

The Blue Relay Supports Low Level Triggering

Module description:
1. the module uses genuine quality relay,normally open interfaces Maximum load: AC 250V/10A,DC 30V/10A;
2. using SMD optocoupler isolation,driving ability,stable performance; trigger current 5mA;
3. the module Operating voltage 5V 12V 24V ;
4. the module can be high or low by a jumper setting trigger;
5. fault-tolerant design,even if the control line is broken,the relay will not operate;
6. the power indicator (green),the relay status indicator (red)
7. the interface design of human nature,all interfaces are available through a direct connection terminal leads,very convenient
8. module size: 50mm*26mm*18.5mm (L*W*H)

Module interface:
1. DC+: positive power supply (VCC)
2. DC-: negative power supply (GND)
3. IN: can be high or low level control relay

Relay outputs:
1. NO: normally open relay interface
2. COM: Common Interface Relays
3. NC: normally closed relay interface

Product description:

1,The module complies with international safety standards,control area load area isolation groove;

2,Genuine relay Songle;

3,With the power and relay action instructions,pull bright disconnect does not shine;

4,When a signal in the signal input terminal,the common terminal and the normally start conduction;

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

6,The control of the DC or AC signal,can control 220V AC load;

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

8,Blue KF301 terminals to the line of control is more convenient.

Description of the high and low trigger,friends do not understand Take a look at:

High level trigger is a trigger voltage between the signal input and ground can be understood as a way of the signal input terminal and VCC cathode short trigger;

Low trigger means is the voltage between the signal input terminal and the ground for the OV trigger mode can be understood as a way of the signal input terminal and GND negative short trigger
