Description:
1. The time can be adjusted by potentiometer to meet the needs of most of your occasions.
2. With Micro USB 5.0V power input, it is very convenient to use.
3. 5-30V wide range supply voltage.
4. External triggering and onboard buttons are two trigger modes.
5. With relay suction indicator.
6. The anti-interference ability is strong, and the relay will not misbehave under all kinds of disturbances, makes it suitable for industrial control.
Feature:
1. Working voltage: there are two kinds of power supply interfaces between wide voltage 5-30V, arbitrary voltage, MicroUSB and welding terminal.
2. Working mode:
A. After supplying power to the module, the output state of the module is: normally on (NO) and the common end (COM) disconnected, normally closed (NC) and the common end (COM) conduction.
B. The relay sucks and operates when a low pulse signal is given to the TRIG or when the trigger button is touched, and the indicator light is on. At this time, the state of the output of the relay is normally on (NO) and the common terminal.
C. (COM) on, normally closed (NC) and the public end (COM) off, after 0-24 seconds (this time can be adjusted according to your needs) after the clock relay off, at this time the relay back to the state before triggering.
3. Time can be adjusted by potentiometer, with a default of 0-24 seconds. If it takes longer, you can replace the larger capacitor (C2) or potentiometer. Delay time formula: T = 1.1RC. For example, capacitance 22uF resistance 1M. T=1.1*0.000022*1000000=24.2 seconds.
4. With relay suction indicator.
5. Module can be controlled: 10A 250VAC (AC), 10A 30VDC (DC) below load.
6. With Relay follow current protection.
7. The module signal terminal is designed with a pull up and filter circuit, which has strong anti-interference ability and is suitable for industrial control. The relay will not malfunction whether in the electromagnetic interference environment or in the instant when the module is on or off.
Application:
1. Anti theft alarm delay, building sound and light control switch.
2. The delayed connection of the on-board equipment prevents the electric current from burning when the car fires, and burns the vehicle equipment.
3. It is necessary to have sequential startup to prevent multiple devices from starting at the same time and over burning the appliance.
By adjusting the potentiometer can set the length of time
Micro USB 5.0V power supply with an input port, easy to use
5 ~ 30V wide supply voltage
External signal trigger and key trigger in two ways
With a relay indicator
Anti-interference ability, the relay at various interference will not miss operation, suitable for industrial control
1. Working voltage: wide voltage 5 ~ 30V, two power supply interfaces
2. Operating mode: the initial state, module outputs: normally open (NO) and the common terminal (COM) is disconnected, normally closed (NC) and the common terminal (COM) connected
Providing a low pulse signal, or touch trigger key, relay and indicator lights, the output of the state: normally open (NO) and Common (COM) connected, normally closed (NC) and the common terminal (COM) is disconnected. After 0-24 seconds (this time can be adjusted according to your needs) relay off, back to the state before the trigger
3. The length of timing adjustment by potentiometer, default 0-24 seconds. If you need more time, you can replace the larger capacitor (C2) or potentiometer. Delay time T = 1.1RC. For example: 22uf capacitor and resistor 1M, then T = 1.1 * 0.000022 * 1000000 = 24.2 seconds
4. With a relay indicator
5. The module can control: 10A / 250VAC, 10A / 30VDC load
6. The relay has a freewheeling protection
7. Trigger signal input terminal is designed with a pull and filter circuit, enhanced anti-jamming capability, suitable for industrial control. Many manufacturers add the optocoupler isolation, but there is no separation between module’s ground and signal’s ground, would not achieve the interference effect. After the test found that only enhance the stability of the signal input port to interference, regardless of this module is under electromagnetic interference environment, or in the power-up and power-down moment, the relay will not produce miss operation
8. Dimensions: 5.5 * 2 * 1.8cm / 2.16 * 0.78 * 0.7″
9. Burglar, alarm, building delay switch, sound and light control light switch
10. Delay powered vehicle equipment, to prevent large currents generated as the car starts burning vehicle equipment
11. Prevent simultaneous launch multiple devices cause burning appliances or fail to start
