【 A brief description 】
1. Size: 68mm *21mm
Second, the main chip: NE555
3. Working voltage: DC 12 volts
4. Features:
1. When the power is turned on, the relay will pull in with a delay time (this module only has the function of delay suction and no delay disconnection function, unless the power is off). Specifically: after power-on, the relay will not immediately pick up and the state of the relay output terminal is: normally open and common disconnection, normally closed and common conduction; after the delay time 1~105 (the delay time is adjustable), The relay is absorbing. At this time, the state of the relay output terminal is: normally open and public conduction, normally closed and public disconnection; as long as the module is not powered, this state (relay suction state) will always be maintained. Test phenomenon: After the power is turned on, the red power indicator lights up, and after a delay of 1~105, the relay picks up, you will hear a "click", and the blue relay pick-up indicator lights up.
2. The delay time is adjustable, (0 ~ 10 seconds)
3. Adding a potentiometer can increase the delay time
4. Increasing the capacitor lead can increase the delay time
5. With input power indicator
6. With relay pull-in indicator light
7. Can control AC 220V/10A equipment. (Control device 2000W)
8. With relay freewheeling protection.
9. Delay time formula: T = 1.1IRC. For example: Capacitor 100uf Resistor 100K T=1.1* 100000*0.0001=11 seconds
【 Applications 】
1. The on-board equipment is connected with a delay time to prevent the vehicle equipment from being burnt due to excessive current when the car is on fire.
2. When it is necessary to start sequentially, prevent multiple devices from starting at the same time and the current is too large to burn the electrical appliances.

Module features
 
Long-distance wireless transmission (up to 500 meters in open area , 10kbps baud rate in the air )
 
Operating frequency range ( 433 - 458.5MHz , up to 255 communication channels)
Maximum 100mW ( 20dBm ) transmit power ( 10 levels of power can be set )
Built-in MCU, use serial port to communicate with external devices
 
Send 31 bytes at a time
 
The module can support one-to-one, one-to-many transparent transmission communication through ID setting Changing the baud rate of a different serial port will synchronously change the rate at which data is sent over the air. ( 10kbps-100kbps)
 
Set the ''critical three minutes''. The module can send and receive data normally within three minutes of power-on. You can send the AT command '' AT ENABLE=1 '' to make the module enter the AT command state for parameter setting. There is only this reserved word in these three minutes. After more than three minutes, you will not be able to enter the AT command mode, you can only send and receive data, '' AT ENABLE=1'' will also be sent out as data, there are no reserved words at this time.
 
 
 
 
 
 
For more information, please contact me
Recommend to buy more than 2pcs!!!
How to use (>=2pcs):
1 2PCS,Module 1 and Module 2 send data to each other.
 
2 >=3PCS,One as master device, the other as will be as slave device.
the way they work as well as wired RS485 bus. Master device transmit data, Slave devices all receive data.Any slave device transmit data, master device and the other slave devices can receive .When ever only allowed one device (master or slave) to transmit data.

Features(If you need a chip brochure please contact me) :
 
The DD30CRTA is a PWM switch-mode battery charger controller for 12V lead-acid battery in a small package using few external components.
The DD30CRTA is specially designed for charging 12V lead-acid battery with trickle charge, constant current charge, over-charge and float charge mode.
In over-charge and float charge mode, the regulation voltage is internally set. 
The constant charge current is programmable with a single sense resistor.
 
Deeply discharged batteries are automatically trickle charged at 17.5% of the programmed
constant charge current until the cell voltage exceeds 75% of the regulation voltage in
over-charge mode. The over-charge is terminated once the charging current drops to 38% of the
constant charge current, then DD30CRTA will enter float charge mode. A new charge cycle
automatically restarts if the battery voltage falls below 83.95% of the over-charge voltage in
float-charge mode. DD30CRTA will automatically enter sleep mode when input voltage is lower than battery voltage.
Other features include undervoltage lockout and status indication, etc.
 
 
The Regulation Voltage in Over Voltage Mode and Float Charge Mode 
The regulation voltage VOC at BAT pin in over charge mode is set at 14.8V(Typical) with ±1.5% accuracy.
In float charge mode, the regulation voltage VFLOAT at BAT pin is 91.57% of that in over charge mode, which is 13.55V(Typical).
Trickle Charge Mode At the beginning of a charge cycle, if the battery voltage is below 75% ×VOC, the charger goes into trickle
charge mode with the charge current set at about 17.5% of the constant current.
 
End-of-Over Charge Current
When the battery voltage approaches the over-charge voltage, the charger goes into the over charge mode. In
over charge mode, the charge current start to decrease and when the charge current drops to 38% of constant
charge current, the charger goes into float-charge mode.
 
Float Charge Mode
After the over voltage charge is terminated, the charger goes into float charge mode. In float charge mode, the
battery voltage is regulated to 91.57% ×VOC, namely 13.55V(Typical). Float charge mode can compensate for
the loss of battery power due to self-discharge or external loading.
 
Automatic Battery Recharge
In float mode, if both the battery and the input power supply (wall adapter) are present, a new charge cycle will
begin if the battery voltage drops below 83.95% ×VOC due to self-discharge or external loading.
A new charge cycle can also be started manually by plugging off the input supply and reapplying it.

NC          : Relay normally closed contact
Open       : NO connection COM, NC disconnect COM
Close      : NO disconnect COM, NC connection COM
Momentary  : Press the Transmitter button , the receiver relay is Open, release button;the relay  is Close;
Toggle        : Press transmitter button for 1 time , the receiver relay is Open, press button again, the relay  is Close;
Latched       : Press transmitter button A, the receiver relay is Open  Press transmitter button B, the receiver relay is Close.
Delay           : Press the Transmitter button, the receiver relay Open,After a set time delay, the receiver relay  is Close;
 
If during the delay, press the button of Transmitter, delay start again; if the delay period, press and hold  the button of Transmitter 3-4 seconds, the receiver controller stops the delay, the relay Close
 
Adapter remote control (learning remote control):
Under normal operating mode, LED will be lit, when receives a valid remote control (EV1527 / PT2262) button values, LED flashes
 
Clean code: press the key and held down, LED off, LED will light about 8 seconds later, clean code is completed (Note: After performing clean code previously stored remote control value does not exist)
 
Step 1 (into the learning mode): Press the key (about 1 second), LED off;
Step 2 (adapter button): Then press the utton on the remote control, LED flashes four times on, then learning the button value
 
Note: 
Only the Non-locking (Momentary is defult),Self-locking (Toggle),Inter-locking (Latch) mode to a "clear code" and " learning " action
 In the "delay" mode can only set the delay time
 
 
Delay setting:
Step 1, the mode is set to "delay" mode (jumper cap on the M1 into two rows of pins)
Step 2, press the key until the LED is off
Step 3. Click the key again, LED flashes
Step 4. Click the key again after a period of time, LED light
LED blinking time is the delay time.

Attention :
    
This is a DC-DC voltage converter module,Must be noted when using:
1 Input voltage can not be greater than the maximum input range
2 Output power can not be greater than the maximum load for a long time
3 Input power must be greater than the output power, because the power consumption of the module itself
 
Q & A:
  
Q1 : Why output voltage is less than the nominal voltage
A1: Input power supply power is too low.Test the input voltage with a multimeter,a t this time of the input voltage is very low
 
Q2 : Why is the negative voltage not output or the output too low?
A2 : The negative voltage cannot be used alone. When using a negative voltage, the same load must be connected at the positive voltage terminal.
