News: New 4DI-4DO-4AI Digital Analog AM2301/SHT20/SHT30/DS18B20 Temperature Humidity OPEN PLC Expansion Board for Arduino UNO R3 DNUNB17

DNUNB17 is an improved version of DNUNA16. It adds temperature and humidity acquisition ports based on the original version, and uses multiplexing of NPN input ports, resulting in 6 more free ports.









Product Features:





1 Working voltage: DC 7-30V(Recommend 9V/12V/24V)



2 Working Current : Standby curren 15MA, 1 relay open 41MA... 4 relays open 122MA



3 Rich external expansion resources: 4ch NPN Digital Input;4ch Dryt contact digital output; 4ch current and voltage analog input; 1CH temperature and humidity sensor input;RS485 Interface, 1 LEDs.



4 size 132*100*19mm(Only Board),136*115*29mm(with Din Rail Box)

5 Weight : 102g(Only Board), 225g(with Din Rail Box)





This is an expansion board for UNO R3, and the code(sketch) we provide is only used to test the experimental hardware.

If you need more functionality, write your own code. We do not provide additional code(sketch) and technical support







As long as you write ARDUINO code(sketch),You can use it to achieve a variety of delay timer function,such as:

AM2301/SHT20/SHT30 Temperature Humidity Collection

DS18B20 temperature acquisition (A4 pull-up 4.7K resistor)

RS485 Master-Slave Device(PLC MCU),

Modbus Protocol Relay

0/4-20MA Current Collection,

0-5V/10V Voltage Collection,

Motor forward and reverse control,

Multifunctional time delay relay

Power sequencer

Solar cell controller

And so on.







Note:

1. This board is only an expansion board; you will need to plug in the UN0 R3 development board to use it.

2. The NPN input ports (IN1-IN4) reuse ports D7-D10. To use them, set the DIP switch to the ON position.

3. For DS18B20 temperature acquisition, connect a 4.7K pull-up resistor to port A4.
