Simple PLC Development Module Digital Analog Temperature Humidity RS485 Relay Expansion Board for Arduino UNO R3(with Din Rail Box)

DNUNB17 is a multifunctional expansion board for Arduino UNO developed and produced by eletechsup. Based on it, you can develop analog input IO ports, 4-20MA/0-10V acquisition, AM2301/SHT20/SHT30/DS18B20 temperature and humidity acquisition.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 122MA3 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 supportAs 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 CollectionDS18B20 temperature acquisition (A4 pull-up 4.7K resistor)RS485 Master-Slave Device(PLC MCU),Modbus Protocol Relay0/4-20MA Current Collection,0-5V/10V Voltage Collection,Motor forward and reverse control,Multifunctional time delay relayPower sequencerSolar cell controllerAnd 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.Rich Onboard Resources2CH 4-20MA Current Input2CH 0-5V/10V Voltage Input4CH NPN Digital Input4CH Relay Output1CH Single bus sensor(e.g. AM2301)1CH Dual bus sensor(e.g. SHT20/SHT30)1CH LED Output1CH RS485 BUS6CH Remaining portsProduct model: UM100Color: GreenWidth: suitable for PCB board width UM100(100mm)Insulation grade: flame-retardant VO gradeBackplane length: suitable for 132 mm PCB boardsNet weight: 122gInstallation: DIN35 and C45 rail
