1:Digital inputs 1-16 can connect some sensors like door sensor/PIR sensor/Gas sensor/Smoker sensor and the self-reset wall switch to control output 1-16.it can trigger the output or sens message to the phone

2:Analog input1-2 is 4-20mA,connect with sensor like Pressure sensor,3-4is 0-5V,connect with sensor like water level detection sensor

3:GPIO’s 1-3 is Temperature and humidity detect sensor port like DHT11/DS18B20,You can connect many pcs DS18B20 to one port,you can read each one on the computer or phone APP

4:RS485(MODBUS) can connect with Power meter

5:315MHz/433MHz RF sender and receiver port:we can use RF wireless signal to control A16 AS wireless switches

6:Ethernet communication:we can implement MQTT communication or LAN communication through Ethernet interface

7:Output connection 1-16:can be 12V or 24V

8:I2C Extension interface:can be connected to DO8 for relay expansion via I2C interface let 16channels become 24 channels
