4~20mA Wireless IoT Module
The 4~20mA Wireless IoT Module is a wireless Internet of things gateway, designed for converting 4~20mA analog transducer signal to Wireless communcation over SMS/GPRS/3G/4G/NB-IoT Cellular Network, and connect to the IoT Cloud Platform.
The 4~20mA Wireless IoT Module suitable for pressure transducers, wind speed transducers, oil level transducers,liquid level transducers,etc.
The 4~20mA Wireless IoT Module supports Modbus TCP Protocol and MQTT Protocol, compatiable KPIIOT cloud platform and other cloud platform or SCADA or OPC Server.
1. Can be used as a complete product or as a secondary development module;
2. Two working modes are available:
Normal mode: Real-time data transmission,Users can inquiry the real-time status;
Low power consumption mode: Ultra low power consumption(＜230uA);
3. Multiple communication methods:GSM,GPRS,3G,4G,NB-IoT,LoRa,Ethernet,etc;
4. Coverting 4~20mA analog signal to cloud platform over cellular network;
5. Support configure parameters and query real-time data via SMS,software,cloud platform;
6. Up to 10 SMS Alert and dial numbers, can program to receive specified alarm message;
7. Support two different server centers,can set IP address or domain name ;
8. Support Modbus RTU over TCP and MQTT protocol;
9. Wide range power supply 7~24VDC with phase-reversal protection;
10. Using Nano sim card,support PIN code function;
11. Provide PCBA or waterproof enclosure,can be used outside.
