ET3420 4G Communication I/O Module

The ET3420 4G Communication I/O Module is an industrial wireless I/O and data acquisition device designed for remote monitoring, automation and industrial IoT applications. It combines 4G cellular connectivity, RS485 communication, four 4–20mA analog inputs and four 4–20mA analog outputs in a compact industrial module.

The ET3420 can collect analog signals from compatible field sensors and transmit the data through a 4G network for remote monitoring and analysis. Its analog outputs can also provide 4–20mA signals to compatible control equipment.

The module supports communication protocols including Modbus, MQTT, TCP, UDP and JSON, making it suitable for integration with industrial controllers, monitoring platforms, gateways and IoT systems.
