01 / Field acquisition
RS-485 / Modbus
Collect readings from multiple configured meters and compatible field devices.
Industrial Controllers
DIN-RAILIndustrialCONTROLLERS
ESUMEI industrial controllers mount on DIN rail and act as a gateway between RS485 field devices and IP networks. Use the G3 as an RS485 gateway for meters, sensors, and compatible industrial instruments—collecting data locally and forwarding it over cellular to a monitoring system. Built-in storage supports continuity when upstream connectivity is intermittent.
Remote cabinet operation
G3 field profile
