4G/GSM PLC

xLogic 4G/GSM PLCs bring remote monitoring to sites with no wired network — pump stations, greenhouses, remote equipment. Modbus, MQTT and BACnet run over the built-in Ethernet port, while the 4G/GSM module carries the connection to the cloud, so you can check alarms and parameters from anywhere.

Application Cases

Real machines, real control problems, solved with xLogic micro PLCs and smart relays. Each case walks through the application, the hardware selection and the control logic behind it — from packaging lines and pump stations to temperature control. If you build or retrofit similar equipment, the model recommendations inside each case show exactly which xLogic CPU fits.

RIEVTECH PLCs are high-performance industrial automation devices built for reliable control of HVAC, machinery and general industrial applications. Equipped with flexible digital and analogue I/O interfaces and supporting Modbus communication, these PLC systems deliver stable real-time control with rich expansion capabilities. Compatible with Nano, Micro, Ethernet, WiFi and 4G models, they support FBD/Ladder programming and easy integration with HMI and SCADA systems. Ideal for building automation, food processing equipment and small-to-medium machinery projects, our controllers greatly reduce engineering workload and hardware costs compared with traditional control solutions.
