Introduction
The GW IoT GXM 884 Gateway is a robust industrial device designed for remote monitoring, control, and data acquisition from multiple field equipments over 4G/LTE cellular networks. Acting as a Modbus RTU Master, it communicates with multiple Modbus slave devices at a single site and transmits structured JSON data to cloud or central monitoring servers using IoT protocols such as MQTT, HTTP, and FTP. In addition to serial communication, the gateway integrates 20 onboard I/Os—8 Digital Inputs, 8 Analog Inputs, and 4 Digital Outputs—enabling direct monitoring and remote operation of field signals and actuators. Designed for industrial panel installation, the gateway operates on a wide 18V–36V DC power supply, ensuring reliable performance in demanding industrial environments.
Designed specifically for deployment within industrial panels, the GW IoT G8M 884 provides a dependable communication link for sites where physical access is difficult or costly. By seamlessly integrating Modbus devices and local I/O signals with cloud-based IoT platforms, it empowers organizations to monitor asset performance, track process and environmental parameters, and perform remote control actions with greater efficiency, reliability, and operational control.
