CGate-05
The CGate series are dedicated IoT gateways purpose-built for Modbus devices. With complete device-management services built in, you can monitor every field point in real time through the web interface and sync to the cloud or your back-end.
mini-PCIe 4G LTE Module
Installs in the internal slot; SIM card not included
microSD Storage Expansion
Expands log storage; requires opening the case
Product Highlights
Low-Power Compute Core
NanoPi NEO Core (Allwinner H3 1.2GHz) — low power draw, stable in continuous operation.
Proactive Alarming
An abnormal reading on a monitored point triggers a proactive report — writing a log entry, sending email, and driving a DO output.
4G Module
An optional 4G module gives you an uplink where no fixed-line network is available.
Local Storage & Cloud Upload
Runtime data is stored locally for historical queries and published to the cloud over MQTT — two independent channels.
Modbus Agent
Define where polled data is stored in the Modbus map — one unified data source, served over Modbus-TCP.
Web Real-Time Monitoring
No extra software to install — open a browser to see field devices and every monitoring point.
Field Environment Suitability
Operating temperature −20 to 70 °C at 20–80 % RH — mountable in control cabinets in unconditioned plant rooms.
