Core Advantages
4G/3G/2G & Dual SIM/eSIM
Supports extensive 2G/3G/4G cellular network access, with 4G LTE options including Cat1/Cat4/Cat6. Equipped with dual SIM and dual eSIM capabilities to enable flexible switching and link backup.
100Mbps Ethernet Interface + Wi-Fi
Equipped with a 100Mbps Ethernet port supporting WAN/LAN auto-sensing and Wi-Fi 4 (2.4 GHz) wireless access, it combines stable wired transmission with convenient wireless connectivity, meeting the needs for industrial equipment networking, data transmission, and on-site network deployment.
Single Serial Port Interface
Integrates one serial port supporting either RS232 or RS485 (selectable), facilitating connection to various industrial devices for reliable data communication.
TesproOS System & Remote O&M
Equipped with the proprietary TesproOS operating system and a visual web-based management dashboard, it enables full-lifecycle device management. It supports real-time cluster status monitoring, remote batch parameter configuration, log diagnostics, and cloud-based OTA firmware upgrades; combined with multi-layer VPN encryption, it facilitates efficient O&M without the need for on-site visits.
Rich Protocol Ecosystem
Integrates northbound cloud protocols (MQTT/OPC UA), industrial fieldbuses (Modbus/ProfiNet), and power/energy protocols (DLT645/IEC61850). Combined with OpenVPN/IPSec encryption and rapid custom protocol development, it simplifies device onboarding for plug-and-play deployment and accelerates OT-IT data convergence.
Excellent Weather Resistance
Supporting a wide operating temperature range of -40°C to +75°C and non-condensing humidity levels of 5% to 95% RH, alongside an IP30 protection rating, it reliably handles complex and harsh industrial environments—including high altitudes, high temperatures, and high pressures—to ensure stable equipment operation.

-
How does the TG-100 separate local equipment from the upstream network?
-
The TG-100 provides one WAN port and one LAN port. The LAN port can connect local PLCs, HMIs, or other field devices, while the WAN port or cellular connection handles communication with cloud platforms or remote servers, helping separate field-side and uplink traffic.
-
Does the TG-100 support different data collection schedules?
-
Yes. The TG-100 supports real-time collection and reporting, interval-based collection, timed reporting, and customized collection methods. This allows the data acquisition strategy to be adjusted according to different applications.
-
Can the TG-100 convert field data and upload it directly to a cloud platform?
-
Yes. The TG-100 supports protocols such as Modbus, BACnet/IP, and BACnet/MSTP, together with TCP Client, UDP Client, MQTT Client, and transparent transmission modes. It can collect and process field data before forwarding it to cloud platforms or backend systems.
