Engineered for universal building-to-industrial integration with seamless Modbus connectivity.
Downlink Modbus RTU Master and Modbus TCP Master — uplink Modbus RTU and Modbus TCP. One gateway for all Modbus devices.
Replace multiple proprietary gateways with a single universal gateway — reduce hardware costs, cabling complexity, and maintenance overhead.
4G, WiFi, or Ethernet with wired priority and automatic 4G failover — always online. Optional GPS for asset tracking.
9–36V DC wide input, reverse‑polarity protection, -40~85°C operation, EMC Level 3 (ESD/EFT/Surge), 2KV isolation.
DIN35 rail or wall mounting with patented rail‑clip — quick installation in electrical panels, chiller plants, and equipment rooms.
Supports Modbus RTU to Modbus TCP, Modbus TCP to Modbus RTU, and transparent transmission.
