Y212-GWR is a field gateway for sites that cannot rely on one network path. It combines RS232, RS485, 4G LTE, 2.4 GHz Wi-Fi and dual RJ45 Ethernet in one DIN-rail-ready device, so PLCs, meters, pumps and monitoring stations can stay reachable through WAN, Wi-Fi or 4G backup.
Best Fit
- Remote cabinets that need serial data plus network backup.
- Pump stations, energy cabinets, environmental stations and municipal equipment.
- Projects where local Ethernet, site Wi-Fi and cellular fallback may all be used.
What Makes It Different
- Automatic uplink priority: WAN > Wi-Fi > 4G.
- RS232 + RS485 for mixed legacy device access.
- Wi-Fi AP mode for local commissioning, STA mode for joining an existing WLAN.
- Remote configuration, OTA, alarm reporting and log access.
- Industrial power input and watchdog protection for unattended sites.

Before Ordering
Please check local cellular bands before using this model outside China and Southeast Asia. It is not recommended for the United States or Canada because key local LTE bands are not sufficiently covered by the current Cat.4 version.
