Product Description
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.

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.
