Weidmuller’s two licensed frequency data modems that offer long-range communications—up to 40 miles—to extend Ethernet networks into difficult-to-access locations. Design features built into the new wireless Ethernet modems provide dynamic network optimization and intelligent routing for high reliability, lower latency, and deterministic power management. They support 360 to 512 MHz and 928 to 960 MHz configurations. They can operate in access point/client configuration, function as a network bridge/router, or serve as a Serial Server.

The modems also feature node-to-node deterministic mesh network repeatability for extended range, and multiple channel spacing options to increase network scalability. These licensed modems are optimized for throughputs of up to 25.2 kbps, providing secure wireless communications in challenging outdoor environments and over obstructed paths. The integrated Modbus server capability offers seamless integration with smart sensors, RTUs or I/O expansion through the use of expansion modules.

These modems integrate with Weidmuller wireless and wired networks to connect remote sensors, actuators and instrumentation to mission critical monitoring and control systems for industries that include oil and gas, water and wastewater, mining and power generation. The modems operate in an extended temperature range of -30 C to 60 C provide secure industry standard encryption of 128bit AES, 802.11i with CCMP, WEP, WPA2, and include ATEX/IECEx hazardous area approval. DIN-rail or wall-mount options are available for easy installation.
