245U-E

Operating at 2.4GHz or 5GHz and up to 400mW, the ELPRO 245U-E is optimized for throughputs of up to 108Mbps which provides robust and secure two-way wireless communications in challenging indoor and outdoor environments typical of industrial monitoring and control applications.

Capable of operating in Access Point/Client configuration, functioning as a network Bridge/Router, or serving as a Serial Server (RS232/485), the ELPRO 245U-E offers node to node deterministic mesh network repeatability for further range and multiple channel spacing options to increase network scalability.

Integrated Modbus server capability allows seamless I/O expansion through the use of ELPRO 115S Expansion modules.
