Pushing the limits of 450MHz radio technology to the edge and beyond, the E-Series of data radios offers all the performance, power and flexibility needed to meet the communications requirements of today's complex SCADA systems.

The E-Series is comprised of dedicated half and full-duplex (ER450) remote radio variants, a base station model (EB450) and a hot stand-by base station controller (EH450) that provides true redundant base station radio operation.

The products are fully user-configurable for transmitter power, frequency tuning (~13 MHz sub bands) and data port performance parameters, are equipped with a dedicated system port and have dual serial user ports and integrated multiplexer that can facilitate remote RTU configuration.

Like their cousins the J & K Series, E-Series radios take advantage of innovative features such as support for multiple data streams, collision-avoidance algorithms and network management and remote diagnostics.

E-Series products are engineered for extreme installations with robust metal-alloy remote radio housings, high duty-cycle base stations and an operating temperature range of  -30 to +60ºC (-22 to 140ºF).
