Wireless I/O Extender
Extend digital and analog signals up to 40km on a wireless link
KTA-296 is sold as a pair.
The KTA-296 Wireless I/O extender pair offers a convenient way for analog or digital signals to span large distances via a wireless link. It is designed to operate as a pair, where the I/O from one unit "mirrors" the I/O from the other. That is, the digital inputs on one unit trigger the relay outputs on the other unit, and the analog inputs on one unit sets the analog outputs on the other.
The radios are rated to 40km range (line-of-sight), using the stock antennas, or further with the Yagi antenna (sold separately: RFD-010). A single antenna can be used, but two is recommended for best performance; diversity switching is employed, meaning that the antenna with best reception is automatically chosen. Communication is done in the 900MHz ISM band, which is free to use without a license. Full spread spectrum techniques are used to minimise the effects of interference and multi-path reflections that may otherwise degrade the radio link, particularly in industrial environments.
