FreeWave Technologies has announced a new suite of IO Expansion products to help customers achieve optimal performance, faster ROI and customization for communication networks. FreeWave's IO Expansion modules increase the degree of monitoring, control and optimization, and offer the most flexible and easily expandable wired and wireless IO available in the market today.

FreeWave features expandable IO devices that offer universally configurable IO channels for analog input, analog output, digital input, digital output and sensor power.

The new IO Expansion modules provide faster access times for up to 192 IO points. They also offer internal user selectable pull up and pull down resistors for all non-isolated inputs to ease product installation and reduce the number of external components. Additionally, the IO Expansion products carry the same measurement accuracy of analog inputs, and can snap directly onto FreeWave radios or connect to any other serial communication device, thereby leveraging customers' existing hardware investments.

In electric power, a higher concentration of IO points in a single connection simplifies transformer monitoring and eases environmental and condition monitoring of coal ash ponds.

New models and additional enhancements to FreeWave's IO Expansion family include:

• IOE-4440 Serial Base and IOEX-4440 Expansion Module - Four universal channels, four input-only channels, four isolated digital input channels and no isolated digital output channels
• IOE-4422 Serial Base and IOEX-4422 Expansion Module - Four universal channels, four input-only channels, two isolated digital input channels and two isolated digital output channels
• IOE-4404 Serial Base and IOEX-4404 Expansion Module - Four universal channels, four input-only channels, no isolated digital input channels and four isolated digital output channels
