FreeWave Technologies, manufacturer of high-performance spread spectrum and licensed radios for critical data transmission, has introduced three additional models with several new and improved features to its IO Expansion family.

Officials with FreeWave said that the new additions make it easier for customers to leverage their existing hardware investments with significant performance improvements.

According to company officials, the FreeWave IO Expansion family is especially well-suited for applications in the water purification, wastewater treatment, oil and gas automation, agriculture irrigation, monitoring and control markets.

"We created our IO Expansion series to meet the needs of customers who want more IO, but don't want to have to purchase a new system to get the additional IO points," said Ken Granader, vice president of sales at FreeWave, in a statement.

Granader said that based on customer feedback, the company continued developing new models with enhancements that make IO Expansion available for a wider range of applications and compatible with more radios.

Company officials said that the IO Expansion Module is known for offering a scalable IO solution with up to 12 IO points per module. Also, up to 16 modules can be stacked on the radio or base module - allowing up to 192 additional IO points per 16 module stack.

This, company officials said, adds significant flexibility to an existing FreeWave Modbus IO network.

Now, with the introduction of the Serial Base, expandable IO points can be added to any existing serial network regardless of manufacturer. Along with the peace of mind that goes with 100 percent temperature tested radios, users can rest assured of measurement accuracy, company officials said.

The 0.10 percent accuracy of analog input measurements across the entire operating temperature means that users can be confident in the reported measurements and reduce their process errors.
