The I/O Expansion module offers a reliable, safe and easy way to meet the growing
measurement and control demands of your automation system. I/O Expansion
builds on existing communications systems and controller infrastructure to extend
the useful life of your automation system. The Expansion Modules snap easily on
to a radio base to provide 188 I/O points over a single wireless link. The Serial Base
features a wired serial interface to provide up to 192 I/O points to an existing PLC,
RTU or other device with serial communications.
All radios are designed, manufactured and tested in Boulder, CO.
