The WIO® System by OleumTech® is one of the easiest and fastest methods for eliminating wiring and enabling reliable, secure wireless connectivity to process variables, equipment or other assets within hours rather than days or weeks. The WIO System does not require any software or programming, making it one the of the easiest wireless I/O solutions available. The system replicates analog and discrete signals in both directions, enabling both monitoring and control capabilities. Secure AES encryption gives users a peace-of-mind system protection.


The WIO System can be monitored remotely in case there is either an RF or I/O failure with provided NPN discrete outputs on the Radios that can be tied to a third-party monitoring system. In the event of a failure, all outputs will automatically turned over to user’s predetermined FailSafe output states.


Although the WIO System does not require any programming, users still can take advantage of its Advanced UI designed for PC when commissioning and troubleshooting the system. By connecting a PC to the Radio Module’s mini-USB port, users can view and optimize RF strength, view input and output status, and locally force outputs for diagnostic testing. Users can also set the predetermined Fail-Safe values for analog outputs. Digital outputs are set using DIP switches that are physically located on the Digital I/O Module.


To build a WIO System, a Radio Kit is required. It includes two paired, point-to-point Radio Modules and all the mounting hardware for installing onto 35 mm DIN rails. Users simply add desired I/O Modules to the system in pairs. The supplied DataRails™ supports up to five pairs of I/O Modules to a system in any I/O combination. One system can support up to sixteen pairs of I/O Modules using optional longer length DataRails.
