Custom-Tailor I/O Mix, Bi-Directional

The OleumTech® WIO® Modular Wireless I/O System provides instant I/O connectivity and is one of the easiest and most cost-effective solutions for solving a vast number of point-to-point I/O and stranded asset monitoring and control challenges. Each Radio Kit can be fully
customized using available 0-10 Vdc, 4-20 mA, and Digital I/O Modules. The bi-directional connectivity gives you the flexibility to connect third-party equipment such as PLC or RTU to either side of the radio link.

Just Add I/O Modules

Constructing a WIO System begins with a WIO Radio Kit. The kit includes a factory-paired Radio set and all the mounting hardware necessary for installation onto 35 mm DIN rails. Then, simply add matching pairs of I/O Modules to get just the right mix of I/O. There are three available I/O Modules to choose from: Analog 4-20 mA, Analog 0-10 Vdc, and Digital. Each paired Radio System provides a secure I/O link using AES encryption. You can safely and reliably run multiple radio pairs in close proximity.

No Programming Required

Not having to learn or program any software is what makes the WIO System so easy to use. And although this system does not require any programming, an Advanced UI (User Interface) for PCs is available to take full advantage of the entire feature set. Through the Advanced UI, you can view and optimize RF strength; view input and output status; set analog fail-safe output values; locally force outputs for diagnostic testing; and more.

Fail-Safe Output Protection

You can set the predetermined value for each output in case of a RF or I/O failure. DIP switches are used for the Digital I/O Module to control the fail-safe output settings. The Analog I/O Modules default to 0 V or 4 mA. Advanced UI can be utilized for setting any other desired value. The system’s RF and I/O health can be remotely monitored by tying the NPN outputs on the Radio Modules to a third-party monitoring system.
