Integrated Radio and I/O Design
The OleumTech® WIO® Radio Kit with Onboard I/O 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. The RM4 Kit is comprised of Radio Modules A and B.
The RM4 Wireless I/O Kit provides two unidirectional analog 4-20 mA inputs and outputs (Module A to B only). It also provides two independently configurable discrete I/O channels that can be set up for the signals to travel in either direction (Module A to B or B to A). For the sake of simplicity and ease of use, the I/O count in this system is fixed (non-expandable). The RM4 Kit is designed for use in non-hazardous/ordinary locations.
The original modular WIO System is also available if you require a scalable or customizable I/O solution.
Reliable, Robust, and Secure
The WIO System leverages reliable, robust, and secure RF technology that replaces traditional hardwire systems by eliminating the need to trench and run conduit and wire. Thus, the WIO System provides a significant reduction in both setup time and cost to its users.
The RM4 Wireless I/O Kit is available in 900 MHz, 915 MHz, or 2.4 GHz option. The Radio Kit comes paired from the factory, meaning there is no programming involved, and the over-the-air connection is instant once the system is up and running. The system offers secure RF communication using AES encryption and fail-safe output protection in case RF traffic is interrupted for any reason. The communication response time can be set to either 400 ms or 1 second, giving you additional control over update speed and power consumption.
