The Edge Controller That Does It All No Cabinet Rewiring Required.

Power. Control. At the Edge.

Universal remote I/O with Edge-ready intelligence

The groov RIO M1 and M2 modules offer software-configurable, multi-signal I/O in a compact, industrial form—eliminating the need for custom wiring and multiple I/O cards. With built-in edge processing, dual Ethernet ports, and native protocol support, groov RIO is designed to deploy fast, scale easily, and integrate seamlessly into both traditional and IIoT systems.

Choose the M1 for standalone I/O and edge data publishing, or step up to the M2 for full control with PAC Control Runtime and certified Ignition Edge support. Both devices come ready with built-in Node-RED, Python, and REST APIs for edge automation and data handling.

groov RIO’s software-defined I/O allows one device to handle multiple signal types — from digital and analog to thermocouples and RTDs. Integrators save on design and wiring time, OEMs standardise builds, and engineers gain local data control and cloud connectivity in one drop-in unit.

With universal I/O, secure networking, and open protocols, groov RIO M1 and M2 remove traditional automation barriers. Get real-time control and communication with zero additional software licences, central processors, or proprietary lock-ins.
