Go anywhere using the power you already have


groov RIO brings IIoT connectivity to edge I/O

Before you can read even one field I/O data point, you have to meet precise technical requirements and environmental conditions. groov RIO simplifies both with industrial-grade hardware and flexible installation options that let you get to work faster. Then, groov RIO's data processing and storage at the edge give you reliable data you can use where it's needed.

Industrial-grade hardware

The way industrial devices interact with their environment can affect the safety of equipment, processes, and personnel. The more vulnerable a device is, the more work it takes to design and install appropriate protections or isolate it from exposure. To ensure you can capture important I/O data right at the source, groov RIO is designed for harsh environments, with:

  • UL Hazardous Locations approvals (Class 1/Division 2)
  • ATEX compliance
  • Wide -20 to 70 °C operating temperature range
  • Compact 1.9” x 5.2” form factor (download CAD file

Since all Opto 22 products are tested through their full range of operation, you know these are specs you can rely on.

Flexible installation options

Thanks to this industrial-grade hardware, you can place groov RIO just about anywhere.

Ready for either DIN-rail or panel mounting, this hardy edge I/O module can go right next to sensors, machines, equipment, legacy PLCs, or systems that have the data you need.

Power options give you even more flexibility. With Power over Ethernet (PoE) built into one of its Gigabit Ethernet interfaces, you can use 802.3af PoE Class 0 connections to supply power to both groov RIO and field I/O. Or you can connect a 10-32 VDC power supply to the RIO's power terminals. 

If your application needs an additional device, like a Wi-Fi adapter, a USB memory stick, or a USB-to-serial adapter, you can supply it and connect it to the USB host port.

Processing and storage

Edge I/O takes the concept of edge computing—distributed processing power in the field—and applies it to the difficult job of collecting, processing, and publishing remote I/O data. groov RIO provides:

  • An industrial ARM® processor, 1 GB RAM, and 4 GB user space (or 2 GB RAM and 7 GB user space with GRV-R7-MM2001-10) on industrial eMMC with a power-fail-safe filesystem
  • Expandable local data and file storage via USB host port
  • Advanced data formatting, sanitization, and aggregation through the embedded Node-RED software, designed for IIoT applications
  • Efficient data transfer using MQTT communications 

And there's more...

With groov RIO universal edge I/O models, there's no need to specify an exact interface; design a custom electrical panel for signal, power, and network distribution; or install additional connectivity hardware. The guess-work, time, and cost are minimized with 8 configurable channels for analog or discrete inputs or outputs, plus 2 electromechanical relays. One part number gives you thousands of possible field I/O combinations. And with the RIO MM2, you can even run Ignition or Ignition Edge right on the module.

With the groov RIO energy monitoring I/O model, you can monitor three-phase, twin-, or single-phase loads up to 600 V, with either Delta or Wye wiring. For current measurement, you can use 0.333 VAC, 1 VAC, or 5 A Category III current transformers (CTs) and, if necessary, use a different CT type on each circuit.
