Introducing groov RIO: I/O for the IIoT

Intelligent, multi-signal, multifunction, PoE-powered, remote Ethernet I/O for IIoT and automation applications

groov RIONow with one compact unit, you can:
  • Power the unit and connected I/O with 802.3af PoE Class 0 switches, or a 10-32 VDC power supply
  • Wire up to 8 channels of mixed I/O signals (configurable for temperature, current, voltage, or discrete inputs or outputs), plus 2 mechanical relays.
  • Run optional distributed features independently on the processor, including counting, thermocouple linearization, digital totalizing, minimum/maximum values, ramping, and more
  • Integrate I/O data directly with databases, HMIs, SCADA systems, cloud services, and IoT platforms, using embedded Node-RED
  • Connect to existing control systems or building automation systems with Modbus/TCP, OptoMMP, and REST APIs
  • Publish process data directly into publish-subscribe architectures with MQTT and Sparkplug or string payloads
  • Log data to internal power-fail safe memory or an attached USB mass storage device
  • Protect with built-in security, including configurable firewalls, encryption, user accounts, and VPN client
  • Install anywhere with wide -20 to 70 °C rating, UL Hazardous Locations approval, ATEX compliance

If you have a small, mixed I/O count application, especially requiring I/O data logging or data communications, count on groov RIO.


I/O signal options are (almost) endless. You can configure 61,260 unique field I/O combinations with one groov RIO unit! How is this possible? We've documented how we got these results here:
