groov RIO, 8 in/out multi-signal, 2 mech relay

Production Specification

groov RIO® revolutionizes remote I/O by offering a single, compact, PoE-powered industrial package with web-based configuration, commissioning, and flow logic software built in, plus support for multiple OT and IT protocols.

You can use groov RIO units in two ways.

  • As a standalone I/O unit (I/O for the IIoT), communicating data between field devices and data destinations. You can:
    • Push data directly to on-premises or cloud apps, databases, or other software, typically using the included Node-RED
    • Publish data to an MQTT broker
    • Respond to Modbus/TCP requests for data
  • As traditional remote I/O with a groov EPIC processor running PAC Control or a custom control program. Custom programs work through either RIO's OptoMMP memory map or its REST API.

The GRV-R7-MM1001-10 is a 10-channel, multi-signal, multifunction remote I/O unit. Its communications processor has two switched Gigabit Ethernet interfaces, one capable of Power over Ethernet (802.3af PoE Class 0) connections, supplying power to both groov RIO and field I/O. It also has:

  • Supply terminals to connect to a 10-32 V DC power supply.
  • A USB host port, which can be used to connect additional devices like a Wi-Fi adapter, a USB memory stick, or a USB-to-serial adapter (none included).
  • Status LEDs to display the status of power, network, and I/O activity.
  • One 26-pin removable field I/O termination connector with spring clamp wire retention.
Built-in I/O channels are software configurable using browser-based software groov Manage. The first 8 channels offer discrete and analog inputs and outputs; the last 2 channels offer Form C mechanical relays.

White Paper: Building Industrial IoT from Edge to Cloud

Sharing process data has long been a goal of industrial automation, but traditional operational technology (OT) architectures are poor at scaling, priced prohibitively, and demand complex configuration and support. So how can we achieve the new, more ambitious goals of the industrial internet of things (IIoT)?

Read this white paper to see how next-generation distributed I/O and control are opening new possibilities for connected infrastructure.

White Paper: I/O for the IIoT

In an era of increasing connectivity and technical capabilities, it seems like simple ideas should be simple to achieve. But industrial internet of things projects, even simple ones, are still expensive, demand special skills, and involve many steps. 

This white paper introduces edge I/O, a new kind of product that simplifies IIoT applications. Opto 22's groov RIO is an example of an edge I/O product.
