What Opto 22 does

Opto 22 is a privately held, family- and employee-owned industrial automation manufacturer founded in 1974 and headquartered in Temecula, California. The company designs and produces programmable automation controllers (groov EPIC), edge I/O modules (groov RIO, including the EMU energy-monitoring variant), solid-state relays, and the legacy SNAP PAC System, alongside configuration and visualization software. Its hardware is used to acquire signals, control equipment, and bridge field devices to higher-level SCADA/MES systems in process and discrete industries including water/wastewater, oil & gas, food & beverage, manufacturing, agriculture, pharmaceutical, aerospace, data center, nuclear, and energy.

The underlying technology centers on an edge-oriented architecture: the groov EPIC combines a Linux-based processor with multiprotocol I/O and a built-in operator interface, allowing data to be processed locally and published to cloud or on-prem systems over MQTT, OPC UA, or vendor stacks such as Ignition (via Cirrus Link and Inductive Automation). Opto 22 has invested in formal partnerships with HiveMQ, Cirrus Link, Inductive Automation, Corso Systems, and the Eclipse Foundation to ensure its controllers fit inside open IIoT toolchains, and it holds UL Hazardous Locations and ATEX certifications for use in explosive atmospheres.

Opto 22 monetizes primarily through hardware sales (controllers, I/O, relays), supplemented by software and a lifetime guarantee on I/O modules. Go-to-market combines direct online and phone sales, an authorized distributor network, and the OptoPartners system integrator program that extends reach into mid-market and enterprise projects. Pricing spans roughly $8 for individual I/O channels to about $2,750 for a fully equipped groov EPIC processor, supporting both retrofit and greenfield project economics. Customer concentration is broad across verticals, with no publicly disclosed anchor accounts, and the company does not disclose revenue, funding history, or detailed financials.

Core offering

Opto 22 designs, manufactures, and sells industrial automation hardware and software, with the groov EPIC edge programmable industrial controller and groov RIO edge I/O modules at the center of its portfolio. Products combine real-time I/O sensing and control with modern IIoT connectivity (MQTT/Sparkplug B, OPC UA, Modbus/TCP) and built-in cybersecurity. The portfolio also includes the legacy SNAP PAC System, SNAP I/O modules, solid-state relays, power monitoring modules, and companion software (PAC Project, groov View, groov Manage). All products are designed, manufactured, and supported at the company's Temecula, California factory.

Product overview

Opto 22 offers an industrial automation and IIoT product portfolio centered on the groov family (groov EPIC edge programmable industrial controllers and groov RIO edge I/O modules), complemented by the legacy SNAP PAC System. groov EPIC serves as the core edge computing platform combining control, visualization, and connectivity with multiple programming options (Node-RED, CODESYS IEC 61131-3, PAC Control). groov RIO provides compact, intelligent edge I/O with universal signal configuration. The ecosystem includes groov View for HMI, groov Manage for device management, power monitoring modules (EMU for RIO, PM modules for EPIC), and SNAP I/O for expanded I/O needs. Supporting products include solid state relays, development tools, learning centers, and cloud connectivity via MQTT/Sparkplug B. The architecture supports both traditional automation and modern IIoT applications with built-in cybersecurity, open protocols (OPC UA, Modbus/TCP), and IT-friendly data formats.
