Company | LRI Industrial Automation

Who we are

LRI Industrial Automation is a Brazilian electronic engineering company founded in the 1990s [validate exact founding year], focused on the design, manufacturing and support of equipment for DC power monitoring, power conversion and system integration in critical industrial environments. The company was built on two convictions that still drive every project: industrial equipment must not fail silently, and cybersecurity in automation stopped being optional at least a decade ago.

The operation combines an in-house team in electronic hardware engineering, embedded firmware, test automation and field support. The portfolio includes proprietary product families, currently led by the AEM-60DC8 battery bank monitor, alongside custom projects for telecom operators, substation integrators, panel builders and large private industrial accounts.

LRI is not a reseller. Every branded product leaves Brazilian labs with hardware, firmware, testing and calibration documented internally. This vertical control is what backs the public commitment to Secure by Design, the long-term maintenance promise and the ability to absorb specific customer requirements without negotiating with a foreign headquarters.

Mission

LRI's mission is to make reliable industrial engineering and cybersecurity available to Brazilian operators, integrators and industries, without the imported-brand markup and without compromising technical criteria. In practice this means equipment that survives the real environment (electrical transients, industrial temperature, vibration, dust), traceable maintenance channels, technical documentation that respects the reader, and software architectures that do not treat security as a marketing item.

This mission translates into three verifiable commitments: a minimum 10-year life cycle for proprietary products, with spare parts and firmware support; complete and versioned Modbus documentation available to integrators from the commercial proposal onward; and incremental adherence to IEC 62443-4-2 on every new product, with a published compliance matrix.

Areas of operation

LRI operates on three technical fronts that share the same hardware and firmware competencies.

DC power monitoring. The AEM family, currently led by the AEM-60DC8 (v1.03, 147 Modbus RTU holding registers), targets stationary battery banks in telecom sites, substation control rooms, data centers and industrial plants. Equipment with per-string reading, configurable alarms, local logging and integration via Modbus RTU as a slave.

Power conversion and conditioning. Industrial DC-DC converters, redundant panel supplies, auxiliary protection and metering modules. A line historically developed to complement the installed base of telecom rectifiers and specific substation demands.

Custom solutions. Built-to-order projects for customers with requirements outside the catalog: hardware integrated to a specific SCADA, testing in compliance with a customer standard, mechanical variants for special panels, or modules combining DC measurement with proprietary communications. This branch keeps the engineering team in direct contact with the real customer problem.

Headquarters and operation

LRI runs two operations in Brazil. The technical headquarters in São Paulo hosts the electronic engineering team, the test lab and pre-sales support. The Porto Alegre operation concentrates complementary engineering, integration and support activities for the South of Brazil and parts of the Southern Cone.

The arrangement is not redundancy; each unit has a different operational focus. São Paulo handles most national telecom and industrial accounts, while Porto Alegre offers physical proximity to southern customers and to part of the supply chain for components, plastics and machining. Both units run on the same firmware version control, the same FAT process and the same firmware signing keys. There is no parallel firmware and no uncoordinated production chain.

The current headcount is approximately [validate exact number] employees, with a predominantly technical profile (electronic engineers, firmware engineers, lab and operations technicians).

Secure by Design commitment

LRI invests in IEC 62443 because the Brazilian industrial cybersecurity landscape has shifted irreversibly. Telecom operators are now embedding explicit requirements for firmware signing, anti-rollback and documented threat models into tenders and supply agreements. The electric utility sector already treats cybersecurity as a regulatory item. Industries with critical processes are following the same path.

Adopting Secure by Design in a DC monitoring product, traditionally seen as a harmless peripheral, is an engineering decision. A compromised monitor on a telecom site can mask exhausted bank alarms, fake telemetry to the NOC and, in the worst case, serve as a lateral entry into the management network. LRI considers this attack vector real and treated the AEM-60DC8 as a relevant edge device for the security of the operation.

Concretely this meant a dedicated Ed25519 key burned to OTP on the SoC; a bootloader that validates the signature and anti-rollback counter before executing any firmware; A/B partitioning with automatic fallback; and a documented holding register map with no hidden registers. The AEM-60DC8 security whitepaper documents the compliance matrix against the relevant subset of IEC 62443-4-2 SL2 [validate final version].

The next step on the internal roadmap is to extend the same set of practices to the rest of the product line and to custom projects.

Partnerships and distribution

LRI operates directly on technical supply contracts with telecom operators and industry in Brazil, and through partners for capillary distribution in specific regions and export markets.

In 2026 a partnership was formalized with Teracom Brasil [validate legal name and final scope of the agreement] to expand distribution of the AEM line in regional telecom accounts and into other Latin American countries. The agreement covers technical training of the Teracom team, an installed demonstration base and joint post-sale support, without changing the direct channel LRI maintains with national corporate customers.

Other partnerships include electrical panel integrators, substation automation specialists and accredited calibration labs [validate current public list]. LRI does not work with non-technical resellers: every partner must demonstrate the minimum competence to install, commission and provide first-level support.

Team and culture

LRI's technical culture rests on three internal premises. First, equipment ships working and working well; documentation, testing and calibration are part of the product, not an optional annex. Second, automation of internal processes has freed the engineering team for non-trivial work: firmware build pipeline, automated testing, FAT scripts and internal tooling are developed with the same rigor as a product. Third, senior engineers still write code and still open the oscilloscope; architecture without bench contact does not hold up.

The current team combines electronic engineers with long experience in industrial hardware, embedded C firmware developers with critical-systems background, test and calibration staff, field technical support, and the minimum administrative structure required. There is no inflated marketing team: technical communication is handled by engineering itself, and the website is part of that work.

LRI invests in regular internal training on IEC 62443, secure boot, automated testing techniques and modern firmware versioning practices. The premise is that applied cybersecurity is not a certificate on the wall: it is a daily practice.

How to contact

LRI prefers direct technical conversations. For proposals, integration questions, custom project requirements, equipment demonstrations or post-sales support, the official channels are:

• Sales email: [email protected]
• Technical email: [email protected]
• São Paulo phone: [validate current main line]
• Porto Alegre phone: [validate current main line]
• Web form: aem.lri.com.br/contact

For integrators and operators, the technical team responds to Modbus specifications, holding register maps, FAT and SAT requirements, and customization proposals without commercial intermediaries.
