Building Resilient Switchgear with Compact and Secure Connectivity

Overview

Power equipment builders require stable output, low-latency data, and reliable remote diagnostics to prevent costly downtime. As breaker contacts and field devices become digitized for better monitoring, the network must be able to collect data in real time, support fast alerts, and maintain strong system resilience.

However, this shift also introduces cybersecurity risks such as unauthorized access and data tampering. Moxa helps bridge the IT/OT gap by enabling Modbus RTU-to-TCP conversion, secure data transmission, and isolated management traffic. With compact hardware and advanced protocol support, Moxa simplifies the creation of a secure and reliable network backbone for power applications.

System Requirements

• Digitize breaker contacts in tight cabinets to support remote diagnostics and reduce monitoring blind spots
• Enable reliable field data aggregation with real-time alerts for link failures
• Support Modbus RTU-to-TCP conversion for smoother integration of legacy serial components
• Strengthen cybersecurity with SNMPv3, TLS 1.2 encryption, and isolated management traffic
• Maintain stable and low-latency communication to reduce downtime and improve system resilience

Solution

Moxa offers a secure and space-efficient solution for modern power equipment networks. The ioLogik E1212 features an ultra-slim 27.8 mm design, making it suitable for digitizing breaker status inside space-constrained cabinets while optimizing available panel space.

For field data consolidation, the EDS-2010-ML Series provides plug-and-play connectivity and supports relay alarms to immediately notify users of link issues. This helps operators respond quickly to communication failures and maintain reliable system performance.

To protect critical power control data, the MGate MB3270-G2 supports Modbus RTU-to-TCP conversion with SNMPv3 and TLS 1.2 encryption. This enables secure integration of legacy serial devices while protecting data integrity, isolating management traffic, and reducing the risk of unauthorized access.
