Overview

The Honeywell 9202‑ETS‑HN3 Eaton Modbus Module is a specialized industrial security appliance built on Eaton’s MTL 9202‑ETS Tofino™ platform. It provides advanced firewall and intrusion protection for Modbus networks, safeguarding distributed control systems (DCS), PLCs, and SCADA infrastructures against cyber vulnerabilities. Designed for plug-and-protect installation, it requires no pre‑configuration or disruption to existing control systems, making it easy to deploy and maintain.

This appliance is recognized for improving system reliability, stability, and cybersecurity, while reducing downtime and maintenance costs. Additionally, it supports compliance with industry cybersecurity standards such as NERC, ANSI/ISA, and ATEX Zone 2 hazardous location certifications, making it ideal for deployment in petrochemical, refining, and power generation facilities.

Technical Data

Typical Applications

• Cybersecurity protection for Modbus communication in distributed control systems.

• Securing SCADA networks in petrochemical and refining plants.

• Protecting power generation facilities from cyber intrusions.

• For instance, many industrial operators deploy the 9202‑ETS‑HN3 to isolate critical Modbus traffic and enforce firewall rules without disrupting operations.

• Chemical processing plants rely on it to meet regulatory compliance while maintaining uptime.
