Gigabit Media Converters — HMC-HDM-G1S
Hardened Grade Gigabit Media Converter Built for Singapore's Harshest Industrial Environments
Redundant Power. Extended Temperature. DIN-Rail Ready. Store-and-Forward Gigabit. Ready to Deploy.
Product overview
The HMC-HDM-G1S — Hardened Grade Gigabit Media Converter
The HMC-HDM-G1S is a ruggedised, industrial-grade media converter designed to bridge 10/100/1000Base-TX copper Ethernet to 1000Base-SFP fibre networks in the harshest field environments. Built with an aluminium housing rated IP40, an extended operating temperature range of -40°C to +75°C, and dual DC redundant power inputs (DC9–56V terminal block), this converter is the standard choice for industrial automation sites, offshore platforms, roadside installations, and any deployment where a commercial-grade converter is simply not an option.

Applications
Where it is deployed
Deployed across many industries where long-distance, interference-free network connectivity is required.
Industrial Automation and SCADA
Extends gigabit Ethernet from field instrumentation to SCADA infrastructure over fibre — with dual redundant power for continuous operation.
Offshore Platforms
Platform-grade hardened converter specified for salt spray, hydrocarbon exposure, vibration, and the wide temperature range of offshore field deployments.
Roadside and Outdoor Installations
Extended temperature range and wide DC input make this the correct specification for outdoor roadside cabinets exposed to Singapore's tropical climate.
Smart Factory and Manufacturing
Factory floors with electromagnetic interference from motors and drives — the Store-and-Forward processing ensures clean data integrity on the fibre uplink.
Water and Utility Networks
Remote pump stations and monitoring equipment connected to SCADA over long-distance gigabit fibre runs — MTBF >100,000 hours for unmanned sites.
Transportation Infrastructure
Trackside and tunnel communication nodes requiring DIN rail gigabit fibre uplinks with wide temperature and wide DC power range operation.
