CGI’s Remote Telemetry Units (RTUs), also commonly known as Remote Terminal Units, form a key part of our Supervisory Control and Data Acquisition (SCADA) offering in the Australian market.
They are extensively proven across Australian electricity transmission and distribution networks, providing flexibility and scalability to help support businesses in their transition to an intelligent grid. With our local manufacturing partner, we design, build and support each RTU device, and can customise the units to suit specific needs.
Our RTUs are uniquely Australian, designed in Sydney and built in Brisbane specifically for rugged Australian conditions.
The MD Series is a range of intelligent, flexible RTUs designed for operation in the harsh environments of electricity substations and other industrial or plant conditions. Capable of interfacing with protection relays, metering systems and sensor equipment, the series is equally viable in stand-alone telemetry or sensor-rich IoT deployments.
With an integrated IEC 61131-3 soft PLC (programmable logic controller), support for industry-standard protocols and security aligned to IEC 62443-4-2, the MD Series can operate as an IED/PLC, an edge compute platform or a powerful, secure IoT device.
Our highly configurable range includes the modular, small footprint MD100m unit and extends to the rack mountable MD303cpu and MD300io-r units that are more suited to powerful control logic and intelligent processing.

- Processing capability can be added through the PM302 processor module option (standalone RTU)
- Compatible with legacy MD1000 RTU, allowing fast and cost-effective replacement installation
Empowering smarter, more resilient infrastructure with Australian-made RTU solutions
With over 35 years of experience, we help organisations improve the utilisation, condition monitoring, and automation of key assets.
Our RTUs support integration with SCADA systems and align with IEC standards, including IEC 61850, providing secure and reliable operations across energy networks and substations.
They enable smarter energy management through predictive modelling, remote diagnostics, and control of distributed energy resources (DERs), including community batteries.
Backed by local support and global expertise, we empower utilities to optimise performance, reduce downtime, and transition confidently to intelligent energy systems.
