Cost Effective Upgrade Solution
Utilities have large investments in hard wired automation systems. As a piece of equipment ages it fails more frequently, takes longer to repair, and eventually reaches the end of its life. Re-design and forklift replacements require utilities to re-engineer substation designs, replace field wiring, and re-train staff to manage and maintain the system, which is a costly endeavor.
The D.20 RIO option with support for D.20 communications provides a cost effective alternative to upgrades of legacy D20 RTUs. Simply replace the failed or end of life D20 unit with a D400 Gateway and D.20 RIO module, plug the D.20 interface cable into the D.20 RIO, connect the D.20 RIO to the D400 or an Ethernet port in the substation LAN and you are ready to add modern functionality to the D400 series of Substation Gateways including:
- Cyber security features for integration into NERC CIP environments
- Secure real time browser access
- Browser-based HMI interface
- Secure remote engineering access
- IEC 61850 capabilities
- Automatic record retrieval (fault records, SOE, settings files, any other file available in the IED)
I/O Where You Need It, Minimizing Wiring Cost
The D.20 RIO Distributed I/O Controller is a small form factor stand-alone device that supports two D.20 link channels for communication with the D20 series of input / output modules.
- Interface with standard D20 I/O (status, analog input, control and combination input) peripheral modules
- Support for up to 30 I/O modules in a single D.20 RIO, or distributed over up to four D.20 RIO devices within the substation
- Small form factor with multiple mounting options for installation flexibility: 19" Rack, panel mount or DIN Rail
Use the D.20 RIO module to install input / output modules in the substation LAN. No substation LAN? No problem, connect the optional D.20 RIO device directly to the built-in D400 Ethernet switch.

Manufacturing for the D20MX portfolio has been discontinued. Please contact GE Vernova for availability.
Multilin D20MX Substation Controller Legacy
Simple to Advanced Substation Automation Control
Manufacturing for the D20MX portfolio has been discontinued. Please contact GE Vernova for availability.
Advanced Controller
The Multilin D20MX Substation Controller collects, filters, and sorts data from a wide range of intelligent devices (RTUs, relays, meters) in the substation. The D20MX preserves original data time stamps for accurate sequence of event (SOE) logs, allowing data from large diverse geographic regions and time zones to be analyzed in extreme detail. Data can be presented simultaneously to multiple SCADA hosts. The D20MX comes with a built-in suite of protocols and security applications to facilitate integration with various substation devices and SCADA hosts.
D20MX is the sixth generation of D20 CPUs designed to provide a smooth migration path for D20 users to extend the life of aging D20 systems. It introduces a new and modern network security feature suite that enables effective compliance with NERC-CIP requirements, using open and trusted standards and protocols that allow integration with modern cyber security systems and tools.
Advanced Substation Controller Connectivity
D20MX Upgrade Process
The Multilin D20MX provides a cost-effective alternative to upgrades of legacy D20/D200 RTUs. This means that the investments made in GE Vernova’s automation systems keep paying dividends beyond their originally projected end of life. Simply replace the Multilin D20/D200 processor module with a Multilin D20MX and migrate the device configuration to extend the life of the existing D20/D200 Controller. Add cyber security features for integration into NERC-CIP environments. As technology changes with market demands, GE Vernova continues to invest in a partnership with their customers through advanced modular design principals
Integration into NERC-CIP Environments
The Multilin D20MX supports a comprehensive set of security functions to allow a seamless integration with existing IT department policies. Built-in cyber security features, such as Remote Authentication Dial-In User Service (RADIUS), Role Based Access Control (RBAC), and user activity logging, provide a complete security toolkit required to enable simpler and more efficient compliance with NERC-CIP requirements, using open and trusted standards and protocols, that allow integration with modern cyber security systems and tools.

Hardware Overview
Backwards Compatibility with Earlier Vintages of Multilin D20 RTUs
The Multilin D20MX is an embedded single board computer powered by a 667 MHz PowerQUICC II Pro processor pin-for-pin compatible unit with existing D20 Processors and accessories, such as chassis, D20 remote I/O peripherals, modems.
Fully Equipped Out-of-the-Box
Previous generations of D20/D200 RTUs required add-on system components and software to support Ethernet communications and optional memory expansion. The new D20MX is equipped by default with integrated memory, 10/100/1000BASE-TX or 100BASE-FX IEEE 802.3 compliant communications and a core load firmware with a comprehensive set of key substation automation applications.
D20 I/O options
A complete family of substation hardened I/O modules makes the D20MX controller scalable to both large and small substations. A distributed architecture with both ring and star topologies allows for easy expandability and remote placement of I/O modules. The following I/O modules are available in a variety of models with I/O ranges up to 300VDC.
