As a non-edge device leveraging the latest technology in microprocessors, communications and applications, the D20E I/O can be deployed within an electronic security perimeter such as with a server (e.g. D20MX or D400) or with IEDs.

The D20E can also be used to replace legacy D20 I/O modules with minimal field wiring changes. The D20E has the same termination connector and alignment as the existing D20 I/O; this makes the D20E a practical and cost-effective solution for substation RTU and automation upgrades and retrofits.
