Modern integrated RTU/PLCs blur this line by offering both capabilities in a single modular unit.
Cybersecurity is a critical factor driving the replacement market. As RTUs connect operational technology (OT) to external networks, they represent a significant vulnerability. New RTU solutions must incorporate advanced security features like encrypted communication, secure boot processes, and role-based access control (RBAC) to comply with regulatory standards such as NERC CIP, making security compliance a primary purchasing criterion for critical infrastructure operators.
The Electric Power Utilities sector, encompassing generation, transmission, and distribution, contributes the largest revenue share. This dominance is driven by the global transition to Smart Grids, the mandatory requirement for substation automation, and the proliferation of distributed energy resources (DERs), all of which rely fundamentally on high-reliability RTUs for real-time monitoring and control operations.
5G technology is anticipated to be a major growth driver, enabling high-speed, ultra-reliable, and low-latency communication (URLLC) for remote industrial telemetry. This capability allows RTUs to transmit large volumes of data for edge computing and facilitates time-critical applications like automated fault isolation and network synchronization, making advanced monitoring economically viable even in highly remote geographical locations.
Yes, modular RTUs are increasingly favored over conventional monolithic designs. Modular systems offer superior flexibility, allowing end-users to customize I/O density and communication interfaces to specific site requirements.
