Siemens SEM3CONTROLLER Programmable Logic Controller

US2:SEM3CONTROLLER is Siemens’ main controller for the SEM3 Embedded Micro Metering Module system, acting as the central processing unit that coordinates data collection and communication across SEM3 meter modules within a modular energy metering cabinet. This Main Controller is designed for integration into Siemens panelboards, switchboards, PDUs, and retrofit enclosures, enabling pre-engineered energy monitoring and sub-billing implementations across commercial and industrial deployments. In typical SEM3 configurations, the US2:SEM3CONTROLLER works alongside SEM3 meter modules such as PLAMETER and PHAMETER to deliver revenue‑grade measurement data for circuits, feeders, and loads, with the SEM3 family supporting flexible communications for data retrieval and integration. The unit itself fits compactly in SEM3 enclosures, measuring about 7.38 inches by 3.38 inches by 2.2 inches, making it a space‑efficient main controller choice for small to mid‑size energy monitoring installations. The SEM3 platform is designed for scalable, modular metering within Siemens’ energy insights portfolio, and the SEM3CONTROLLER is the central hub that enables synchronized readings across modules, facilitating accurate energy usage reporting and centralized data access for energy management and sub‑metering projects.
