Description
Core Product Summary
The Beijer Electronics E300 (Type 04380 / 04380A) is a compact industrial operator panel and human-machine interface (HMI) designed to monitor and control automated machinery. Built for demanding industrial and marine operating environments, this unit integrates a backlit monochrome display with a dedicated physical keypad layout to handle system interactions, parameter adjustments, and operator commands.
Engineering integration relies on built-in serial communication links, such as RS-232 and RS-422 ports, enabling direct data exchange with compatible programmable logic controllers (PLCs). The terminal runs on a standard 24 VDC power supply and incorporates robust front-panel construction suited for flush enclosure mounting in control cabinets or operator consoles.

Detailed Product Overview
The Beijer Electronics E300 (Type 04380) is an established operator interface terminal engineered to provide direct interaction with industrial automation hardware. Its architecture centers on a high-contrast backlit monochrome LCD paired with a tactile button layout, making it resilient in plant floor applications where quick, physical keystrokes are preferred.
From an integration perspective, the unit relies on serial communication channels (RS-232 and RS-422) to link with automation controllers. This makes it compatible with established controller families like the Mitsubishi MELSEC series frequently found in compact machinery and marine automation packages. Because application logic and screen layouts are software-defined via legacy development tools, deploying a replacement unit requires matching both the hardware type 04380 specification and the original compiled project file to ensure proper button mapping, alarm handling, and register communication.
Applications & System Role
The Beijer E300 functions as an intermediary visualization and input terminal within machine-level automation architectures. Rather than executing primary control logic, it interfaces directly with a connected PLC to present real-time operational data, system statuses, and error messages to the user while transmitting manual commands back to the core controller. It is frequently utilized in specialized industrial setups, discrete manufacturing cells, and marine auxiliary equipment control panels (such as incinerators or pump skids) where reliable character-based or graphical monochrome visualization is required.
