Beijer Electronics 04380A
Product Name: E300 series HMI operator panel
Introduction: Industrial human-machine interface terminal for machine visualization, operator input and PLC communication in factory, marine and process automation applications.
Technical Specifications: 24 VDC power input; approximately 0.45 A nominal draw; integrated serial communication ports with RS-232/RS-422 support where fitted; industrial front bezel and panel-mount enclosure; 0°C to 50°C operating range.
Detailed content
Functional Features: Provides process visualization, alarm display, operator input, screen navigation and serial data exchange with connected controllers; front-panel indicators and legacy configuration via Beijer programming tools.
Application Scenarios: Packaging lines, assembly machines, water treatment auxiliary skids, marine switchboards and legacy PLC panels requiring E300-compatible operator interface.
Structural Characteristics: Panel-mount HMI with front fascia, rear brackets/connectors, integrated display/input area and serial communication terminals; industrial sealed bezel for harsh cabinets.
Working Principle: The HMI receives power from 24 VDC, boots the operator runtime, communicates with PLCs through serial ports, renders screens from the project database and returns operator commands to the control system.
Installation Requirements: Install in panel cutout specified by the E300 variant; use regulated 24 VDC with correct polarity; connect serial cables with matched baud rate and protocol; verify project/firmware compatibility before transfer.
Usage Precautions: Prevent reverse polarity on DC supply; avoid excessive backlight aging by ensuring ventilation; use correct Beijer transfer cable and software version; do not power the panel with unverified serial wiring.
