Beijer 04380A

Product Short Description

Product Introduction

The Beijer 04380A is a dedicated industrial Human-Machine Interface (HMI) operator terminal belonging to Beijer’s E300 series. It is developed to provide intuitive and reliable interaction between on-site industrial equipment and operators, enabling convenient monitoring of equipment operating status and simple control operations. The terminal is powered by 24 VDC and is compatible with a voltage fluctuation range of 20–30 VDC, adapting well to the unstable power-supply environment typical of industrial sites. It meets Class I, Division 2, Groups A–D, T4 hazardous location standards, making it applicable to harsh industrial environments such as marine equipment and chemical plants .

Working Principle

The embedded processor runs Beijer firmware that polls field devices via serial protocols (such as Modbus RTU). It renders equipment status on the LCD display and transmits operator key-press commands back to the PLC, all as defined in the project configuration downloaded via PC software. Communication with mainstream industrial controllers such as PLCs is realized through RS232C/RS422 interfaces, enabling efficient data transmission and real-time synchronization between equipment operation data and operator instructions .

Functional Characteristics

Customizable function-key mapping to match different industrial control logic
Alarm list management with time stamping
Recipe handling and data logging to memory
Multi-language text support for global deployments
Stable data interaction for real-time synchronization of equipment operation data and operator instructions
Expansion capability via PCMCIA card slot to meet personalized functional expansion needs (e.g., Profibus-DP, DeviceNet, Ethernet, CC-Link)

Application Scenarios

Widely used in equipment control and production process monitoring across:

Manufacturing – OEM machinery, machine control
Marine Engineering – Marine propulsion controls
Petrochemical Industry – Chemical processing skids
Water Treatment – SCADA local panels
Food Processing (dry areas)
Process Control & Automation Production Lines
Logistics Equipment

Its Class I Div 2 certification makes it specifically suited for harsh industrial environments including marine and chemical hazardous areas .
