Product Introduction
The Beijer Electronics E300-04380A is an operator terminal intended for machine-level visualization and control. In a typical PLC-based installation, the HMI presents operating information, alarm conditions, and control commands through a programmed operator interface. The actual functions depend on the application project loaded into the terminal and the PLC communication configuration.

E300-04380A
One documented E300 application uses the terminal with a Mitsubishi MELSEC FX2N PLC in a TeamTec GS 500C marine incinerator. That installation demonstrates the E300 family’s use in dedicated machine-control applications, but it does not establish that every -04380A unit contains the same program or supports the same PLC configuration.
For replacement projects, the original application is as important as the hardware. A replacement terminal may power up correctly while displaying no useful information or failing to communicate with the PLC if its program, serial settings, or communication driver differs from the original installation.
Application Scenarios and Field Pitfalls
Typical applications
- PLC-based industrial machine operator stations.
- Equipment status and alarm visualization.
- Marine machinery control panels.
- Local operator command interfaces.
- Legacy automation systems using serial PLC communication.
Engineering checks before replacement
- Preserve the original HMI program. Confirm whether the application project can be uploaded from the existing terminal. Do not assume a replacement arrives with the machine-specific program.
- Verify the communication interface. Check the actual RS-232 or RS-422 wiring, connector pinout, baud rate, parity, and PLC protocol.
- Match the exact type. Confirm -04380A rather than relying only on the family designation.
- Check the power supply. Provide a regulated 24 VDC source capable of supporting the terminal’s rated 450 mA requirement.
- Inspect the display and keypad. Check for LCD degradation, damaged keys, intermittent operation, and connector corrosion.
- Test with the actual PLC. A standalone power-up test cannot establish correct communication or machine-control functionality.

The -04380 and -04380A are separately listed products. Do not assume their hardware, firmware, or application compatibility without checking the nameplate and original machine documentation.
Procurement and Quality Control
is reported as discontinued by the manufacturer in industrial component records. Replacement sourcing should include hardware inspection and application-program verification.
Before purchasing, request:
- Photograph of the complete Beijer identification label.
- Confirmation of mo and type 04380A.
- Confirmation of 24 VDC power requirements.
- Front-display and keypad inspection photographs.
- Rear connector and terminal photographs.
- Firmware and application-program identification.
- Confirmation of serial communication functionality.
- Power-up and PLC communication test results.
- Clear disclosure of new old stock, unused surplus, or refurbished condition.
Replacement recommendation: Specify Beijer Electron, not simply . Confirm the original application program, PLC communication settings, and physical interface before commissioning a replacement.
