Delta TP05 — text operator panel for industrial equipment

The Delta TP05 series comprises compact text-based operator panels by Delta Electronics, designed for basic monitoring and control of industrial processes. Featuring a monochrome STN LCD display with a 3.8-inch diagonal and 160×80 pixel resolution, the TP05 delivers clear real-time text information display. The panel supports RS232, RS422, and RS485 communication interfaces via the Modbus protocol, enabling seamless integration with Delta frequency inverters, PLCs, and other automation equipment.

TP05G-BT23.8"160×80RS232 / RS422 / RS485

The TP05G-BT2 model features two communication ports, allowing simultaneous connection to multiple devices on a Modbus network. This makes it a practical solution for small-scale automation systems where real-time parameter monitoring is essential.

Delta TP05 panel applications

TP05 text panels are used in industrial systems where a graphical interface is not required and the primary task is displaying numeric values, statuses, and alarm messages:

  • Frequency inverter control — monitoring motor speed, current, and frequency
  • HVAC systems — temperature, humidity, and air pressure control
  • Pump stations — displaying pressure, fluid level, and pump status
  • Packaging equipment — cycle setup, counters, diagnostics
  • Compressor units — pressure monitoring, oil temperature, running hours

Other Delta Electronics panel series

If you need a graphical display or a larger screen, consider other Delta series:

  • Delta TP04 — text panels with 3 to 4.1-inch screens (7 models)
  • Delta DOP-A — graphical panels with TFT displays from 3.5 to 10.4 inches
  • Delta DOP-B — modern graphical panels with Ethernet support and colour screens

Warranty and support

All Delta TP05 operator panels come with an official warranty. We provide technical support, assistance in selecting the right model for your application, and consultation on connecting to Delta equipment.

Frequently Asked Questions

What is the difference between an HMI panel and a PLC?

A PLC runs the automation logic, while the HMI shows the machine state and sends operator commands to the controller or VFD. If you need I/O and control logic, use a PLC. If you need a screen with buttons, alarms and setpoints, use an HMI.

Which HMI screen size should I choose for a control cabinet?

For a simple machine, 4.3-5.7 inches is usually enough. A 7-inch panel works well for pump stations, ventilation and small machines. Choose 10.1 inches or larger when the operator needs trends, recipes, alarm logs or several mimic screens.

Does an operator panel need Ethernet?

Ethernet is useful for Modbus TCP/IP, several controllers, remote service or connection to the plant network. If the panel is next to one VFD and communicates over RS-485, Modbus RTU is often enough.

Can an HMI be connected directly to a VFD?

Yes, if the VFD supports Modbus RTU or Modbus TCP and the register map is available. For Veichi drives we often check VI20 or VI30 panels because they fit Veichi-based control cabinets well.

What information is needed to replace an old operator panel?

Send the old panel part number, cutout size, supply voltage, port type, protocol and the project file if it is available. Without the project file, the screen project often has to be rebuilt.

Can you select an HMI for a specific PLC?

Yes. Send the PLC or VFD model, required screen size and communication method. We will check the ports and suggest the series that fits the project best.
