Delta TP04 Operator Panels — Compact Text HMI

The TP04 series from Delta Electronics is a range of basic text operator panels with monochrome STN LCD displays. These panels are designed for applications requiring simple, reliable parameter display without a graphical interface. The lineup includes 7 models with 3-inch and 4.1-inch screens, covering needs from basic monitoring to control with built-in I/O.

TP04 Series Technical Specifications

All TP04 panels feature black-and-white STN LCD matrices with a text mode of 4 lines by 20 characters. The series is divided into two subgroups based on screen size and functionality:

  • TP04G (3" and 4.1") — classic text panels for monitoring and basic control. AS-index models have a 128x64 pixel screen (3"), AL-index models have 192x64 pixels (4.1").
  • TP04P (3") — panels with a built-in I/O module (PLC I/O), combining HMI and controller functions in a single enclosure.

Communication protocol: Modbus. Ports: RS232 (basic models), RS232 + RS422 + RS485 (extended dual-port models).

Applications

Delta TP04 text panels are used in industrial automation tasks where a graphical interface is unnecessary but real-time parameter monitoring is essential:

  • Pumping stations and ventilation — displaying pressure, flow rate, temperature; controlling operating modes.
  • Conveyor systems — speed monitoring, cycle counters, alarm messages.
  • Small machinery and packaging equipment — setting process parameters, status monitoring. TP04P models with built-in PLC are ideal for standalone machines.
  • Lighting and climate control systems — schedule timers, setpoint adjustment, event log viewing.

Other Delta Operator Panel Series

If a touchscreen graphical display is required, consider other Delta panel series: DOP-A (basic touchscreen), DOP-B (advanced touchscreen with Ethernet). The full catalog is available in the operator panels section.

Warranty and Support

All TP04 series panels come with an official Delta Electronics warranty. We provide technical support for model selection, assist with Modbus communication setup, and help connect to Delta VFDs and PLCs. Delivery across Ukraine.

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.
