Shihlin Electric EC2000 Series Operator Panels

The EC2000 series by Shihlin Electric is a range of industrial-grade graphic touchscreen operator panels featuring colour TFT displays. These panels are designed for building intuitive human-machine interfaces (HMI) in process automation systems. With support for RS232, RS422, RS485 serial interfaces and Ethernet, the EC2000 ensures reliable communication with PLCs, variable frequency drives, and other industrial equipment.

The EC2000 stands out through its combination of competitive pricing, extensive communication ports, and 65,536-colour support. Displays with 800x480 pixel resolution provide clear rendering of process diagrams, trend charts, and alarm messages even under bright industrial lighting conditions.

EC2000 Series Technical Specifications

All EC2000 series models are built on a TFT matrix platform with 65,536-colour reproduction and feature USB host and client ports for project download and data exchange. Key technical parameters:

  • Display type: graphic touchscreen TFT, 65,536 colours
  • Resolution: 800x480 pixels
  • Screen sizes: 7 inches or 10.2 inches
  • Serial interfaces: RS232, RS422, RS485
  • Network interface: Ethernet (CT11 models)
  • Protocols: Modbus RTU/ASCII, Modbus TCP/IP
  • USB: host + client

Models with the CT11 suffix additionally feature an Ethernet port for connecting to TCP/IP industrial networks. This enables remote equipment monitoring and integration into SCADA systems without additional gateways.

Application Areas

EC2000 operator panels are widely used across various industrial automation sectors:

  • Conveyor systems -- speed visualisation, sensor status, and alarm monitoring
  • Pump stations -- pressure, flow rate, and VFD operating mode control
  • Ventilation equipment -- temperature, humidity, and schedule monitoring
  • Packaging lines -- recipe management and production counters
  • Compressor units -- pressure and oil temperature parameter display

Modbus RTU protocol support ensures compatibility with Kinco panels, controllers, and variable frequency drives from most manufacturers.

Other Shihlin Electric Panel Series

In addition to the EC2000, Shihlin Electric offers the EU2000 series with 5.7-inch and 10.4-inch screen sizes. For projects requiring a smaller screen or budget-friendly solution, consider also browsing Delta Electronics panels and Schneider Electric panels.

Warranty and Support

All EC2000 series operator panels are supplied with official manufacturer warranty. Our team provides technical support for connection, communication protocol setup, and visualisation screen programming.

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.
