The Autonics LP-A104 series is an all-in-one logic panel that seamlessly integrates the functions of a PLC, HMI, and I/O modules into a single, compact device. Designed for space-saving installation and simplified wiring, the LP-A104 delivers powerful control capabilities with a vibrant 10.4-inch TFT true color LCD display, making it an ideal solution for a wide range of machine automation applications.

All-in-One Design and I/O Configuration

The LP-A104 series provides a complete control solution in one unit, eliminating the need for separate PLCs, HMIs, and I/O modules. It is equipped with 32 digital inputs and 32 digital outputs, offering ample connectivity for mid-scale machine control tasks. The inputs feature photocoupler isolation with a response time of 0.5ms, while the outputs provide sink-type transistor outputs with a maximum load current of 0.1A per point. The integrated design significantly reduces panel space requirements and simplifies system wiring and commissioning.

Display and User Interface

The LP-A104 features a 10.4-inch TFT color LCD with a resolution of 800×600 pixels and support for up to 16,777,216 colors, delivering crisp and vibrant visuals. The analog resistive touchscreen allows operation with bare hands, gloved fingers, or a stylus, ensuring reliable interaction in diverse industrial environments. The display offers a wide viewing angle and a backlight life cycle of ≥50,000 hours. The unit can be installed horizontally or vertically, providing installation flexibility to accommodate different panel layouts and user preferences.

Communication and Expandability

Connectivity is a key strength of the LP-A104 series. It supports a comprehensive range of communication interfaces, including RS232C, RS422, USB Host (Type A) and Device (mini-B), Ethernet (10/100Base-T), and CAN. The CAN interface, equipped with a 24V CAN transceiver, allows the LP-A104 to function as a CANopen master device, enabling seamless integration with up to 16 slave devices such as Autonics ARD series and ARIO (DeviceNet models) I/O modules. A Micro SD card slot supports external storage up to 32GB for data logging and program backup.

Programming and Software Ecosystem

Autonics provides dedicated software tools for programming and screen development. The atLogic software is a ladder logic programming environment for creating, editing, and debugging control programs. The atDesigner software is a screen editor for designing the user interface, managing tags, and configuring project settings. The LP-A104 also supports advanced features such as the Bypass function, which allows ladder programs to be uploaded and downloaded via the HMI without a direct PC connection, and the Mirroring function, which synchronizes two LP-A units for real-time monitoring and redundant control. Built-in motion control and high-speed counting functions further extend its application capabilities.

Applications

The Autonics LP-A104 series is ideally suited for a variety of industrial automation applications, including:

• Packaging machinery and container sealing equipment
• Material handling and conveyor systems
• Plastic injection molding and auxiliary equipment
• Textile machinery and printing equipment
• Small to mid-scale machine control and process automation
