Allen-Bradley 2711C-T4T 2711 series HMI Touch Screen PanelView

The Allen-Bradley 2711C-T4T is a discontinued operator interface terminal. Here is a detailed introduction:

General Specifications

Power Supply: It requires a 24V DC power supply, which is a common power source in industrial control systems, ensuring stable operation of the device.

Enclosure Type: The enclosure type is NEMA 4X, which means it has a high level of protection against dust, water, and other environmental factors. This makes it suitable for use in harsh industrial environments, such as factories, power plants, and chemical plants.

Display and User Interface

Display: It is equipped with a 4-inch color LCD display with a resolution of 480 x 272 pixels. The display provides clear and vivid images, allowing operators to easily view process data, graphical representations, and system status information.

Touch Screen: The touch screen interface is highly responsive, enabling intuitive and convenient operation by the user. Operators can simply touch the screen to navigate through menus, access different functions, and input data, enhancing the usability and efficiency of the HMI.

Memory and Processing Capabilities

Memory: The device is equipped with a certain amount of memory to store application programs, configuration settings, and historical data. It usually has [X] MB of non-volatile memory for storing important information even during power outages, and [Y] MB of volatile memory for running applications and temporarily storing data.

Processor: It is powered by a dedicated processor that ensures fast and efficient processing of data and execution of commands. The processor is capable of handling complex HMI tasks, such as real-time data display, graphical animation, and communication with other devices in the industrial network.

Communication Interfaces

Ethernet Port: The 2711C-T4T is equipped with an Ethernet port, which allows for high-speed communication with other devices in the network. It can be easily connected to programmable logic controllers (PLCs), computers, and other industrial automation equipment, enabling seamless data exchange and integration within the overall control system.

Serial Ports: It also has serial communication ports, such as RS-232 and/or RS-485 ports. These serial ports are used for connecting to devices that require serial communication, such as older-generation industrial controllers, barcode readers, or printers. This provides flexibility in interfacing with a wide range of industrial devices.
