Product Description
The Allen-Bradley 2711C-T6T, also cataloged as the 2711C Graphic Terminal, operates as a dedicated hardware component for human-machine interface (HMI) visualization and discrete operator control within local PLC automation networks. Equipped with a 5.7-inch color active-matrix TFT display supporting a resolution of 320 x 240 pixels (QVGA) and an analog resistive touchscreen, this unit processes operator input and displays operational data via an integrated 24 VDC power interface. Physical field communications are handled through built-in Ethernet, RS-232, and RS-422/RS-485 serial communication ports.

Ethernet Protocols & Backplane Bus Interfacing
The Allen-Bradley 2711C-T6T executes firmware flash compatibility to support seamless communication across EtherNet/IP deterministic networks and point-to-point serial interfaces. Internal processing hardware optimizes data execution speed and backplane bus communication velocity when updating tag databases connected to MicroLogix, SLC 500, or CompactLogix controllers. Embedded electrical isolation guards against common-mode voltage noise during high-speed serial packet transfers across factory floor environments.
Frequently Asked Questions
Q: What is the input power supply requirement and tolerance for the terminal?
A: The terminal operates on a nominal supply voltage of 24 VDC with an acceptable operating range of 18 to 30 VDC.
Q: Can the RS-422/RS-485 serial port be used concurrently with the Ethernet port?
A: Yes, the serial and Ethernet channels function as independent physical interfaces, allowing simultaneous connection to different controllers or programming devices.
Field Installation Guidelines
Mount the unit into a panel cutout using the integrated mounting clamps to achieve a uniform perimeter seal against NEMA Type 4X (indoor) or IP65 rated enclosures. Maintain a minimum perimeter clearance of 50 mm (2 inches) on all sides to promote natural convection air cooling. Route low-voltage 24 VDC supply lines and communication cabling through separate conduits away from AC power lines or high-frequency motor drives to prevent noise coupling. Ensure the functional earth ground terminal on the power connector is securely attached to the enclosure earth ground bus.
