Product Description
The Allen-Bradley 2711-K9A1 is a PanelView 900 HMI operator terminal designed for real-time process monitoring and control across various industries. This 9-inch monochrome graphic display (640 x 400 pixels, AC Gas Plasma) interfaces with PLCs, gateways, and converters to visually represent process data. It features a keypad with numeric, function, and cursor keys for operator input. Communication is facilitated via Remote I/O (RIO) for network connectivity and RS232 for alarm printing and application file transfer. Powered by 120V AC (85-264V AC range, 47-63 Hz, 110 VA max), the 2711-K9A1 allows operators to monitor information, execute applications, and control processes within the logic controller.
Is Your Device Showing These Signs?
The Allen Bradley 2711-K9A1 Human-Machine Interface (HMI) commonly experiences issues such as a failed backlight, resulting in a dim or unreadable display, requiring backlight replacement. Touchscreen unresponsiveness or inaccurate calibration necessitates touchscreen repair or recalibration. Communication failures with the PLC are traced to faulty communication ports or incorrect communication protocol settings, demanding port repair or configuration adjustments. Corrupted firmware leads to operational errors, necessitating firmware reflashing or a memory module replacement. Power supply failures cause complete unit inoperability, requiring power supply repair or replacement.
Technical specifications
The Allen-Bradley 2711-K9A1 is a PanelView 900 Standard Operator Terminal HMI featuring a 9-inch AC Gas Plasma Monochrome display with a 640 x 400 pixel resolution and a viewable screen area of 210 x 131 mm (8.27 x 5.17 in.). Input is via a 14-button numeric keypad (0-9, -, ., Enter, Backspace), 16 User-Defined Function Keys (F1-F16), and cursor keys. Communication ports include a Remote I/O (RIO) Communication Port (supporting daisy-chain topology) for connecting to RIO scanners or sub-scanners with configurable parameters via the initial power-up screen, and an RS-232 Printer Port (supporting IBM enhanced character set) for alarm reporting, event historization, and application file transfer. It operates on a 120V AC power supply with a voltage range of 85-264V AC and a frequency of 47-63 Hz, consuming a maximum of 110 VA. Compatible with Programmable Logic Controllers (PLCs), it is designed for process monitoring and control via panel mounting, retaining settings between power cycles.
Our Repair Process for the
2711-K9A1
Our repair process for the Allen Bradley 2711-K9A1 HMI begins with a comprehensive diagnostic evaluation to pinpoint the failure. Backlight failures are resolved through direct backlight replacement, restoring screen visibility. Touchscreen issues undergo precise recalibration, and component-level repairs are performed if unresponsiveness persists. Communication failures are addressed by thoroughly inspecting and repairing communication ports, followed by verification of correct communication protocol settings. Firmware corruption necessitates immediate reflashing or replacement of the memory module to restore proper operation. Power supply failures are rectified through component-level repair or complete power supply replacement, ensuring the unit receives proper power.
