2711-T5A9L1

The 2711-T5A9L1 is a PanelView 550 operator terminal from Allen-Bradley. This is an electronic device, mainly used for implementing real-time monitoring and control of a machine or industrial process. Commonly termed as Human Machine Interface (HMI), it is typically coupled with a Programmable Logic Controller (PLC) for exchanging I/O data, especially compatible with Allen-Bradley’s PLC, SLC, and Logix controller platforms. It may also be used with 3rd party products, gateways, and similar devices. The 2711-T5A9L1 is designed for flush mounting and vertical orientation only since this terminal does not support any form of screen rotation. The appropriate enclosure rating for using this terminal are NEMA Type 12/13, 4X, IP54, and IP65 rated enclosure. The appropriate enclosure cut-out to flush mount this terminal is 125 mm (H) x 165 mm (W) while recommended minimum mounting clearances are 25 mm or 1 inch for the top and side clearance and 38 mm or 1.5-inch bottom clearance for natural cooling airflow and adequate working space for wiring and maintenance. The minimum enclosure depth required for installation of this terminal is 64 mm or 2.54 inches with the standard configuration; 109 mm or 4.3 inches when installed with memory card retainer and 188 mm or 7.4 inches for insertion and removal of the memory card. This operator terminal comes with a touchscreen interface, a 5.5-inch monochrome screen with a resolution of 256 x 128 pixels, and dual RS232 ports with one functioning as the primary communication port supporting DH485 protocol while the other is intended for alarm printer communication.

The Allen-Bradley 2711-T5A9L1, a part of the PanelView 550 Terminal Series that operates using RS-232 (DH-485), and RS-232 (printer) as the communication ports. Moreover, this terminal has a 5.5-inch, 256 x 128 display resolution and a monochrome display type. The 2711-T5A9L1 has an operating temperature range of 0 - 55 deg. C and it runs on 18-32V DC or 24V DC nominal input voltage. The 2711-T5A9L1 uses a touchscreen as its input type and it has an actuation of one million presses. It has a RAM of 240 KB which store data, files, applications, and other equivalents. The 2711-T5A9L1 has a display area of 120 mm x 60 mm and a 100,000-hour LED backlight life. In addition, it consumes 18 Watts of power, weighs approximately 0.93 kg, and measures approximately 152mm x 185mm x 82mm dimension.
