The PanelView Standard 300 is an electronic operator interface that provides functionality with a color, grayscale or monochrome display and shows pixel graphics capabilities. The PanelView Standard 300 is available in several sizes and configurations to meet specific application requirements. All these variations improve operator productivity and simplify programming. The 2711-K3A2L1 Panelview 300 is an Allen-Bradley product that has an Operator input keypad with eight function keys (F1 to F8) and an LCD monochrome color display, with an LED backlight. It has a display dimension of 73 x 42 millimeters (2.87 x 1.67 inches), and a display resolution of 128 x 64, with a 100,000-hour, LED backlight standby life. The 2711-K3A2L1 has an irreplaceable battery, and a runtime application memory of 170 KB, which runs on a PanelBuilder32 software. It has a DH-485 (RS-232) communication pot and supports an ATA Memory card. The input voltage of the 2711-K3A2L1 is between 18 to 32 Volts DC (24 Volts DC nominal), with a maximum power consumption of 10 Watts (0.42 amps at 24 Volts DC).

With a weight of 673/1.48 grams/pounds, the 2711-K3A2L1 has a dimension of 197 x 140 x 82/7.76 x 5.53 x 3.21 millimeters/inches (length, breadth, and height). The 2711-K3A2L1 has an operating temperature between 0 to 55 degrees Celsius;(32 to 131 degrees Fahrenheit), a storage temperature between -20 to 85 degrees Celsius;(-4 to 185 degrees Fahrenheit), and a working relative humidity range between 5 to 95% noncondensing at 0 to 55 degrees Celsius; (32 to 131 degrees Fahrenheit) working temperature. It has a shock rating of 30 g, and operational vibration of 2 g. The approximate shipping weight and dimensions are 3 pounds and 11 x 8 x 6 inches and the most common Series are A and B and the most common firmware include 4.00-4.48.

The PanelView Standard Operator Terminal with catalog number 2711-K3A2L1 PanelView Standard Operator Terminal belongs to the subgroup of PanelView 300 Monochrome visualization components. This HMI features a 3-inch display screen, a single DH485 communication port and a keypad operator interface.

The 2711-K3A2L1 is visualization component, more commonly called as Human Machine Interface (HMI) in most industries. It enables operators to control and monitor the process or machine in real-time manner through a centralized and single location in the factory floor. This enables a set of operational advantages which contributes to a more efficient and increased uptime of the process or machine.

The 2711-K3A2L1 has a monochrome display screen, used for monitoring and analyzing the operation of the process. with a diagonal measurement of 3-inches. It has a display area of 73 mm (w) x 42 mm (h) or 2.87 in. (w) x 1.67 in. (h) and resolution of 128 x 64 Pixels. Through the keypad assembly which is composed of Eight (8) Function keys, cursor keys and numeric keys, operator can initiate control and modify process parameters.

The 2711-K3A2L1 HMI is powered by an external supply voltage range of 18-32V DC. It has a power consumption of 6 Watts (0.25 Amps at 24V DC) and heat dissipation of 6 Watts (13 BTU/HR).

This compact HMI may also be installed with additional modules including the interface modules for establishing connection to other industry standard communication protocol. These interface modules include Personal computer interface converter, used for converting RS-232 signals to/from DH-485 signals and an Isolated link coupler for DH-485 network. Also supported is the MicroLogix advanced interface converter module, enabling data exchange between MicroLogix controllers.
