Products Description

The 2771P-K4M20A is a Human Machine Interface (HMI) device that is part of Allen-Bradley’s Visualization components. This device is designed for use in a wide variety of applications, enabling real-time monitoring and control of machines or processes. It is typically paired with a Programmable Logic Controller (PLC), Programmable Automation Controller (PAC), especially compatible with Allen-Bradley products however, may also be used with 3rd party controllers. The 2771P-K4M20A has a 3.5-inch grayscale display with a resolution of 320 x 240 pixels and a viewing area of 77 x 58 mm (3.0 x 2.3 in.). The available operator interface to this HMI is an assembly of keypad buttons that is comprised of function keys, navigation, numeric, and confirmation buttons. Only the functions keys of the 2771P-K4M20A are fully-programmable and may accept varying assignments in reference to the active window for operational flexibility. This HMI has a total of Eight (8) Function keys. The embedded communication ports to the 2771P-K4M20A are Ethernet and RS232 interfaces. The Ethernet interface is used for networked communication, utilizing TCP I/P protocol, supporting a transmission rate of 10/100 Mbps. It can be used for longer communication distances, able to reach up to 100 meters per segment. The RS232 is used for point-to-point, short-distance communication with a maximum of 15 meters It is especially compatible for within the panel communication. Aside from the communication interface, the peripheral port interface available to this HMI device are Two (2) USB ports wherein Keyboards and mice can be attached for an alternative means of interacting with the device. These USB ports also support attaching of USB printers and removable flash drives.

2711P-K4M20A

The 2771P-K4M20A is an Allen-Bradley Human Machine Interface (HMI) that is primarily used to implement real-time process visualization and control of a connected machine or industrial application. This operator terminal allows operators and plant personnel to monitor and control the process from a convenient, central location on the factory floor. This HMI device simplifies operation, contributes to overall accuracy and efficiency, and reduces safety risks. The 2711P-K4M20A is part of the PanelView Plus operator terminal. Specifically, it is part of the PanelView Plus 400 operator terminal. It has a 3.5-inch grayscale display, with a display area of 77 x 58 millimeters (3.0 x 2.3 inches) and a resolution of 320 x 240 pixels. The available input interface to this operator terminal is an assembly of keypads that is composed of numeric and navigation keys as well as function keys that can be assigned with global and local functions. The keypad buttons are designed to be operated up to 1 million actuations with a recommended actuating force of 10-110 g. The 2711P-K4M20A supports Ethernet communication protocol via the RJ-45. It also has an RS-232 interface that is configurable for RS-232 and DH-485 communication. It also supports the attachment of USB devices such as keyboard, mouse, and UB flash drives. The 2711P-K4M20A supported mounting orientation is horizontal only as it does not support screen rotation. It must be flush mounted to an enclosure rated NEMA Type 12, 13, 4X (Indoor use only), IP54, IP65. It must be installed in an environment with an operating temperature of 0-55 °C (32 – 131 °F), operating shock of 15 g at 11 ms, and operating vibration of 10- 57 Hz, 0.012 pk-pk displacements 57-500 Hz and 2 g pk acceleration.
