Descripción Reseñas

The 2711-K5A20L1 is a compact, DC-powered human-machine interface (HMI) unit belonging to the Allen-Bradley PanelView 550 Standard series. Designed for robust machine-level visualization, this terminal facilitates real-time process monitoring and direct interaction with programmable logic controllers (PLCs). It is engineered for 24 VDC industrial environments, providing a reliable alternative to traditional physical switch panels in applications such as automotive assembly, water processing, and material handling.

Communication and Memory

This unit features a dual-interface architecture to support both network connectivity and peripheral logging. The primary communication port is an integrated Ethernet interface, enabling low-latency data exchange over EtherNet/IP architectures. A secondary RS-232 serial port is provided for dedicated printer output or firmware updates. The terminal includes 170 KB of application runtime RAM and 240 KB of non-volatile memory, with an integrated PCMCIA ATA slot available for expanded storage, recipe management, and data logging.

Features

Integrated membrane keypad with 10 assignable function keys (F1-F10), numeric input, and navigation clusters.
5.5-inch monochrome transflective LCD (blue mode) with long-life LED backlight.
Field-serviceable backlight (MTBF 100,000 hours).
Hardware-based real-time clock (RTC) for precise event time-stamping.
Status diagnostics via dedicated COMM (green) and Fault (red) LEDs.
NEMA 12, 13, 4X and IP54/IP65 environmental ratings for indoor industrial use.

Installation Guidelines

Ensure the panel cutout is clean and free of burrs to maintain the integrity of the NEMA/IP seal.
Use appropriate shielded Ethernet cabling to minimize EMI in high-noise industrial environments.
Verify that the 24 VDC power supply is within the 18-32 VDC range before connection to prevent damage.
Maintain adequate clearance around the unit for ventilation and access to the PCMCIA slot.
Always power down the terminal before inserting or removing PCMCIA cards or performing wiring maintenance.
Ensure proper grounding of the chassis to the control cabinet frame to reduce electrical interference.
