PRODUCT INFORMATION
Product Overview
The Allen-Bradley 2711-K3A5L1K is a PanelView 300 Conformal Coating Keypad operator interface in the PanelView series. It features a 3-inch monochrome LCD display with an LED backlight rated for 100,000 hours. The display screen provides a resolution of 128 by 64 pixels for graphics and text. Operators interact with the unit through an integrated keypad with eight assignable function keys.
This terminal operates on a nominal 24V DC power supply ranging between 18 and 32V DC. Maximum power consumption reaches 10 Watts or 0.42 Amps at 24V DC. It includes a conformal coating layer for protection in harsh industrial operating environments. The unit communicates via an RS-232 communication port utilizing the DH-485 protocol.
