2711-K5A20L1

The Allen-Bradley standard Operator Terminal with catalog number 2711-K5A20L1 is a Human Machine Interface (HMI) device that allows machine users and plant operators to monitor and control an application real-time, within a central and convenient location.

The 2711-K5A20L1 is powered by an external supply 24 VDC nominal voltage with applicable range of 18-32VDC. It has a power consumption of 18 W, max (0.75 A @ 24V DC). This operator terminal has an operating temperature of 0…55 ° C (32…131 ° F), operating vibration of 2 g up to 2,000 Hz and operating shock of 30 g/50 g. Installs this operator terminal flush mounted to an enclosure with protection ratings of NEMA Type 12/13, 4X (Indoor use only), IP54, IP65. Additionally, install appropriate climate control devices such as fan and heater to maintain the required operating temperature and with reference to the operator terminal’s heat dissipation such as 20 W (69 BTU/HR).

This operator terminal has a dedicated Ethernet port that enables this HMI to perform data exchanges over Ethernet network. It supports multi-node communication and may be used with industrial rated or commercially rated networking components such as RJ45 connector, LAN cable and ethernet switches. The individual RS232 port may be used to communicate with alarm and events printers for historization and documentation of process and system alarms and events.

The 2711-K5A20L1 is provided with 5.5-inch display. Keypad inputs area consisting of Ten (10) function keys, numeric input, navigation and cursor control buttons that are capable of up to 1 million actuations. It also has a Random Access Memory (RAM) of 170KB and 240KB non-volatile memory.

An Ethernet/IP Communication Port, RS-232 Printer Port, Standard Ethernet Communication cable, memory card slot, and spare bulb holder are also located on the back, along with a cover that supplies access to the replaceable backlight lamp. This internal backlight illuminates the LCD display by conveying light through a fiber-optic bundle, and its replacement part number is 2711-NL1. The 2711-K5A20L1 takes 24V DC power and can be mounted via the sealing gasket lacing the backside of the terminal. To complement its impressive features, the PanelView 550 is small and easy to ship, with a convenient 6 lbs weight and 14 x 11 x 18 in dimensions.
