The Allen-Bradley 2711-T10C8L1 is a PanelView Standard operator terminal. This operator terminal is commonly called as a Human Machine Interface (HMI) with the primary purpose of linking data and logic within a Programmable Logic Controller (PLC), display the data via a custom designed interface and permit control via the provided input interface.

The 2711-T10C8L1 provides process visualization via the provided Active Matrix Thin-Film Resistor (TFT) with Cold Cathode Fluorescent (CCF) Backlight. This HMI screen has an effective display area of 211 x 158 mm (8.3 x 6.2 in.), resolution of 640 x 480 pixels. Embedded within the HMI screen are individual touch cells with size of 26 x 30 pixels and distributed in 24 columns x 16 rows.

The 2711-T10C8L1 communicate with partner controllers and devices via the built-in Data Highway Plus (DH+) protocol. This communication protocol is a legacy protocol that is based in RS485 topology. It allows multi-node communication over long distances. Additionally. This operator terminal has One (1) RS232 communication port that is mainly used for communicating with alarm and event printer for documentation and historization.

This operator terminal is powered by a nominal 24VDC power supply with applicable range of 18-32VDC. It has an operating temperature of 0…55 ° C (32…131 ° F) and storage temperature of -40…85 ° C (-40…185 ° F). It has a rated heat dissipation of 78 W (264 BTU/HR) with operating shock and vibration of 15 g and 1 g up to 2,000 Hz, respectively.

For industrially approved installation and maximize the unit’s lifespan, install the hardware in a NEMA Type 12/13, 4X (Indoor use only), IP54 and IP65 or any equivalent rated enclosures. Create a panel cut-out according to the cut-out template shipped with the terminal and install the hardware flush mounted to the panel. It has internal circuit protection however, external protection devices may be installed such as surge suppressors, transformer, Uninterruptible Power Supply (UPS) and other devices.

The screen has a backlight installed that has a minimum half lifespan of 50,000 hours at 25 degrees Celsius and that is also field replaceable. A 1008 KB non-volatile flash memory for application objects, bitmaps, and texts and a 310 KB application runtime memory are available with this terminal. It also supports additional memory via ATA memory cards. A real-time clock, which is battery-backed and has a user-replaceable memory, is also present and it timestamps all critical data. Two communication ports are present with this terminal and these are a DH Plus (DH+) communication port and an RS-232 printer port. The 2711-T10C8L1 terminal is a DC powered terminal with an 18 to 32 Volts DC input voltage and a 24 W maximum power consumption. Its operating temperature range is from 0 to 55 degrees Celsius and its non-operating temperature range is from -25 to 70 degrees Celsius. The terminal also has a non-condensing relative humidity of 5 to 95% at 0 to 55 degrees Celsius.
