| Dimensions | 152 x 185 x 82 mm |
| Operating Temp | 0 to 55 deg C |
| Power Consumption | 24 W max (1.0 A at 24 VDC nominal) |
| Display Resolution | 320 x 240 pixels (115 x 87 mm display area) |
| User Input | Analog resistive touch (128 cells, 16 columns x 8 rows) |
| Application Memory | 190 KB runtime, 240 KB nonvolatile objects/text memory |
| Network Ports | Data Highway Plus (DH+) primary, RS-232 serial printer port |

Backplane Bus Communication Velocity and EtherNet/IP Mapping
The Allen-Bradley 2711-T6C8L1 processes deterministic node transactions over its integrated Data Highway Plus (DH+) port at selectable baud rates of 57.6 kbps, 115.2 kbps, or 230.4 kbps. Onboard firmware flash compatibility permits direct memory-mapped bit writes from the 128-cell touch matrix into PLC-5 and SLC 500 data tables. Nonvolatile 240 KB system flash stores screen object layouts, alarm conditions, and static bitmap overlays, maintaining low-latency screen transitions without burdening processor scan cycles.
Frequently Asked Questions
Q: What cable and termination specifications apply to the primary DH+ communication port?
A: Connections require shielded twinaxial cable (Belden 9463, commonly termed "blue hose"). Both physical end nodes of the DH+ trunk line must be terminated with 82-ohm resistors connected across the signal pair.
Q: Is the display backlight field-replaceable, and what is its operational rating?
A: Yes, the CCF backlight assembly can be replaced in the field. It carries a rated operational half-life of 50,000 hours under standard ambient temperature conditions of 25 deg C.
Field Installation Guidelines
- Cut the mounting opening to match the required NEMA cutout dimensions, ensuring the enclosure panel is clean, flat, and deburred.
- Insert the unit into the panel cutout and tighten the rear mounting clamps in an alternating sequence to achieve uniform gasket compression.
- Connect 24 VDC nominal (18-32 VDC range) power conductors to the terminal block, ensuring proper polarity and bonding the earth terminal to the panel protective conductor.
- Ground the DH+ shield wire directly to the main cabinet ground bar at the cable entry point to minimize high-frequency noise interference.
- Maintain a minimum clearance of 50 mm around rear and side ventilation louvers to allow adequate heat dissipation up to the maximum 24 W thermal rating.
