Hey, look over here! The Allen Bradley 2711-K5A16 is a "veteran" in the Rockwell family's PanelView 550 series. It doesn't have the trendy touchscreen; instead, it uses a 5.5-inch monochrome screen with a row of sturdy physical buttons. Just think of it as an "industrial version of a Nokia feature phone" - rugged, durable, and with quick response! In those environments where conditions are harsh, where gloves are required for work, or where a response is needed immediately upon pressing a button, this thing is much more reliable than a touchscreen. It is the most direct and solid "communication bridge" between the operator and the machine. Therefore, when you need to purchase this classic and reliable equipment, it is crucial to find a reliable supplier. And we can guarantee that every unit we provide is original and brand new, allowing your production line to use it with peace of mind.

Operation method: |
All depends on the buttons! There is a row of function keys (F1-F10) and numeric keys. Press them and there's a "click" sound. The feel is very good, and you can operate it even with gloves on. |
|
Display screen: |
A 5.5-inch monochrome blue screen. It looks very retro, but it's clear! No matter how chaotic the workshop lighting is, you can clearly see the text on it. |
|
Communication protocol: |
Allen Bradley 2711-K5A16 only speaks two "dialects": DH-485 and Remote I/O. These are the "common language" of Rockwell PLC-5 and SLC 500 from that generation. |
|
Memory: |
There is 240K of memory. It's more than enough to store complex programs and images. |
|
Protection level: |
The front panel is protected by NEMA 4X, which basically means it's waterproof, dustproof, and resistant to corrosion. It can be left in the workshop to be freely handled. |
|
Programming software: |
You need to use a software called PanelBuilder 32 to "program" it. |
In the end, the core reason for choosing the Allen Bradley 2711-K5A16 is just one word: stability! This device is not as delicate as a touchscreen. The physical buttons can be pressed tens of thousands of times without breaking. It is such a tough character that it can keep the production line "running without interruption". Operators can operate it blindly by feeling, and they can keep their eyes on the equipment all the time. Their reactions are fast and accurate, and the efficiency is much higher than searching for buttons. Moreover, with its "steel and concrete structure", it can handle all kinds of situations such as oil stains, dust, and humid environments. It is the king of cost-effectiveness for upgrading the interface of the old PLC-5/SLC 500 system. It is reliable and practical.
The Allen Bradley 2711-K5A16 is specifically designed to solve the troublesome issues in the workshop. Previously, there were numerous buttons and indicator lights in the control panel, resembling a spider web, making it impossible to determine where to start troubleshooting when something broke; new workers would be completely confused. Now, it has centralized all the displays and operations onto one screen, making everything clear at a glance. Moreover, in those areas covered in oil and requiring gloves for work, delicate touch screens are completely ineffective, while its tough buttons can be pressed no matter how you do it, ensuring that every press is successful without any glitches. The most crucial aspect is that it can reveal the "inner thoughts" of the machine, clearly showing parameters and alarms, eliminating the need for experienced workers to guess based on their experience.
Q1. Does this screen have a USB port? Can I copy programs using a USB drive?
A: No! Buddy, this is an "oldie but goodie". There's no USB. The program needs to use the serial port (RS-232) at the bottom. You need to connect a special cable to the computer to transfer it.
Q2. My PLC is the latest ControlLogix. Can I connect it directly?
A: Direct connection? No way! They don't "speak" the same language. You need to find a "translator" (protocol conversion gateway), but this thing is expensive and troublesome. I really don't recommend doing it this way.
Q3. My screen looks very dark and I can hardly see anything. Is it about to break?
A: Don't rush to throw it away! Go to the system menu and look for "Contrast" to adjust it. See if it can be made brighter. If it still doesn't work even when it's at the maximum brightness, then maybe the backlight inside has reached the end of its lifespan. You'll need to repair it or replace it.
