The Allen Bradley 2711-K9A5X is a classic product of Rockwell's PanelView 900 series, supporting both touchscreen operation and button control modes. Whether it's viewing flowcharts or starting/stopping equipment, it is extremely convenient. Therefore, it is highly favored in industries such as old system upgrades, water treatment, and textiles. Hanyite Automation Technology, as your reliable supplier, guarantees that the products are original and brand new. Currently, we have stock available. If you plan to purchase, we will ensure your satisfaction with the high-quality guarantee.
The Allen Bradley 2711-K9A5X is renowned for its toughness and is specifically designed to operate in harsh environments. Its casing has an exceptionally good sealing performance, reaching the NEMA 4/4X standard. It can withstand dust and oil pollution in workshops, as well as extremely humid and even water-salvageable areas. Not a drop of water can penetrate it. Additionally, it has strong anti-interference capabilities. Even if there are frequent start-stop operations of large motors nearby or severe fluctuations in the power grid, it can still work stably. If the temperature inside the cabinet is higher in summer, it won't cause it to "break down" or freeze.
If the Allen Bradley 2711-K9A5X breaks down or needs an upgrade, it's really hassle-free. You don't have to go through any major efforts. The best part is that its front panel can be detached and replaced separately. If the screen stops working, just replace the panel component. The back box and all the messy wires don't need to be moved. It's as simple as changing a phone case. Moreover, the wiring terminals on the back can be unplugged and plugged in. When replacing the machine, just pull them out before the new machine arrives and plug them in directly. You don't need to reconnect any wires. Electricians would be over the moon, significantly reducing downtime.
Q1. How about slow screen response? Is it broken?
A: It's not necessarily broken. The screens of the older PanelView models are resistive screens, and their response speed is definitely slower than the current capacitive screens (of mobile phones). You need to tap with your fingertip or nail, not press your finger belly hard, as that would make it more difficult to identify accurately. And if the program interface is too complex and there are too many logical operations, the screen refresh will also be slower, which is a normal phenomenon.
Q2. Can it support USB transmission of programs?
A: Allen Bradley 2711-K9A5X cannot directly insert a USB drive to transfer programs (this is a very old system). Program transmission is usually done through the RS-232 serial port (the nine-pin port) connected to the computer, using a dedicated transmission cable. Or use a PCMCIA card (if the slot supports it) to update.
Q3. My screen has a blank or white screen. What should I do?
A: This situation is likely due to aging backlight or loose internal wiring. This machine has been in use for many years, and backlight failures are common. You can try pressing the battery first before powering it on and restarting. If it doesn't work, it is recommended to directly replace the front panel components instead of scrapping the entire machine, which is much cheaper.
