Allen-Bradley 2711-K5A3L1 is a PanelView Standard 550 operator terminal with keypad input and a monochrome blue-mode LCD. Its display provides a 256 x 128 pixel workspace for machine graphics and messages. The terminal connects to a DH-485 control network and includes a separate RS-232 printer port. The L1 configuration uses a nominal 24 V DC supply, with an allowable input range of 18-30 V DC. Ten function keys support the operator actions assigned in the application.
The 2711-K5A3L1 provides a local interface for monitoring machine conditions and entering operating commands. PanelBuilder32 is used to develop the terminal application. Numeric entry and navigation keys complement the function-key area. A battery-backed clock supports time-stamped application data. The combination of a tactile keypad and graphic display suits maintenance of established PanelView Standard installations.
Present equipment status and application screens while operators use the keypad to enter commands and setpoints.
Display application alarm information at the machine, allowing operators to review conditions through the configured screens.
Maintain a keypad-based operator station in an existing DH-485 installation while preserving the correct terminal application and network configuration.
No. This catalog configuration communicates over DH-485; an RJ-style connector must not be assumed to be an Ethernet interface.
Use the PanelBuilder32 application prepared for the PanelView Standard terminal. A PanelView Plus runtime is not the same application format.
No. It is the keypad configuration, with numeric, navigation and function keys for application operation.
It supports configured serial printing. It does not change the terminal's DH-485 controller-network configuration.
Yes. The battery is field replaceable. Follow the terminal maintenance procedure and preserve application data before servicing.
We confirm the quoted hardware condition and application suitability, inspect the unit before dispatch, and release confirmed stock after payment. A 12-month supplier warranty applies under the agreed terms.
Company was founded in Xiamen, Fujian, China, in 2005 with a team of only four people. At that time, we mainly served selected European and North American markets, supplying commonly requested industrial automation products from Siemens, Allen-Bradley and Bently Nevada. Although the business was still developing and we completed relatively few orders, this period helped us build essential product knowledge and international trade experience.
By 2017, our team had grown to approximately 30 people, and we had established a warehouse for in-stock automation components. Our business expanded across Europe, North America and Southeast Asia, while our product range grew from popular models to scarce and discontinued industrial automation parts. As our product knowledge and service experience increased, we completed nearly 20 orders per month on average.
Today, Company serves customers worldwide with a professional team of approximately 60 people. Our warehouse holds a broad selection of industrial automation components, including popular products, hard-to-find parts and discontinued models. We now complete more than 30 orders per month, with an average monthly transaction value of approximately USD 3 million. We have established long-term partnerships with nearly 30 customers from different countries and welcomed almost 40 international customers to visit our company.
Since our company was founded, we have served every customer with sincerity and professionalism. Our prices may not always be the lowest, but we earn long-term trust through quality products, dependable after-sales support, honest condition reporting, timely communication and responsible delivery. Our goal is to build lasting partnerships rather than pursue one-off transactions.
Our team members have an average of more than 10 years of industry experience. We have worked with customers worldwide, including those from India, Germany, Sweden, Italy, Russia, Venezuela, Israel, and many other countries. Throughout our careers, we have collectively completed over 3,000 orders and established long-term business relationships with customers across nearly 30 countries.
We can often identify a product’s manufacturer, series, configuration, and function from its model number or nameplate photo. We also understand how revisions, firmware, and specifications affect compatibility and whether an alternative model can be used safely.
An Indian customer urgently needed a discontinued control module after several suppliers reported no stock. We identified its exact revision and function from the nameplate, checked compatible alternatives, and contacted factory and warehouse channels to locate matching inventory. After installation, the customer confirmed that the module operated correctly and later asked us to source additional spare parts.
Our team treats every inquiry sincerely and answers every question patiently. Even for complex requests, we verify and respond to each detail instead of providing a rushed or uncertain answer.
A German customer sent a mixed list of automation products and asked repeated questions about revisions, condition, photos, and delivery. Our team organized the requirements, checked every item, and replied point by point. The customer said our detailed communication made the purchasing decision easier and continued sending us new inquiries.
