Allen-Bradley 1785-LT/B identifies a Classic PLC-5/15 processor in Series B. Standard user memory is 6 K words. Supported memory expansion increases capacity to 10 K or 14 K words. The processor provides a DH+ port and a remote I/O port. Its backplane current load is 2.5 A.
The 1785-LT/B executes the control program for a legacy PLC-5 installation. The remote I/O interface can be configured for scanner or adapter operation. Program organization and I/O addressing must match the existing application. Retain a verified program backup before changing the processor. Check the hardware series, memory arrangement and communication configuration during replacement planning.
The processor evaluates the application program and updates the control data associated with the installed I/O system.
The remote I/O channel can operate as a scanner or adapter. The selected role determines how it exchanges data with the surrounding control system.
DH+ supports communication within the legacy controller installation. Addressing and network settings must agree with the existing system.
It identifies the hardware series. Check the actual processor label and the application requirements before replacement.
No. The 1785-LT belongs to the Classic PLC-5/15 family.
No. Preserve and verify the application backup and the required memory arrangement before commissioning a replacement.
Yes. Scanner and adapter operation serve different data paths, so the installed configuration must be retained.

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.
We supply leading automation brands covering PLCs, DCS, I/O modules, drives, motors, power supplies, communication modules, and more.
Our experienced team provides reliable pre-sales and after-sales support, helping customers select suitable products and resolve purchasing concerns.
Relevant datasheets and technical literature can be provided with the goods, offering useful information for product identification, installation, operation, and maintenance.
We understand the importance of minimizing equipment downtime. Our team responds promptly to inquiries and provides professional assistance with product information, quotations, order status, shipping, and after-sales questions.
Most products are covered by a warranty of up to 12 months, subject to the applicable terms and conditions. If any product-related issue occurs during the warranty period, our team will assist you and provide an appropriate solution.
We continue to source discontinued, obsolete, and hard-to-find automation parts from various brands, helping customers maintain existing equipment and reduce downtime caused by spare parts shortages.
