Allen-Bradley 1785-L60B/C identifies a Series C PLC-5/60 programmable-controller processor. It provides 64K words of user memory with battery-backed static RAM. The processor has four channels configurable for DH+ or Universal Remote I/O service. A separate serial interface supports RS-232-C, RS-422-A or RS-423-A operation. It is a single-slot processor installed in the left-most position of a local 1771 I/O chassis.
The 1785-L60B/C supports existing PLC-5 machine and process-control installations with local and networked I/O. Channel assignments determine which links carry controller messaging and which service remote I/O. Complementary addressing has specific module and address requirements that must be preserved during maintenance. The processor is distinct from an extended-local or ControlNet PLC-5 variant. Before replacement, verify the installed hardware series, application memory, communication configuration and program backup.
Maintain a PLC-5/60 installation using the processor-resident local 1771 I/O chassis and its existing application program.
Assign the supported communication channels to DH+ where the control system exchanges messages with other compatible stations.
Configure Universal Remote I/O channels as required for the installed scanner or adapter arrangement, while observing total and per-link chassis limits.
It requires compatible module pairs with duplicate addresses, such as output modules sharing an output image or an input/output pair complementing one another. It is not an unrestricted increase in physical I/O capacity.
No. The PLC-5/60 configuration uses DH+ and Universal Remote I/O channels; an extended-local processor is a different configuration.
The supported channels are configurable as DH+ or Universal Remote I/O. For Remote I/O, use the scanner or adapter role required by the application.
A per-link allowance does not override the processor total. Check the complete installation against both limits rather than adding individual link capacities without regard to the total.
EEPROM is an optional program-backup medium. The processor operating-memory type remains battery-backed static RAM.
The single-slot processor belongs in the left-most slot of the local I/O chassis. A remote chassis uses the appropriate I/O adapter in its processor-side position instead.
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.
