ABB-published connector, supply, channel, environmental and mounting values.
Terminal-unit functions, serial connection and removable interface architecture in one coordinated view.
Product-specific guidance for interface selection, panel wiring, maintenance and sourcing.
ABB specifies TU509 for AC500 and S500 communication interface modules. The selected interface documentation must be checked because its function determines most terminal assignments.
The connector is the documented network connection for serial communication, including the PROFIBUS arrangement shown in ABB's TU509 guidance.
UP is routed through terminals 2.8 and 3.8, UP3 through 4.8, and the shared zero potential through 2.9, 3.9 and 4.9.
ABB lists TU509, order code 1SAP211000R0001, in the Active lifecycle phase. Quotation timing should still be confirmed for the required quantity.
ABB's TU509 data sheet does not identify one universal successor. TU510 changes the terminal technology to spring terminals, so wiring practice must be reviewed before substitution.
Send the TU509 nameplate, inserted communication-interface model, serial network type, quantity, destination and required delivery date so documentation and supply scope can be matched.

A Russian customer urgently needed a replacement for a discontinued automation component. After reviewing the product label, technical parameters, and application details, our engineers recommended a compatible alternative and provided photos and test videos before shipment. The alternative performed well, enhancing the customer's confidence in our technical capabilities and leading to multiple repeat orders.
An Indian customer still had doubts after initial online communication with us, so they visited our company in person for a face-to-face meeting and product inspection. This visit increased the customer's trust and led to the successful placement of their first order. Over the next few years, we completed multiple orders and established a stable, long-term partnership.
A Venezuelan customer needed a specific automation component and compared products and services from several suppliers online. After nearly three weeks of careful consideration, our sincere communication, professional service, and reliable product quality won the customer's trust. After receiving the product and using it for several weeks without any problems, the customer gave us positive feedback and subsequently placed multiple orders.
