Description

The ABB TU850 (Order Code: 3BSE020850R1) is a specialized expansion module base designed for the ABB S800 I/O system. This unit serves as the physical and electrical foundation for the TB850 modem module, providing a secure and reliable interface for distributed I/O applications operating at 50VDC.

Engineered for specific industrial environments, the TU850 is designed to support the TB850 modem, which facilitates communication over a 50VDC bus. This unique capability makes it an essential component for automation systems that require a robust and noise-immune communication network over longer distances.

Application Scenarios

Consider a large-scale water distribution network where control cabinets are spread out over several kilometers. In this scenario, the ABB TU850 is deployed within remote pump stations to house the TB850 communication modem.

Here, the 3BSE020850R1 plays a crucial role in system reliability. It provides the necessary 50VDC power and communication interface for the TB850 modem, ensuring stable data transmission between the remote station and the central control room. The robust design of the TU850 protects the sensitive modem electronics from the harsh environmental conditions often found in outdoor pump stations, including extreme temperatures and humidity. This unit is the silent guardian of the remote I/O system, ensuring that every piece of data from the field reaches the controller without interruption.
