ABB TU846 3BSE022460R1 Module Termination Unit – Advant OCS Series
When a termination unit fails on an ABB Advant OCS control system, the consequences cascade fast: I/O signals go dark, field devices lose their interface to the controller, and the entire process loop becomes blind. Production lines halt, alarms flood the DCS, and maintenance teams face mounting pressure to restore connectivity—often with no spare on the shelf. The TU846 is the precise hardware link between the field wiring and the ABB module rack, and without it, there is no signal path.
The ABB TU846 (catalog number 3BSE022460R1) is a dedicated Module Termination Unit engineered for the Advant OCS (Open Control System) platform—one of ABB’s most widely deployed distributed control architectures in power generation, oil & gas, pulp & paper, and chemical processing plants worldwide. Within the Advant OCS ecosystem, the TU846 serves as the passive but mission-critical wiring interface that allows I/O modules to connect cleanly to field instrumentation, ensuring signal integrity and mechanical stability across the full operating lifecycle of the control system.

Frequently Asked Questions
Q: Is the TU846 3BSE022460R1 in stock?
A: Stock availability varies. Please submit an inquiry and our team will confirm current availability and lead time within 1 business day.
Q: Can the TU846 be used as a direct replacement without reprogramming the controller?
A: Yes. The TU846 is a passive termination unit—replacing it does not require controller reprogramming. Field wiring remains connected to the termination unit while the I/O module is swapped.
Q: Do you supply both new and refurbished TU846 units?
A: Yes. We can supply new (factory-sealed), tested-refurbished, and surplus stock depending on your budget and urgency. All conditions are clearly stated in the quotation.
Q: What is the lead time for international orders?
A: Standard international shipping typically takes 5–10 business days depending on destination. Expedited options (DHL Express, FedEx Priority) are available for urgent requirements.
Q: Can you provide an ABB certificate of conformity or test report?
A: Documentation availability depends on the specific unit’s sourcing. Please specify your documentation requirements when submitting your inquiry.
Q: What if I need multiple ABB Advant OCS spare parts?
A: We welcome BOM (Bill of Materials) inquiries. Send us your full spare parts list and we will provide a consolidated quotation with availability for each line item.
