The TU818 (3BSE069209R1) is an Original New compact module termination unit (MTU) designed for the S800 I/O distributed hardware platform by ABB. This passive base unit bridges field wiring and plug-in electronic I/O modules, accommodating a signal density of up to 1x32 or 2x16 independent terminal channels rated for an operational threshold of 50V. The unit establishes direct data bus backplane routing and localized power distribution links, eliminating separate external marshaling panels. It ensures broad cross-system integration across diverse control environments, providing backward and native hardware compatibility with 800xA, Advant OCS with Master SW, Advant OCS with MOD 300 SW, and the Compact Product Suite. Built for reliable deployment within modern fieldbus architectures, the component facilitates simple modular maintenance cycles and high signal integrity for mixed analog and discrete process applications.

Mount the termination unit onto standard 35 mm DIN rail profiles. Ensure the integrated grounding clips on the rear frame seat fully against clean, unpainted metallic tracks to achieve reliable instrument ground connection.
Align the mating interface slots of the designated S800 I/O electronic module with the base unit housing. Insert smoothly perpendicular to the rail until the latching tabs snap into position. Do not force alignment pins if resistance occurs.
Strip the field signal cabling insulation according to the specified wire gauge tolerances for S800 termination blocks. Route external field lines through dedicated lower wire trays, keeping low-voltage signal runs separated from high-capacity power lines to prevent signal cross-talk.
Verify the operational enclosure maintains structural ingress integrity against moisture accumulation and ambient dust. Ensure continuous environmental controls prevent moisture condensation inside the termination housing.
Terminate incoming field instrument cable shields at the dedicated ground bars positioned within the terminal assembly area to maintain low impedance pathways for electromagnetic interference.
What is the voltage limit specification for this termination unit?
The termination unit is officially rated to handle field distribution voltages not exceeding 50V.
How many signal lines can be terminated onto a single base block?
The module accommodates configurations of either 1x32 terminal arrangements or 2x16 split terminal pathways.
Does this MTU require internal batteries to preserve operational data?
No, this unit is a passive structural interconnection interface that contains 0 batteries.
Which I/O series is this base architecture designed for?
The unit is built specifically to host the ABB S800 I/O hardware component series.
Can this unit be integrated into legacy Advant OCS architectures?
Yes, it is fully compatible with Advant OCS with Master SW and Advant OCS with MOD 300 SW systems.
What is the physical width of this module for cabinet layout calculations?
The structural net width of the termination framework is precisely 58.5 mm.
How is electrical ground continuity established for the module?
Grounding path connectivity is automatically completed via integrated spring clips contacting the standard DIN rail system.
What should be done if the internal S800 I/O module needs replacement?
De-energize local loop channels and release the module mounting locks to pull the device straight out without dismantling field wires.
What does the 85371098 Customs Tariff Number refer to?
This identifier classifies the asset as an electrical control or distribution board, console, panel, or base assembly rated under 1000V.
Does the termination block feature conformal coating variations?
This unit corresponds to the standard catalog specification layout; specific environment variants should refer to specific suffix lists.
