TU818 availability, lead time and order review
Send RFQProduct Introduction
TU818 is the compact 32-channel S800 I/O module termination unit. It provides field-signal termination and connects a supported I/O module to ModuleBus on DIN rail.
Engineering note: ABB documents TU818 as a 50 V MTU with 32 signal terminals. Keep the installed terminal map and the active I/O module definition together during replacement work.

Compatibility & Replacement
Confirmed module relationship. ABB lists TU818 as an approved module termination unit for the 32-channel DI818 digital input module.
Selection control. Do not infer compatibility with every 32-channel S800 module. Confirm the active module and the approved MTU list in the relevant ABB data sheet.
Applications & Fault Scenarios
Panel-space maintenance
Its compact format helps preserve a dense S800 I/O layout during a planned module or base replacement.
Half-bank of signals lost
Compare the 2 × 16 terminal groups with the drawings and check common field-power and return wiring before changing electronics.
All 32 channels unavailable
Check I/O-module seating, ModuleBus connection and the controller hardware definition for the station.
Wrong point mapping after outage
Verify every terminal number against the saved cable schedule; a shifted 32-point landing can create widespread false states.
Independent spare-parts support
Amikon can review the exact part number, installed system, quantity, destination and required date before quotation.
Pre-outage checkpoints
- Export or print the 32-point terminal schedule.
- Confirm the installed active module is officially approved for TU818.
- Label both 16-point terminal groups before disconnection.
- Check ModuleBus seating and channel status after restoration.

TU818 FAQ
Should the installed I/O module be confirmed before buying ABB TU818?
Yes. A 32-channel count is not enough by itself. Share the exact installed I/O module and verify the approved MTU relationship in ABB documentation before placing the order.
Why should an ABB TU818 buyer provide the article number and label photo?
They help distinguish the exact hardware identity from visually similar termination units and allow the quotation to be reviewed against the requested model.
Can current stock, condition and lead time for ABB TU818 be confirmed from this page?
No. Stock, condition, inspection scope and lead time change by offer and must be confirmed in the live quotation for ABB TU818.
What pre-shipment evidence can I request for ABB TU818?
Request clear label, condition and serial-number photos plus the agreed inspection or testing record for ABB TU818 before dispatch.
How should I submit an urgent shutdown requirement for ABB TU818?
Send the exact part number, quantity, destination, required date, machine or system model and failure context. Priority routing starts after the ABB TU818 identity is confirmed.
What DOA, return and warranty terms apply to ABB TU818?
They are defined in the quotation. If ABB TU818 arrives DOA or does not match the purchase order, report the serial number, label, packaging and fault evidence promptly for after-sales review.
