More Information

Overview Manuals Specifications Dual-Power Planning Redundant ModuleBus TB840 Matching

Features:

  • Dual modem power: Each TB840/TB840A position has an individual 24 V feed.
  • Redundant ModuleBus: Double electrical ModuleBus connections serve redundant I/O.
  • Cluster addressing: A rotary switch selects addresses from 1 to 7.

TU848 provides a dual-power termination and addressing base for two optical ModuleBus modems connected to redundant I/O.

The separate power inputs and redundant ModuleBus paths must both be represented in the cabinet power and network drawings.

Procurement should match TU848 and 3BSE042558R1 with both modem labels, two feeds, cluster address, ModuleBus routes, and key settings.

Availability is subject to Apter Power's current inventory and sourcing confirmation.

What is ABB TU848 3BSE042558R1 used for?
It terminates two TB840/TB840A optical ModuleBus modems with redundant I/O, redundant ModuleBus, and individual power feeds.
What does dual power mean for TU848?
ABB provides one 24 V DC input for each modem position. Verify both feeds, protection devices, and cable labels.
How does TU848 differ from TU840?
Both serve redundant I/O, but TU848 has individual power for each modem while TU840 uses a single-power arrangement.
How many ModuleBus paths does TU848 use?
ABB describes double electrical ModuleBus connections and redundant I/O. Confirm both routes in the project drawing.
What cluster-address information is needed for TU848?
Record the rotary-switch setting from 1 to 7 before removal and verify it against the node documentation.
Can TU848 be assumed hot-swappable?
No. ABB lists Hot Swap as No, so use the approved isolation and replacement procedure.
Where can I get TU848 documentation and a quote?
Open the verified PDF in Manuals and provide Apter Power with both modem types, quantity, destination, condition, and required date.
