More Information

Overview Manuals Specifications RTB Transfer Review Terminal Preparation Product Applications

Features:

  • Two-part assembly: 1734-MB mounting base and 1734-RTB form the catalog assembly
  • Removable wiring: the screw-clamp RTB detaches from the base for controlled service
  • Eight positions: independent terminal locations support the installed POINT I/O module
1734-TB is intended for POINT I/O service strategies that preserve field wiring on a removable screw-clamp block.

The detachable RTB changes the maintenance path, but it does not remove the need to inspect conductors, clamps, labels, and latching.

Correct mechanical keying and DIN-rail seating remain essential when the base and wired block are reassembled.

Availability of 1734-TB is subject to Apter Power inventory and sourcing confirmation.

Assess the removable terminal block

  • Identity: verify the wired block is the screw-clamp 1734-RTB.
  • Condition: inspect the handle, housing, screws, and conductor entries.
  • Records: preserve terminal labels and the original channel map.
  • Reinsertion: confirm the curved end and handle latch engage the base correctly.

Rebuild a reliable screw connection

  • Wire range: keep copper conductors within the published limits.
  • Ferrules: match sleeve and strip lengths to the official table.
  • Torque: apply 0.8 N·m without damaging the terminal.
  • Functional check: test every transferred circuit after latching the RTB.

Supported product applications

  • Remote I/O maintenance: retain field wiring during approved base replacement.
  • Screw-terminal cabinets: use an eight-position removable RTB for POINT I/O signals.
  • DIN-rail stations: mount compatible modules through the keyed base assembly.
  • Documented spares: support service plans that preserve a verified wired terminal block.
Description
A 1734-TB assembly combines the 1734-MB mounting base with the eight-position 1734-RTB removable terminal block. Its screw-clamp RTB separates field wiring from the DIN-rail base during an approved maintenance procedure.

The removable block on 1734-TB can preserve labeled conductors while the mounting base is serviced, provided its clamps, insulation, handle, and keying remain suitable. Rockwell Automation specifies the applicable wire range, ferrule preparation, and 0.8 N·m terminal torque.

Before reusing an existing RTB with 1734-TB, technicians should document terminal assignments and inspect the block rather than treating removal as proof of condition. Base seating, module keying, field power, and post-service channel checks complete the return-to-service review.

Technical notes
A removable RTB creates the specific service risk for 1734-TB: a wired block can be transferred even when its screws, handle, or insulation are unsuitable. Reuse depends on conductor preparation, 0.8 N·m torque, terminal labels, base keying, field-power limits, and positive latching.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
When may the wired 1734-RTB from 1734-TB remain in service during base replacement?
Only after de-energized removal and inspection confirms the block, clamps, handle, labels, insulation, and conductors remain suitable.
How does 1734-TB change the rewiring scope compared with a one-piece screw base?
Its eight-position RTB detaches from the mounting base, so approved field wiring can remain on the inspected block.
What should be investigated if a channel becomes intermittent after 1734-TB is reassembled?
Review RTB latching, screw torque, conductor retention, terminal alignment, field power, module seating, and the specific circuit path.
Can a spring-clamp block be fitted to 1734-TB without further review?
The catalog assembly specifies the screw-clamp 1734-RTB; changing the terminal method requires explicit official compatibility and wiring evidence.
Which maintenance records should accompany a stored 1734-TB assembly?
Keep the catalog identity, RTB condition, terminal map, compatible module position, keying, field-voltage class, and inspection date.
Why must 1734-TB be de-energized even when only the removable block is handled?
The RTB can carry field voltage, and insertion or removal under power can create shock, arcing, or unintended machine operation.
