Before selecting an alternative, confirm its dimensions, terminals and installation requirements in the manufacturer documentation.
Where it sits in the control system
The 1734-TB3 is the device-level element in an Allen-Bradley I/O module installation. It receives the field signals and control supply listed above — 24 V DC (IEC 61131-2) — and switches or conditions the load within the the rated ratings shown in the Specifications table. Wiring and protective devices are sized to those same numbers, not to a generic assumption.
Typical installations place it in packaging machines, conveyor transfer cells, small process skids, where the unit is matched to the original catalog number and the enclosure provides 35 mm DIN rail (IEC 60715) support. Record the catalog number and revision from the nameplate of the installed unit before specifying a like-for-like spare.
Selection notes for Allen-Bradley 1734-TB3
