Related Technical Topics
- Screw-Clamp RTB Wiring — The 1734-RTB screw-clamp RTB supplied with the 1734-TB accepts 0.25…2.5 mm² (24…14 AWG) single conductor or 0.75 mm² (18 AWG) twin (stranded only). Strip length 16 mm single / 18 mm twin. Terminal base screw torque is 0.8 N·m (7 lb·in).
- Removable Handoff — The RTB snaps off the terminal base for pre-wiring off the rail and for module replacement without rewiring. To reinsert the RTB, insert the end opposite the handle into the base first, then rotate the block into the base until it locks.
- 8-Terminal vs. 12-Terminal Bases — The bases a module accepts are listed in that module’s own specifications. Many 8-point modules use this 8-terminal base: the 1734-IB8/IB8K DC input modules mount on 1734-TB, -TBS, -TOP or -TOPS, and the 1734-IV8 sourcing input module on 1734-TB or -TBS. The 12-terminal 1734-TB3/-TB3S (1734-RTB3 RTB) are used only where a module’s specifications list them.
- Wire End Ferrule Compatibility — Single-conductor ferrules are supported — strip length 12.5 mm or 14.5 mm (±0.4 mm) depending on wire gauge. Consult 1734-SG001 p. 38 for the full ferrule table.
