Related Technical Topics
- Screw-Clamp RTB Wiring — Screw-clamp RTBs (1734-RTB, -RTB3) accept 0.25…2.5 mm² (24…14 AWG) single conductor or 0.75 mm² (18 AWG) twin. Strip length 16 mm single / 18 mm twin. Torque the terminal screw firmly — manual does not specify a calibrated value for screw-clamp terminals.
- Removable Handoff — The RTB snaps off the terminal base for pre-wiring off the rail and for module replacement without rewiring. Orient the RTB correctly — the retention clip is at the top.
- 12-Position RTB (1734-RTB3) — Use the 12-position RTB for 8-point digital I/O modules (1734-IB8K, 1734-IV8, etc.) and high-density analog modules. The 8-position RTB (1734-RTB) fits 2- and 4-point modules.
- Wire End Ferrule Compatibility — Single-conductor ferrules are supported — strip lengths 12.5…14 mm depending on wire gauge. Consult 1734-SG001 p. 38 for the full ferrule table.
