POINTBus Backplane Communication Velocity and Deterministic Networks
- The Allen-Bradley 1734-TBCJC provides direct passthrough pathways for POINTBus power and communication lines across EtherNet/IP deterministic networks.
- Embedded cold junction compensation (CJC) hardware interfaces exclusively with the 1734-IT2I Thermocouple Input Module to ensure precise signal scaling.
- An adjustable mechanical keying mechanism prevents improper module insertion, maintaining system I/O density scaling and hardware integrity.
- Terminal pin layout provides structured assignments: Terminal 3 for Shield, Terminals 4/5 for 1+/1-, and Terminals 6/7 for 0+/0-.
Frequently Asked Questions
Q: Which specific I/O module is compatible with the 1734-TBCJC wiring base assembly?
A: The 1734-TBCJC is designed exclusively for pairing with the Allen-Bradley 1734-IT2I POINT I/O Thermocouple Input Module.
Q: How does the mechanical keying feature on the 1734-TBCJC function?
A: The base contains an adjustable orange mechanical key that must be rotated to the specific position corresponding to the intended module to prevent incorrect hardware insertion.
Field Installation Guidelines
Position the 1734-TBCJC vertically above the adjacent module or adapter, aligning the interlocking side pieces. Slide the unit down and press firmly against the 35 mm DIN rail until the mounting base snaps into place. Ensure the DIN rail locking screw is set to a horizontal position and verify that a zinc-plated chromate steel DIN rail is used to establish reliable ground continuity. Wire thermocouple leads using 24 to 14 AWG conductors, securing no more than two conductors per terminal pin. Torque terminal block screws strictly to 0.5-0.6 N m.
