1734-TOP POINT I/O Terminal Base 8-Position Screw Clamp | Allen-Bradley

The Original New Allen-Bradley 1734-TOP is a one-piece terminal base for the 1734 POINT I/O distributed I/O system. It provides both the physical mounting and electrical interface between POINT I/O modules and field wiring in a single integrated assembly. The 1734-TOP features 8 screw-clamp terminations with integrated field power distribution terminals, enabling field devices to receive separate power from the control logic supply. This one-piece design simplifies installation and reduces panel space requirements compared to two-piece alternatives.

Core Engineering Highlights:
8 screw-clamp terminations | One-piece integrated mounting base | Field power distribution up to 28.8V DC | 2A continuous signal current per terminal | 35mm DIN rail mounting | IP20 enclosure | –20°C to +55°C operating temperature | 12-22 AWG wire range (0.5-2.5 mm²)
