Description

The Allen-Bradley 1794-TBN is a FLEX I/O terminal base unit designed to provide a robust wiring interface for FLEX I/O modules. This component serves as the physical connection point for field wiring, allowing for efficient installation and maintenance of industrial I/O systems. It features a compact, open-style design suitable for DIN-rail mounting within control cabinets.

Features

• 16 I/O terminals for field device connectivity
• 2 common terminals for signal distribution
• 2 positive voltage terminals for power supply distribution
• Reliable screw-clamp terminal blocks for secure wire retention
• IP20-rated enclosure for protection against solid objects
• Designed for seamless integration with the Allen-Bradley FLEX I/O platform

Installation Guidelines

• Ensure the power is disconnected from the system before installing or removing any I/O modules from the terminal base.
• Mount the 1794-TBN on a standard 35mm DIN rail. Ensure the base is securely locked into position.
• Use appropriate wire gauges as specified by local electrical codes and the FLEX I/O system manual.
• Maintain proper cable routing to minimize electromagnetic interference (EMI) from high-voltage lines.
• Verify that all screw-clamp connections are tightened to the recommended torque to prevent loose connections or intermittent signal loss.
• Handle with care to avoid damage to the backplane connector pins.
