The 1794-TB2 terminal base unit serves as a vital foundation for your distributed control system. This Allen-Bradley component provides reliable signal termination for FLEX I/O modules. Its cage clamp design ensures secure and durable wire connections in demanding industrial environments. You can mount this unit on either a panel or a standard DIN rail for flexible system layout.
Product Procurement & Buyer Guide
Procurement managers require components that guarantee system interoperability and robust performance. The 1794-TB2 meets these demands with its versatile voltage rating of 125V DC/AC at 10A. This unit supports both 24V and 120V power systems, simplifying your inventory needs. Its UL listing and CSA certification verify compliance with strict safety standards for global operations.
This terminal base integrates seamlessly with a wide range of FLEX I/O modules. You can use it with analog input modules like the 1794-IE8 or digital output modules such as the 1794-OB16P. This compatibility reduces the complexity of matching hardware for new or retrofit projects. The open-type enclosure design allows for straightforward integration into existing control panels.

Step-by-Step Installation Guide
Begin by selecting a clean, vibration-free mounting location for your 1794-TB2. The unit measures 94 x 94 x 69 mm, which provides a compact footprint for dense panel layouts. Secure the base to a DIN rail using the integrated locking latch for a tool-less installation. Alternatively, use the provided panel-mounting holes for a permanent fixture.
For signal wiring, you must use stranded copper wire between 24 and 16 AWG with 3/64-inch insulation. Strip the insulation carefully before inserting the wire into the cage clamp. Apply a screw torque of exactly 0.56 to 0.79 Nm to each terminal to ensure a gas-tight connection without damaging the conductor.

You must lock the key switch into the correct position for your specific I/O module. Insert the module locking latch to secure the component firmly in place. Connect the male and female FlexBus connectors properly to establish communication across the I/O bank. Always verify the isolation voltage, which depends entirely on the inserted module itself.
