Configuration, Programming & Use
1794-TB3S is used within the FLEX I/O platform for flex i/o terminal base unit. Customers should archive the current program or parameters, photograph field wiring, verify power and communication requirements, and record the exact slot or mechanical position before removal.
After installation, restore only a validated project or parameter set. Check diagnostics, channel status, communications and the relevant machine safety procedure before returning the asset to production.
Typical applications
Packaging, material handling, water treatment, food processing, metals, power generation, oil and gas, and maintenance of legacy production lines.
1794-TB3S Terminal-Base Selection & Wiring Check
Use the terminal base catalog number—not appearance alone—to confirm a replacement. Before removing the installed base, photograph every conductor and label, record the adjacent FLEX I/O module, and retain the existing terminal assignment for the maintenance file.
| Catalog verification | Confirm 1794-TB3S and the complete series/revision marking. |
| Module pairing | Verify that the selected FLEX I/O module is approved for this terminal-base type. |
| Field wiring | Match terminal numbers, conductor labels, field-power grouping and grounding to the validated drawing. |
| Commissioning | Check seating, wiring security and I/O status before returning the machine to service. |
Reference the current Rockwell Automation FLEX I/O terminal-base instructions and the machine-specific electrical drawings before field work.
Lifecycle & Migration Notes
Legacy status does not make visually similar modules interchangeable. Keep the exact catalog number for immediate maintenance. For modernization, evaluate the currently supported CompactLogix, Compact 5000 I/O, FLEX I/O or PowerFlex platform appropriate to the application, then validate electrical ratings, software, wiring conversion and safety requirements.
