Selection Guide
Use the following criteria to select the correct 1492 cable for your application:
- Step 1 — Identify your I/O module: Confirm the Rockwell Automation module series (1756 / 1769 / 1794 / 1746).
- Step 2 — Determine cable length: Measure the distance between the I/O module and the terminal block. Choose 0.25 m, 0.50 m, or 1.00 m accordingly.
- Step 3 — Confirm connector style: Match the TBCH, Type A, or Type D connector to your interface module catalog number.
- Step 4 — Check I/O point count: Verify the cable supports the required number of I/O points (16-point or 32-point variants available).
- Step 5 — Verify certifications: Ensure CE/UL compliance meets your regional installation requirements.
