- Bailey IMMFP and IMFEC module families (confirm pinout)
Always cross-reference the module’s installation manual to confirm cable compatibility before ordering.
Selection Guide
Use the following criteria to select the correct termination unit cable for your application:
- Step 1 – Identify your I/O module: Note the exact ABB Bailey module part number (e.g., NKIO01, NKDI02).
- Step 2 – Measure cable reach: Confirm the distance from the module connector to the field terminal block. Choose NKTU02-15 (15 cm), NKTU02-30 (30 cm), or NKTU02-60 (60 cm) accordingly.
- Step 3 – Verify connector type: Confirm the module-side connector matches the NKTU02-30 pinout from the ABB Bailey module datasheet.
- Step 4 – Check quantity: Each I/O module typically requires one termination cable. Order spares for critical loops.
- Step 5 – Contact Konmask: If uncertain, send your module part number and system documentation to support@konmask.com for a verified selection.
