Selection Guide
Use the following criteria to confirm the SPMD1401 is the right module for your application:
- Step 1 – Identify I/O type: Confirm whether you need digital input, digital output, or mixed. The SPMD1401 supports universal configuration.
- Step 2 – Check channel count: Verify the number of I/O points required per module slot.
- Step 3 – Confirm signal voltage: Match module signal range (24VDC, 120VAC, etc.) to field device specifications.
- Step 4 – Verify DeltaV version: Ensure your DeltaV system firmware supports the SPMD1401 module revision.
- Step 5 – Check carrier compatibility: Confirm the carrier slot type in your marshalling or I/O cabinet.
- Step 6 – Contact Konmask: Our engineers can validate your BOM and recommend alternatives if the SPMD1401 is on extended lead time.
