Why “DI” models deserve stricter confirmation

Models with letter prefixes (like DI3506X) are often copied from old BOMs and retyped incorrectly. Best practice is to send a label photo and—if labels are unclear—add a connector-side photo to reduce back-and-forth.

Procurement notes

• Quote exactly: DI3506X

• Include label photo (recommended)

• Connector-side photo helps when label text is incomplete or blurred

Industry Applications

DI3506X is commonly sourced in installed Triconex systems where I/O identifiers must match exactly to avoid integration questions.

Verification
