TPH-LBF-IA1.36.DE.1 order guide

Use the exact manufacturer order number and verify the system constraints before procurement.

1

Select the diagnostic variant

Specify the complete .DE.1 suffix; .DE.0 does not provide the same diagnostic function.

2

Confirm the fieldbus architecture

Verify the Power Hub, trunk and intrinsic-safety method are compatible.

3

Check electrical limits

Keep the segment within the 36 V, 600 mA rating and all hazardous-area entity parameters.

4

Provide grounding

Follow the direct shield-grounding and M4/external rail instructions.

5

Allow for spur consumption

Include the protector self-consumption of up to 6 mA in the segment calculation.

6

Follow the certificates

Apply the relevant ATEX, IECEx or local approval control documentation for the installed zone.

Quotation checklist: Send the complete order number, nameplate photo, quantity, destination and required condition. Technical compatibility remains an engineering decision.
