Description
Pepperl+Fuchs HD2-DM-B is a basic diagnostic module for FieldConnex Power Hub systems. It monitors four FOUNDATION Fieldbus H1 or PROFIBUS PA segments and reports physical-layer supply faults through front-panel indicators and a normally closed fault contact.
The module operates from 19.2 to 35 V DC with a rated current of 20 mA and maximum power dissipation of 0.5 W. Its DIN-rail system installation supports Zone 2 or Division 2 applications when the documented Power Hub components, wiring practices, and approvals are observed.

Features:
- Basic diagnostic module for four fieldbus segments
- FOUNDATION Fieldbus H1 and PROFIBUS PA support
- 19.2 to 35 V DC rated supply
- LED indication with normally closed fault contact
- DIN-rail system mounting for Zone 2 or Division 2 installations
The module draws 20 mA and dissipates no more than 0.5 W. Correct Power Hub placement, supply wiring, grounding, segment configuration, and hazardous-area documentation are required for reliable operation.
HD2-DM-B Pepperl+Fuchs: Verify the 19.2 to 35 V DC supply, diagnostic-module slot, segment wiring, fault-contact routing, grounding, and applicable approvals before commissioning.

- Detection of fieldbus output undervoltage
- Supervision of redundant bulk power supplies
- Remote signaling of physical-layer faults
HD2-DM-B supports continuous diagnostic supervision in FieldConnex Power Hub installations. Application engineering must confirm the dedicated diagnostic-module position, monitored segment configuration, fault-contact routing, and documented hazardous-area requirements.
HD2-DM-B is intended for documented Pepperl+Fuchs FieldConnex Power Hub motherboards that provide a dedicated Diagnostic Module slot. It supports physical-layer diagnostics for FOUNDATION Fieldbus H1 and PROFIBUS PA segments. Confirm the motherboard revision, power-module arrangement, terminal configuration, and hazardous-area approval before installation.
Pepperl+Fuchs official documentation identifies HD2-DM-B as the basic diagnostic module for FieldConnex Power Hub systems. Before replacement, record the complete catalog number, isolate power where required, preserve segment and fault-contact wiring, and confirm the replacement module is approved for the installed motherboard and hazardous-area configuration. Do not substitute a different diagnostic module solely because its connector or dimensions appear similar.

Technical notes
Use HD2-DM-B only in a documented FieldConnex Power Hub diagnostic-module position. Isolate power where required, verify the 19.2 to 35 V DC supply, confirm segment wiring and fault-contact routing, and observe the applicable Zone 2 or Division 2 installation requirements before commissioning or replacement.
