- Documented 210 mA assembly current in the HPM planning table.
- Nonconformally coated execution with HPM redundancy and Division 2 context.
MU-PDIS12 is the nonconformally coated Honeywell HPM Digital Input Sequence of Events IOP. The reviewed HPM planning guide identifies the exact 51402625-125 part number, 32 channels and 210 mA assembly current. It also lists DISOE among the IOP types supported by redundant HPM configurations. The source table places 51402625-125 in the non-CE-compliant column and does not list a CE-compliant MU-PDIS12 part number, so compliance must not be inferred from the model name alone.
The IOP card installs in an HPM IOP card file and connects through the engineered field-termination assembly and cables. Honeywell lists MU-PDIS12 among HPM equipment approved for Division 2 operation, but the complete cabinet installation, enclosure, wiring method and site approvals remain controlling. Before replacement, record the card-file position, I/O Link address, primary or secondary role, FTA/cable identity, channel assignments, event configuration and printed hardware revision. Restore and prove the approved database after installation.
The MU-PDIS12 51402625-125 Honeywell HPM 32-Channel Digital Input Sequence of Events IOP may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).
Honeywell MU-PDIS12 51402625-125 official technical documentation and product links.
This multi-page Honeywell technical document contains the exact model and its technical data. Apply the values to the supplied type number and verify its revision before installation.
Confirm the complete MU-PDIS12 51402625-125 marking, nonconformally coated execution, printed revision and installed card-file position. The reviewed Honeywell table identifies this exact part as the non-CE-compliant entry and does not list a CE-compliant counterpart, so quotation and receiving inspection must preserve that boundary.
Record the field-termination assembly, cable identity, I/O Link address and primary or secondary role before disturbing the card. Redundant DISOE service requires the approved pair and common engineered termination path; a second card or similar digital-input model does not by itself create a qualified redundant installation.
Back up the HPM database and document channel labels, event handling and alarm logic before replacement. After installation, stimulate authorized state changes, confirm channel quality and timestamp sequence, verify alarms and permissives, and test both primary and secondary paths where redundancy is configured before returning the process to service.
