More Information

Overview Manuals IOP Function Installed Record Replacement Boundary Product Applications

Features:

  • LLMux role: Identified as a low-level multiplexer input/output processor card.
  • Channel identity: The available product record lists 16 channels.
  • HPM context: The card belongs to an installed HPM card-file and database arrangement.
MU-PLAM02 51304362-100 is a Honeywell HPM IOP card whose practical identity is defined by both model and part number.

Available data identifies 16 channels and a 70 mA assembly current at 24 VDC, but does not establish a complete suffix-level functional specification.

The installed slot, mating hardware, channel map, wiring, grounding, and HPM database should therefore be retained with the spare request.

Apter Power supports MU-PLAM02 51304362-100 enquiries with sourcing, documentation, installed-record review, and HPM configuration guidance.

  • Function: MU-PLAM02 is the Low-Level Multiplexer (LLMux) IOP card for the High-Performance Process Manager.
  • Channel capacity: The Honeywell planning reference lists 16 channels.
  • Power draw: The assembly current is listed as 70 mA from the 24 VDC system supply.
  • Part identity: 51304362-100 is the documented CE-compliant part number for the nonconformally coated MU-PLAM02.
  • Card-file position: Record the HPM chassis, card file, and slot before removal.
  • Channel allocation: Preserve field tags, ranges, wiring destinations, and database references.
  • Mating hardware: Capture connectors, termination assemblies, and cable identities associated with the installed card.
  • Area classification: Retain the cabinet and site record showing whether the installation is operated in a Division 2 location.
  • Exact identity: Match MU-PLAM02 together with Honeywell part number 51304362-100.
  • Part-number boundary: Do not substitute another MU-PLAM suffix or a similarly numbered Honeywell assembly without documented review.
  • Configuration control: Confirm card-file position, database, wiring, grounding, and field-device assignments before energization.
  • Evidence package: Keep the nameplate photograph, HPM planning reference, slot record, and channel map with the replacement file.
  • Legacy HPM I/O: Acquires low-level multiplexer signals where this exact IOP identity is specified.
  • Division 2 systems: The Honeywell planning reference lists MU-PLAM02 among approved HPM IOPs for Division 2 use.
  • Maintenance sourcing: Uses the complete model and CE part number to separate the required card from adjacent HPM hardware.
  • Migration preparation: Preserves slot, channel, wiring, and database evidence for a wider HPM modernization review.
Description
The HPM uses MU-PLAM02 51304362-100 as a 16-channel Low Level Multiplexer IOP for thermocouple and RTD signal collection. MU-PLAM02 is the model designation and 51304362-100 is the paired Honeywell part number for this card.

One supported TC or RTD field termination assembly can connect directly to MU-PLAM02 51304362-100. When an installation needs two FTAs, the architecture adds the dedicated MU-TLPA02 power adapter rather than wiring both assemblies directly to the IOP.

Card-file planning for MU-PLAM02 51304362-100 includes 70 mA from the 24 VDC assembly supply and a maximum documented 50 m run from the IOP to the power adapter. Longer field distances belong on the supported downstream FTA side of the LLMux arrangement.

Technical notes
MU-PLAM02 51304362-100 is a 16-channel low-level multiplexer IOP for supported thermocouple and RTD FTA arrangements. Honeywell lists 70 mA assembly current and direct one-FTA use; a two-FTA layout uses MU-TLPA02. Replacement planning should retain FTA type, cable topology, adapter use, channel mapping, cold-junction compensation, and HPM configuration.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
An HPM cabinet is being expanded from one to two FTAs. What changes around MU-PLAM02 51304362-100?
Add the dedicated MU-TLPA02 power adapter for the two-FTA arrangement; Honeywell documents only one supported TC or RTD FTA as a direct connection.
Can the cable from MU-PLAM02 51304362-100 to the LLMux power adapter be routed for 60 m?
No. Honeywell documents a maximum of 50 m on that segment, so the layout must be revised or the longer distance moved to a supported downstream FTA run.
Which field signals should be assigned to MU-PLAM02 51304362-100?
Use it for the supported low-level thermocouple or RTD FTA architecture. Do not treat it as a general-purpose analog input card without the matching LLMux termination hardware.
A quotation substitutes MC-PLAM02 for MU-PLAM02 51304362-100. Can it be accepted as the same card?
No automatic equivalence is established. The verified Honeywell pairing for this page is MU-PLAM02 with 51304362-100, so a different prefix needs its own part-specific confirmation.
How much HPM card-file current should be reserved for MU-PLAM02 51304362-100?
Reserve the published 70 mA from the 24 VDC assembly supply and include it with the other installed IOP loads in the card-file power budget.
Can MU-PLAM02 51304362-100 connect either a thermocouple FTA or an RTD FTA directly?
Yes, one supported TC or RTD FTA may connect directly. The exact FTA must still match the sensor type and the installed Honeywell LLMux design.
