Features:
- Thirty-two 24 Vdc digital-input channels
- Compression terminals in a C-size FTA
- CE-compliant nonconformal HPM assembly
The FTA provides the field-terminal layer for a high-density HPM digital-input path.
Its 408 mA assembly demand is part of the cabinet 24 Vdc power calculation.
Terminal style and exact material number separate it from other TDID variants with the same signal class.
Apter Power supports Honeywell MU-TDID12 51304441-125 32-Channel 24 Vdc Digital Input Field Termination Assembly with technical documents, quotations and application review.

Important Notice: Confirm the complete model, hardware revision and installed-system arrangement before use.
- Discrete status path: Thirty-two 24 Vdc channels receive on/off field states for the HPM digital-input processor.
- Processor choice: MU-PDIX02 supports standard digital-input service, while MU-PDIS12 adds the sequence-of-events path.
- Isolation boundary: Honeywell lists 1500 Vac/Vdc optical isolation for the documented externally powered field circuit.
- Response timing: The published filter and isolation delay provides a defined input response boundary for permissive and alarm logic.
- Event processor: MU-PDIS12 uses the same FTA to capture sequence-of-events information from thirty-two discrete inputs.
- Trip chronology: Ordered state changes help operators reconstruct the progression of shutdown, permissive and alarm signals after an event.
- Standard input mode: MU-PDIX02 uses the FTA for ordinary digital status acquisition when SOE ordering is not required.
- Channel continuity: The compression-terminal schedule keeps each field contact associated with its intended HPM event or status point.
- Approved context: Honeywell lists MU-TDID12 for Division 2 HPM equipment when the complete cabinet and field circuit meet the published conditions.
- Compression interface: Field conductors land on the TDID12 compression terminals defined by the installed HPM drawings.
- C-size assembly: The larger FTA format accommodates the thirty-two-channel input density within the HPM cabinet layout.
- Noncoated construction: The MU version is used where the documented cabinet design calls for nonconformally coated hardware.
- Valve position monitoring: Collect open, closed and travel-limit contacts for HPM interlock and sequence logic.
- Motor status feedback: Bring starter, contactor and running feedback into permissive, alarm and shutdown functions.
- Trip chronology: Pair the FTA with MU-PDIS12 when discrete trip and alarm transitions need sequence-of-events ordering.
- Division 2 status circuits: Acquire 24 Vdc field states in HPM installations that follow Honeywell's published Division 2 conditions.
