MC-HPFX02 51304362-175 Honeywell 15-Slot Card File Assembly

Configured for multi-module backplane bus power distribution and I/O card housing in Experion PKS and TPS DCS platforms, the Honeywell 51304362-175 (MC-HPFX02 15-Slot Card File Assembly) provides direct physical/electrical execution.

Hardware Specifications

Process Control & Channel Isolation

The MC-HPFX02 card file assembly establishes backplane power distribution and signal routing across 15 hardware slots, connecting analog, digital, and specialty I/O modules to system controllers. Supporting 4-20 mA HART loop protocol architectures, the backplane structure maintains physical channel-to-channel isolation between adjacent module slots, suppressing common-mode bus noise and ground potential shifts across redundant controller and power supply configurations.

Frequently Asked Questions

Q: How does the MC-HPFX02 backplane accommodate redundant power supplies?

A: The internal bus structure incorporates dual power input paths that accept independent 24 VDC feeds, maintaining card file operation if one power module drops offline.

Q: What module types can be installed into the 15 available slots on the MC-HPFX02 assembly?

A: The card file houses Honeywell analog input/output, digital I/O, pulse input, and dedicated serial communication cards compatible with TPS and Experion PKS platforms.

Q: Can modules be inserted into the card file while the assembly is energized?

A: Module replacement must adhere to Honeywell live-insertion guidelines for the specific controller platform to prevent transient power surges on the internal bus lines.

Field Installation Guidelines

1. Mount the MC-HPFX02 card file assembly securely onto the cabinet frame using panel screws, torquing fasteners to 1.5 Nm to maintain frame grounding.
2. Route primary and redundant 24 VDC power bus cables to the backplane input terminals, verifying correct polarity before applying power.
3. Connect the main frame earthing strap directly to the cabinet ground bar using heavy-gauge copper grounding wire to minimize EMI interference.
4. Verify that module guide rails are free of debris and insert I/O cards firmly until retaining latches click into place.
