Honeywell CC-MCARW1 Experion PKS Series-C Carrier Channel Assembly

Configured for secure hardware interfacing and power routing in Experion PKS Series-C subsystems, the Honeywell CC-MCARW1 (CC-MCARW1 GI/IS Carrier Channel Assembly) provides direct physical/electrical execution.

Hardware Specifications

Channel-to-Channel Isolation and Intrinsic Safety Power Distribution

The Honeywell CC-MCARW1 provides dedicated physical bus termination pathways and isolated voltage bus routing across all connected I/O channels. Designed to isolate hazardous field circuits from core backplane logic, the board maintains intrinsic safety parameters without compromising signal resolution. Integrated G3 conformal coating defends onboard trace geometries from corrosive environmental agents, preventing current leakage across adjacent channels under high ambient humidity.

Frequently Asked Questions

Q: Can the CC-MCARW1 carrier be mounted in hazardous field locations?

A: Yes, the assembly is certified for installation in Class I, Division 2, IECEx Zone 2, and ATEX Zone 2 hazardous areas when housed within an appropriately rated enclosure.

Q: Is field wiring connected directly to the carrier board assembly?

A: Field connections interface via standard Series-C I/O termination blocks mounted directly onto the carrier assembly channels, allowing pre-wiring prior to module insertion.

Q: Does replacing a carrier assembly require turning off power to adjacent field circuits?

A: Carrier replacements require isolation of main power feeds supplying the specific carrier backplane to ensure safe physical disconnection from active power rails.

Field Installation Guidelines

1. Mount the carrier assembly securely onto the cabinet backplate using standard industrial hardware, verifying that all ground bonding points establish solid metal-to-metal electrical contact.
2. Ensure low-voltage intrinsic safety (IS) cables are routed through distinct raceways separated from non-IS field wiring and high-voltage AC conductors.
3. Terminate signal cable shield drain wires at the designated system ground bus bar inside the enclosure to eliminate ground loops and reduce electromagnetic noise.
4. Verify that power supply polarities and field circuit voltage ratings strictly match hardware requirements before energizing the subsystem.
5. Maintain clear vertical and horizontal clearance around the assembly to permit adequate convective air circulation across the board face.
