More Information

Overview Manuals Carrier Construction IOTA-R24 Mounting IOTA-NR24 Capacity Power-Rail Coupling

Features:

  • 36-inch panel-mounted IOTA carrier
  • 24 VDC supply rail rated up to 40 A
  • Thirty-two M5 grounding positions along the carrier
FC-MCAR-02 provides the mechanical base that aligns multiple Safety Manager IOTA positions across a control-panel installation.

The carrier also distributes the 24 VDC supply path and protective-ground connection points needed by the mounted hardware.

Its panel-mounted construction requires full-length enclosure support and deliberate cable routing rather than DIN-rail placement.

The Honeywell FC-MCAR-02 36-inch Panel-Mounted IOTA Carrier is listed as Active / Available from OEM. FC-MCAR-02 quotation requests and available Honeywell manufacturer documentation can be reviewed through Apter Power.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

What the FC-MCAR-02 Combines on One Base

  • Mechanical frame: The 36-inch carrier combines a cable-carrier assembly, metal profile, and two plastic cover plates.
  • Ground distribution: Its ground rail provides 32 screw positions for the mounted IOTA assemblies.
  • Power distribution: Separate +24 V and 0 V rails provide the common supply path along the carrier.
  • Surface mounting: Four mounting holes secure the carrier to a flat, rigid installation surface.

Securing Two IOTA-R24 Assemblies

  • Carrier capacity: One FC-MCAR-02 is arranged to carry two IOTA-R24 assemblies.
  • Ground fastening: Each IOTA-R24 is secured through ten ground-screw positions on the carrier.
  • Power fastening: Two additional connections bring 24 V and COM from the carrier rails to each assembly.
  • Replacement control: Record the installed position and field-cable mapping before removal so the two assemblies are not interchanged.

Arranging IOTA-NR24 Units on FC-MCAR-02

  • Supported count: The carrier can accommodate up to three IOTA-NR24 units.
  • Ground points: Each IOTA-NR24 uses eight ground-screw positions on the carrier ground rail.
  • Power points: Two power connections per unit link 24 V and COM to the shared rails.
  • Population check: Confirm unit count, spacing, and cable routing before adding or replacing an IOTA-NR24.

Extending Power Between FC-MCAR-02 Carriers

  • Adjacent carriers: The power rails of two FC-MCAR-02 carriers can be coupled to extend the distribution path.
  • Coupling hardware: The documented connection uses two M5 screws through the 5 mm rail holes.
  • Polarity control: Keep +24 V and 0 V rails correctly paired and verify continuity before energizing the connected carriers.
  • Grounding boundary: Power-rail coupling does not replace the protective grounding connections required for each carrier and mounted assembly.
Description
The Honeywell FC-MCAR-02 36-inch Panel-Mounted IOTA Carrier is the mechanical and distribution base for a row of Safety Manager IOTAs, keeping multiple interface positions aligned on one rigid cabinet assembly.

Across its 931.8 mm length, FC-MCAR-02 defines the IOTA position order, panel attachment points, field-cable access, and the relationship between each mounted assembly and its termination. Preserving that order during replacement avoids moving a field connection to the wrong hardware position.

Two M5 supply connections feed the 24 VDC rail on FC-MCAR-02, while repeated M5 points distribute protective grounding close to the installed IOTAs. Actual loading belongs to the fitted IOTAs and field circuits, so power, ground, and cable routing must be reviewed as one installed arrangement.

Technical notes
FC-MCAR-02 is the 36-inch panel carrier; verify enclosure clearance, M5 supply and ground terminations, mechanical support, and the 40 A rail limit.

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.
What confirms an FC-MCAR-02 installation is ready for service?
An FC-MCAR-02 installation is ready only after mechanical fastening, clearances, IOTA seating, power distribution, grounding, cable restraint, and Safety Manager diagnostics have all been checked.
Why can modules on FC-MCAR-02 lose power together?
Because FC-MCAR-02 distributes shared carrier power, a supply, fuse, connector, wiring, or grounding problem can affect multiple mounted assemblies even when the individual IOTAs are serviceable.
How should grounding be checked after installing FC-MCAR-02?
After installing FC-MCAR-02, verify the protective and functional ground paths, carrier bonding, power polarity, connector seating, and absence of unintended voltage differences before energizing the cabinet.
What should be documented before replacing Honeywell FC-MCAR-02?
Before an FC-MCAR-02 replacement, record the carrier label, mounted IOTAs, slot use, 24 VDC distribution, grounding points, cable routing, panel clearances, and Safety Manager cabinet layout.
Can FC-MCAR-02 be replaced without reviewing the installed IOTAs?
No. The FC-MCAR-02 replacement plan should include IOTA positions, connector access, field wiring support, power isolation, grounding, and the safe removal sequence for every mounted assembly.
