Panel-mounted mechanical, grounding and 24 VDC distribution base for Honeywell Safety Manager remote I/O assemblies.
FORM Panel mounted
LENGTH 36 inches
PLATFORM Safety Manager / SC
01
A structural layer, not an active module
FC-MCAR-02 provides the cabinet foundation for compatible IOTA and remote safety I/O hardware. It supports the assembly mechanically and provides shared grounding and power-distribution paths. Safety logic and channel processing remain functions of the installed active modules.

06 · BUYER FAQ
Cabinet design questions
Q
Can Honeywell FC-MCAR-02 directly replace FC-MCAR-01?
A
No. The 36-inch and 18-inch carriers require different cabinet space and mounting positions.
Q
Does Honeywell FC-MCAR-02 perform safety logic?
A
No. It is passive carrier infrastructure; active modules perform I/O processing and logic.
Q
Why is grounding critical for Honeywell FC-MCAR-02?
A
The carrier forms the shared protective-earth base; poor bonding can compromise EMC and cabinet safety.
Q
What should be checked before loading Honeywell FC-MCAR-02?
A
Check mounting alignment, earth continuity, power routing, clearances and the approved IOTA arrangement.
Q
Is 36-inch length enough to identify Honeywell FC-MCAR-02?
A
No. Match the complete model and the approved Safety Manager or Safety Manager SC cabinet layout.
