2. Product Introduction
The FC‑MCAR‑02 is a heavy‐duty 36‑inch carrier designed for the SM RIO (Remote I/O) modules in industrial automation environments. It serves both as physical mounting structure and as the electrical backplane, providing power and ground rails, mechanical support, and coupling capability. It integrates features such as cable carrier assemblies, ground rails, dual 24 V supply rails, all in a form factor suited for harsh conditions and high reliability.
This carrier is intended for mounting two IOTA‑R24 assemblies (or multiple SM RIO modules) and is built to withstand wide temperature swings, humidity, airborne pollution, and continuous industrial usage. Its robust design helps organize wiring, maintain consistent power supply, and simplify module installation and servicing.
3. Applications
-
Mounting platform in automation panels for Safety Manager RIO (SM RIO) modules.
-
Backplane / support structure for remote I/O modules, especially IOTA‑R24 type.
-
Environments requiring stable mounting and reliable power distribution to multiple modules.
-
Industrial settings with temperature extremes, moisture, or airborne contamination.
-
Process control, safety systems, power generation, water/wastewater plants, chemical plants—where modular I/O is used.
-
Retrofits or expansions: where adding SM RIO modules requires matching mounting carriers.
4. Product Advantages
-
Structural rigidity: 36‑inch metal profile able to support multiple heavy modules and cable assemblies.
-
High current capacity: 24 V DC rails capable of supplying up to 40 A, enabling heavy module loading.
-
Grounding: 32 ground connections help maintain noise immunity, safety, and proper reference potentials.
-
Environmental robustness: Wide temperature range (‑40 to +70 °C), high humidity tolerance, pollution degree 2 or better.
-
Modularity: Can be coupled with other FC‑MCAR‑02 carriers; mounting design simplifies integration and cable routing.
-
Simplifies wiring & maintenance: Backplane power rails, cover plates, cable troughs help organize wires; consistent mounting points accelerate module installation or replacement.
-
Certifications: CE and UL recognition help with regulatory compliance and safety in installations.
5. Brand
Brand: Honeywell — a global automation, control systems, and equipment supplier known for robustness, quality, and reliability in industrial and safety‑critical systems.
6. Series
Series: The FC‑MCAR‑02 belongs to the SM RIO / Remote I/O Carrier series (sometimes associated with the FSC / SM RIO family). These carriers are backplanes / physical support structures intended for SM RIO modules and related I/O assemblies. “MCAR” stands for “Mounting Carrier” (MCAR), “02” is the version number.
