HONEYWELL FC-IOCHAS-0003R | Redundant I/O Module Chassis

📌 Product Overview

The HONEYWELL FC-IOCHAS-0003R is a chassis designed for redundant I/O modules in Honeywell Safety Manager systems. It provides the mechanical mounting, power distribution, and backplane interface required for redundant I/O modules.

Honeywell’s hardware reference identifies FC-IOCHAS-0003R as the chassis type for redundant I/O modules. The official documentation lists CE, UL, CSA, TÜV, and FM approvals and specifies a 19-inch rack-compatible chassis with a 280 mm depth.

The model is also part of Honeywell’s later IOCHAS-0003 generation. Honeywell documentation identifies FC-IOCHAS-0003R as a replacement generation for earlier FC-IOCHAS-0001R/0001S chassis and notes that additional power-distribution components may be required when integrating the newer chassis into an existing configuration.

Honeywell’s official hardware reference gives the standard chassis dimensions as 482.6 mm wide and 280 mm deep, with an official chassis weight of approximately 8.5 kg.

Some commercial listings for FC-IOCHAS-0003R show different weight and power-distribution configurations, including 6.91 kg and 9.96 kg. These differences can result from the particular chassis/backplane configuration or included hardware, so the physical unit should be checked before installation.

⚡ Power & I/O Configuration

The FC-IOCHAS-0003R is more than a simple mechanical rack. Its configuration provides power distribution and interconnection for redundant I/O modules.

Depending on the specific hardware configuration, commercial technical data identifies possible input arrangements including:

5 VDC control/backplane supply
24 VDC input
48 VDC input
110 VDC input

Corresponding output arrangements can include 24 VDC, 48 VDC, or 110 VDC distribution. The exact current and number of supported outputs depend on the particular FC-IOCHAS-0003R configuration.

For this reason, the input/output ratings printed on the actual chassis should be treated as the final reference when replacing an installed unit.

🧩 Associated Components

FS-IOB-0003R

The FS-IOB-0003R is the associated I/O backplane reference identified with the FC-IOCHAS-0003R configuration. The supplied product title specifically references the FS-IOB-0003R V1.0 backplane.

IO-0001

Honeywell’s hardware documentation references the IO-0001 I/O module family in connection with the IOCHAS-0003R chassis. The chassis provides the rack and electrical infrastructure needed for the associated I/O modules.

FC-PDB-IO05

Honeywell documentation notes that FC-PDB-IO05 is required in certain newer Safety Manager chassis integrations, particularly when connecting the newer CPCHAS-0003 generation to FC-IOCHAS-0003R/0003S chassis.

🏭 Typical Applications

The FC-IOCHAS-0003R is intended for high-reliability industrial control and safety-system installations where redundant I/O architecture is required.

Typical applications include:

Safety Instrumented Systems
Process safety monitoring
Industrial emergency shutdown systems
Oil & gas facilities
Chemical processing plants
Power generation
Industrial process control
Redundant field I/O installations
Honeywell Safety Manager system upgrades
Replacement of legacy redundant I/O chassis

The redundant architecture is useful where continued I/O availability is important and a single module or channel failure should not unnecessarily interrupt the safety system.

🔍 Identification References

Useful identification references for this chassis include:

FC-IOCHAS-0001R
FC-IOCHAS-0003S
FS-IOCHAS-0001S
FS-CPCHAS-0003
FC-PDB-IO05
IO-0001

Honeywell’s Safety Manager documentation specifically identifies FC-IOCHAS-0003R as a redundant I/O chassis and distinguishes it from the non-redundant FC-IOCHAS-0003S.

❓ Frequently Asked Questions

Q1: What is the FC-IOCHAS-0003R?
It is a Honeywell chassis for redundant I/O modules used in Safety Manager hardware configurations.

Q2: Is FC-IOCHAS-0003R an I/O module?
No. It is the chassis/backplane assembly used to mount and interconnect the associated I/O hardware.

Q3: What is FS-IOB-0003R?
FS-IOB-0003R is the associated redundant I/O backplane reference specified with this chassis configuration.

Q4: Is FC-IOCHAS-0003R the same as FC-IOCHAS-0003S?
No. The “R” version is for redundant I/O modules, while the “S” version is intended for non-redundant I/O modules. Honeywell lists them as separate chassis types.

Q5: Can FC-IOCHAS-0003R directly replace FC-IOCHAS-0001R?
Honeywell identifies the 0003 generation as the replacement generation for older chassis, but the upgrade can require additional power-distribution components. Existing system wiring and hardware configuration should therefore be checked before replacement.

Q6: What is the chassis width?
The official hardware reference specifies 482.6 mm, or 19 inches.

🧰 Installation & Maintenance Notes

Before replacing an existing chassis, verify the complete hardware configuration rather than matching only the front-panel model number.

Recommended checks include:

Confirm FC-IOCHAS-0003R model and V1.0 revision.
Verify the FS-IOB-0003R backplane configuration.
Record all I/O module positions before removal.
Check the 5 VDC and field power distribution connections.
Verify the installed power-distribution board and cables.
Inspect backplane connectors for oxidation or mechanical damage.
Check chassis grounding and rack mounting.
Confirm compatibility with the existing Safety Manager hardware revision.
Perform I/O and redundancy checks after installation.

Honeywell specifically notes additional power-distribution hardware for certain CPCHAS-0003 and IOCHAS-0003 integrations, so the existing cabinet configuration should be reviewed before commissioning.
