Product Description – Honeywell FC-IOCHAS-0002R A.R.T. Chassis for Redundant I/O CC
The Honeywell FC-IOCHAS-0002R is a high-integrity, industrial-grade I/O chassis engineered to house up to 9 pairs of redundant I/O modules. Designed specifically for integration within Honeywell’s Safety Manager Advanced Redundancy Technology (A.R.T.) systems, this 19-inch rack-mountable chassis ensures modular flexibility, optimal cable management, and fault-tolerant operation.
It comprises a mechanical housing, cover plates, two IO-0002 extender modules, and a blind plate for the unused slot. The chassis supports 21 module slots—of which slots 1 through 18 are allocated for I/O modules configured in redundant pairs. Slot 19 contains a horizontal I/O bus transfer board, while slots 20 and 21 are dedicated to IO-0002 extender modules.
This design supports hot-redundancy, seamless system interconnection, and structured cabling for ease of maintenance and enhanced operational safety in critical environments.
