The Honeywell FC-IOCHAS-0001S is a single I/O chassis designed for process safety, emergency shutdown (ESD), and critical control applications in industrial environments. Constructed to accommodate Safety Manager I/O modules and associated bus components, the assembly features a 19-inch rack-mountable form factor with integrated backplane interconnects, key coding positions, and power distribution interfaces for process automation architectures.
Features
Designed for single Safety Manager controller configurations requiring dedicated I/O expansion.
Equipped with backplane connectors featuring SOURIAU 5159 mechanical key coding pin positions to prevent module misplacement.
Provides integrated bus printed circuit board (PCB) routing for internal 5 Vdc logic power distribution and watchdog signals.
Incorporates card connector slots for standard input, output, and special-function modules.
Features robust mechanical mounting design compatible with standard 19-inch cabinet frames and swing frame structures.
Applications
Safety Instrumented Systems (SIS)
Emergency Shutdown Systems (ESD)
Fire and Gas Detection Systems (F&G)

Installation Guidelines
Cabinet Mount: Install the chassis securely inside a standard cabinet or 180-degree swing frame using appropriate captive nuts and mounting hardware.
Module Keying: Ensure that all backplane chassis pin positions are properly populated with SOURIAU 5159 coding pins matching the intended I/O module type prior to card insertion.
Power & Logic Connections: Verify proper termination of the 5 Vdc supply line, 24 Vdc power bus, and watchdog signal lines via dedicated distribution boards.
Grounding: Connect the chassis frame directly to the cabinet safety earth bar using approved earthing straps.
Ventilation: Maintain unobstructed vertical airflow across all installed card slots to ensure operation within specified thermal limits.

FAQ
Which system architecture does the chassis support?
The chassis supports single controller configurations within the Honeywell Safety Manager system for standard I/O card expansion.
What keying hardware prevents improper module insertion in the slots?
The backplane connectors utilize SOURIAU type 5159 coding pins inserted into dedicated chassis holes matching specific I/O module keying.
What operating temperature range is permissible for the chassis?
The chassis operates reliably within an ambient temperature range of -5 degC to 70 degC when installed with proper airflow.
