Description
Core Product Summary (Brand / Model / Key Attributes)
The Honeywell FS-CPCHAS-0002 (also identified as CPCHAS-0002) is a control processor chassis designed for the Honeywell Safety Manager system. It houses the Control Processor modules and provides the mechanical structure, backplane interconnection, and supporting power distribution required for system operation.
The chassis supports a redundant configuration with two Control Processors (Control Processor 1 and Control Processor 2). It incorporates watchdog timers and dedicated 5 V power supplies for each processor. Chassis identification is set by jumpers on the associated IO backplane. General-purpose inputs are available for external clock synchronization. The unit is typically installed at the top position in the cabinet, with one Controller chassis per Safety Manager system.

Detailed Product Overview
The Honeywell FS-CPCHAS-0002 serves as the dedicated chassis for the Control Processor section of a Safety Manager system. Each Safety Manager installation uses one Controller chassis, which is normally positioned at the top of the equipment cabinet, with IO chassis mounted below.
The chassis consists of a purpose-designed controller housing and the associated controller backplane (CPB-0002). These elements together provide the mechanical mounting, electrical interconnection, and power distribution needed by the Control Processor modules. In a redundant configuration the chassis accommodates two independent Control Processors, each equipped with its own watchdog timer and 5 V supply. Chassis numbering is established by jumpers located on the IO backplane, allowing the system to identify the physical position of the chassis within a multi-chassis installation.
General-purpose inputs on the chassis generate interrupts on a rising edge and are typically used for external clock synchronization. The mechanical design follows a standard 19-inch, 4 HE form factor, ensuring compatibility with conventional industrial control cabinets. Agency approvals include CE, UL, CSA, TUV and FM, supporting use in a wide range of process-safety applications.
Because the chassis is an integral part of the Safety Manager architecture, it is specified whenever a new or replacement Control Processor section is required for a Safety Manager system.
Engineering Selection Highlights
- Supports dual Control Processors → enables fully redundant Safety Manager configurations.
- Integrated watchdog timers and dedicated 5 V supplies → provides independent supervision and power for each processor.
- Standard 19-inch, 4 HE form factor → fits conventional industrial cabinets without custom mounting.
- Chassis identification via IO-backplane jumpers → allows clear addressing in multi-chassis systems.
- General-purpose inputs for external clock synchronization → supports precise timing applications.
- Agency approvals (CE, UL, CSA, TUV, FM) → facilitates use in regulated process-safety environments.
- One chassis per Safety Manager system → simplifies system architecture and cabinet layout.
