FS-CPCHAS-0001 | Honeywell | Chassis for Control Processor

The Honeywell FS-CPCHAS-0001, also cataloged as the FS-CPCHAS-0001 Chassis for Control Processor, operates as a dedicated hardware component for mechanical housing and backplane power distribution within Honeywell Safety Manager platforms.

Hardware Specifications

Galvanic Isolation and 4-20 mA HART Loop Protocol Integration

The rack chassis incorporates isolated backplane power distribution tracks engineered to deliver dual-redundant 5 VDC logic supply feeds to plugged control processor units. High-density dielectric insulation between backplane traces provides physical channel-to-channel isolation across internal data buses. This shielding structure suppresses common-mode noise propagation and prevents power switching transients from corrupting analog input channels carrying 4-20 mA HART loop protocol signals.

Frequently Asked Questions

Q: What primary internal power rails are routed through the FS-CPCHAS-0001 backplane?

A: The backplane provides dual independent 5 VDC power rails (designated 5V-1 and 5V-2), drawing a baseline current of 0.05 A per line to feed control processor modules.

Q: Is hot-swapping or card replacement supported within the control processor chassis?

A: Module replacement capabilities depend on the specific redundancy configuration; in redundant controller setups, an offline module may be extracted without interrupting system execution, provided ESD precautions are observed.

Q: What mounting form factor is supported by the physical dimensions?

A: The chassis width of 48.26 cm corresponds to a standard 19-inch industrial rack enclosure with an overall height profile of 17.70 cm (4 U rack height).

Field Installation Guidelines

• Secure the chassis assembly into a standard 19-inch cabinet frame using four front-panel mounting bolts to establish chassis ground continuity.
• Verify that both 5V-1 and 5V-2 primary power supply feeds are properly connected to the backplane terminal blocks prior to inserting processor modules.
• Ensure a minimum clearance of 1 U above and below the chassis assembly to maintain adequate convection airflow for processor heat dissipation.
• Bond the enclosure chassis ground lug directly to the main cabinet protective earth (PE) bus using a low-impedance copper grounding strap.
