900RR0-0001 Honeywell HC900 Redundant CPU Rack

The Honeywell 900RR0-0001 is a redundant CPU rack assembly designed for the Honeywell HC900 Hybrid Control System. It provides the mounting structure and electrical connections for redundant controller CPUs, supporting a dual-CPU control configuration. Furthermore, the rack accommodates the HC900 controller architecture and provides the connections required for controller components within a redundant control arrangement.

Technical Specifications

Product Functions and Features

The 900RR0-0001 provides the physical platform for installing and connecting redundant CPU components in an HC900 controller configuration. It supports the rack-level arrangement of controller hardware and provides the necessary electrical interconnections.

Key features include:

• Redundant CPU Support: Accommodates a redundant CPU arrangement within the HC900 controller architecture.
• Controller Mounting: Provides the rack assembly for installing and securing controller components.
• Electrical Interconnections: Provides connections between the rack and its associated controller components.
• HC900 Architecture: Designed for the redundant controller configuration of the Honeywell HC900 system.

System Configuration

The 900RR0-0001 serves as the rack assembly within a redundant HC900 controller configuration. It is distinct from an I/O scanner module, which performs I/O scanning functions. Therefore, maintenance personnel should identify this component by its rack function rather than classify it as an individual I/O module.

Furthermore, the rack should be identified by its complete model number when checking replacement requirements and controller configuration.

Frequently Asked Questions

Q: What is the Honeywell 900RR0-0001?

A: The 900RR0-0001 is a redundant CPU rack assembly for the Honeywell HC900 Hybrid Control System. It provides the mounting and electrical connection platform for redundant controller CPUs.

Q: Is the 900RR0-0001 an I/O scanner module?

A: No. It is a redundant CPU rack, not an I/O scanner. These components have different functions within the HC900 controller architecture.

Q: What should be checked when replacing the 900RR0-0001?

A: Check the complete model number, rack configuration and existing HC900 controller arrangement. In addition, verify the electrical connections and physical configuration before ordering a replacement.
