Description

Honeywell 900RR0-0101 is a redundant CPU rack for the HC900 process controller platform. It supports two redundant C75 controllers with separate power supplies and has no local I/O. The redundancy switch module occupies the position between the processors. Field signals are handled through separate I/O racks. The chassis organizes the controller hardware for the lead and reserve arrangement. This HC900 redundant controller rack provides the mechanical platform for a coordinated process control assembly.

04

Function

CPU rack
Dedicated controller assembly

The rack brings the redundant processors and their separate power supplies together in a dedicated controller assembly.

Lead CPU+Reserve CPU
Coordinated redundancy

The redundancy switch module sits between the processors, providing the system position used for status indication and mode control.

05

Product Applications

01Redundant process control

Use the dedicated chassis when assembling the HC900 dual-CPU controller architecture.

02Separated controller and field I/O

The controller rack works with remote I/O assemblies rather than accepting field I/O modules locally.
