Honeywell 900RR0-0300 Rack Assembly

Honeywell 900RR0-0300 Rack Assembly

The Honeywell 900RR0-0300 is a rack assembly designed for ControlEdge HC900 redundant controller architectures. It accommodates dual Control Processor Modules (CPMs) and supports redundant power connections, providing a hardware platform for controller redundancy and automatic failover.

System Architecture

The rack is dedicated to hosting two CPMs in a redundant configuration. In the event of a controller failure, the standby processor can assume control without interrupting system operation.

Unlike standard I/O racks, the 900RR0-0300 is intended for redundant controller installation. Distributed I/O is connected through separate HC900 I/O racks over the control network.

Technical Specifications

Installation

The rack can be mounted on a panel or DIN rail within the control cabinet. Redundant CPMs and power modules are installed directly into the chassis to create a fault-tolerant controller platform.

Frequently Asked Questions

Q: What is the primary purpose of the 900RR0-0300 rack?
A: It is a dedicated redundant controller rack designed to house two HC900 Control Processor Modules for CPU redundancy.

Q: Does the rack contain local I/O slots?
A: No. The 900RR0-0300 is a controller rack; HC900 I/O modules are installed in separate I/O racks.

Q: Does the rack support redundant power supplies?
A: Yes. The rack supports dual power supply inputs for power redundancy.
